It's been a while since I last used it, but on Jan 11th I took several
webcam images with my ETX 90 and combined them into a mosaic view. I
hope it helps to encourage ETX users to see what such a little telescope
can achieve. Time and again it amazes me how fantastic the optical
quality of this thing is. The webcam was a Philips ToUcam, each part of
the mosaic is about 150 stacked frames.

First of all lots of succes and clear skies for 2003!

I need some good advise, maybe you can help me?

I am getting my etx 125 ready for planet photography. I already used a
toUcam xs (soon a pro), a 5 meter network cable, a barlow 2X and soon i
will have a electric focuser.

Now my question; it is hard to find a planet back when you lost him out
of sight with that small field of view of a webcam. Now I wanted to find
something to have a kind of guidescope with another webcam to have a
larger field of view on my screen. I fabricated with an old camera
objective (4/200) and another webcam a sort of guidescope, but I have no
idea how to fix it on my ETX!?

I even want to use software that correct the scope movement using that
guidescope (i have the connection cable kit too). It is possible that i
have to use two toUcams pro for this because of the lightsensivity. Do
you now if there exists some software that can track with the guidescope
AND use in meantime the other webcam to stack or film the pictures of
the ETX tube? I already thougt about IRIS but this one is not able to
recognise two different webcams.


Kris Van Mol
Mike here: You could likely make a "piggyback" style adapter for the 2nd webcam. There are some tips on the Help Information --> Astrophotography page. As to autoguiding the ETX, that would be a challenge as the ETX drives don't track that evenly and the Autostar does not have any "PEC" (Periodic Error Correction) capability. But I like your idea of the 2nd webcam for centering the object. I don't know of any software that handles two webcams simultaneously.

Yes Sir, I am! Do you remember when you saw your first fuzzy picture on the Notebook LCD? You'll probably never forget it! Looking through your site in the 'Helpful Information - Astrophotography' and 'Guest Astrophotography Gallery - The Planets' area, I found some interesting photos to compare. Some are better, some are worse. Well, there's a lot left for me to learn, try and 'play around' with stacking. But what I would like to discuss with you - or some readers of your lovely page - is: How does someone like e.g. Xavier Ray-Robert create a 'high-glossy' image out of fuzzy brute pictures (at least - or even more - 'fuzzy' than mine)? In my experience, all treatment of pictures - whilst or after stacking - comes to an end either at sharp, clear pictures containing artefacts instead of details or at still somehow fuzzy pictures showing only 'real' details'. Again, what's the 'trick' with it (yes, I tried different filter combinations and grades)? Always clear skies - it's raining here in southern Germany..... Dieter
Mike here: Stacking does improve image "quality" by "removing" noise. This noise can come from atmospheric distortion or imager electronic noise. However, it can also create false details if carried too far.

I thought that you may be interested to know that I have revamped our

includes a section recommending 'Home Astronomical Observatory kits' for
schools, which are centred around the ETX70, ETX90 or a Newtonian/Dob.
There is also a page about imaging.   We are starting to have great
success with our Philips Toucam Pro webcams and I attach a picture I
captured of Jupiter and two of its moons using an ETX 105.   The picture
is composed of one exposure to capture the moons and 15 for Jupiter
which were then stacked with astrostack and adjusted using photoshop.  
All exposures were taken within about 5 minutes of each other.

Your readers who are beginner Sun observers may also be interested in our 'Our Star*' project, designed to help our astronomers make studies that link their observations with small scopes to data from the best ground and space-based observatories. Also on the site are details about our forthcoming link with NASA through the International Space School Educational Trust. I shall be visiting Kennedy Space Station in May and hope to "network" (personally I prefer the description "talk and make friends"). If there are any NASA people in the ETX community I would very much like to hear from them. A lot has happened in a year but I've said it before and I'll say it again; I don't think any of it would have happened without the information from the ETX community on your site and your personal help and advice.

Mike here: One is obviously the Moon but the other (smaller image) is not that obvious that it is Mars. Looks too large a disk for the ETX-70AT and the phase is wrong. I suspect the webcam moved during the exposure. Mounting a camera to the eyepiece works out much better for longer exposures. The Moon is slightly overexposed so if you can control the exposure, shorten it.

First of all, congratulations on such a fine ETX site.  Without a friend
of mine pointing out your site and the wonderful tips it contains, I
don't think any pics would have materialized from the ETX.  One of the
first modifications that really helped out the scope was the drive mod
with the 2 switches.  Before that, it was a lot of locking and unlocking
the RA to stay on a planet (or whatever else) only to watch the object
drift out of sight once the RA was locked.  Now I just push the correct

Thought I'd enclose my first Toucam Jupiter pic taken on April 27th.
Approx. 300 frames staked in K3CCD tools.  Unsharp mask also applied.
Taken through diagonal of ETX-90RA.  Enjoy!

K3CCD tools is a freeware stacking program.  I never even heard of it
until I started reading the QCUIAG message board on Yahoo.  Although I
used just the plain Toucam software for capturing the Jupiter avi (my
Pentium 166 is just too old to accept K3CCD), K3CCD allows capturing to
avi, aligning, stacking and some post processing, like histogram and
unsharp masking. So, once captured to an avi, I sent the avi to the P4
for processing with K3CCD.  The program is pretty much automatic- it has
a planetary guide that takes you through the processing step-by-step. 
You can even hand select the best frames for stacking, although I didn't
do it for the pic I sent you.  I also have Registax which is extremely
useful for the sun and moon, but it didn't help as much with Jupiter as
K3 did.  The hardest part of the entire process seems to be both proper
webcam settings for capture and keeping the object being imaged centered
on the tiny ccd (with webcam lens removed). The URL for K3 is  I couldn't even begin to see the red spot
until after stacking in K3CCD tools, so it does seem to make a
tremendous difference.  I also have a regular digicam (Nikon 4500), but
I'm sold on the idea of using webcams for planets due to the great
results obtained.  The greatest advantage is being able to take an avi
and separate it into its original frames, and there can be up to 600
frames to work with.

have like to give the actual settings, but I forgot them.  Anyway the

used Registax to align and Photo Explorer for further enhacement, ie...
focus, saturation and balance.

I'm considering going to a long exposure camera but I'm not sure how difficult it is to take good deepsky photos. As with this image it took some time to get to this point. I want to make sure it remains fun and not a labor. If you have any opinon on this it would be greatly appreciated. Thanks for your time, Chuck Falcone

Subject:	ETX-125, ToUCam, and MARS!!!
Sent:	Thursday, July 24, 2003 07:01:46
From: (Michael Lang)
I've been having Autostar problems since loading 26eD (reference my
question a couple weeks ago on training and target distances). After
reviewing everything I could find on your fine site pertaining to my
problems, it occurred to me: (1) Mars is getting close fast, (2) I've
been dorking around with my Autostar and ETX-125 in Alt-Az alot more
than I've been viewing Mars, (3) I get about 1 night in 7 of relatively
clear skies, and (4) I've got a new ToUCam Pro (740K) Web Cam I've never
used on my ETX-125.

So I got up at 2 AM last night, polar aligned my ETX-125 using the
no-brains (and no frustration) non-Autostar hand-controller, slewed
around to Mars, and it was nice and steady with details showing. I
installed the ToUCam+2X Barlow and Laptop, and HOLLY MACKEREL  I was
getting pictures like those I see on the web!

My advice to all out there with an ETX, drop the Autostar, if your
having problems, buy a ToUcam and the 1.25 inch adapter, a prime focus
1.25 inch screw-on adapter, and a 1.5 to 2X Barlow (get a good one like
a Celestron Ultima) and get going on your Mars observing tonight using
the Hand Controller. I tracked Mars until dawn with very few corrections
required in over two & a half hours. The controller is responsive,
doesn't rubber-band or do any of the AutoStar silliness, is simple to
use in the dark, and keeps my blood pressure low. This all gave me the
time I needed to focus on just imaging Mars, tweaking the ToUCam
settings, experimenting with the K3CCD software, and just practicing.

A few additional pointers:

(1) Since the CCD in the ToU Cam is so small, it's pretty tough to get
the image of Mars on the chip,especially at high power. So, align the
Finder Scope using your highest power eyepiece (I used a 4.8mm Nagler).
Then defocusing Mars so it forms a large blob that extends into the "4
quadrants" formed by the finder scope crosshairs. Adjust the Finder
Scope so the blob equally fills each quadrant in the finder. Keep
tweaking everything until Mars is centered in the eyepiece, and Finder.
Then install the ToU Cam, (and remember to flip the ETX mirror down to
the prime focus position), and if the image is centered, great!! But it
won't be. So don't get frustrated, just start searching. Have the Laptop
positioned such that you can see it out of one eye, while looking into
the finder with the other. Get comfortable in your observing chair, and
slew the scope around using the lowest speed on the Hand Controller, and
all the patience you can muster up. Eventually you'll find Mars. When
you do, either make a mental note of how the blob looks over the
crosshairs, or try and tweak the finder (but that's tough to do without
loosing Mars again). I found getting Mars back into the field of view
was easy by just positioning the defocused-blob over the cross hairs the
same way as when Mars is displayed on the laptop screen.

(2) Drag an extension cord out to power your laptop (scope to if you
aren't using a big external battery), my Laptop battery died and I lost
15 minutes.

(3) Build a LOOOOOOOOONG lightweight foam dew shield, or you're front
lens will probably dew-up, and you'll be sad. I followed the advice of
the gentleman over seas, and the results are just wonderful,

(4) Buy some of those shock-absorber pads for your tripod feet. They
really work and are worth every penny,

(5) Get comfortable, put your Laptop on a small table, like a lawn
furniture table, or one of those fold-up dinner tables, and put your
self on a chair or stool (note: this may seem silly, but a 3-leg stool
is much better than a 4-leg when your moving around a 3-leg tripod -
less bumping), and finally, get your scope outside hours before your
gonna get serious about observing, and let it reach thermal equilibrium.
The images are dramatically improved after the scope cools down.,

(6) Either install an electric focuser, or a "flexi-shaft" focuser, and
then keep tweaking/experimenting with the focus during your session,

(7) Use K3CCD (shareware) to record your AVI's, it's much better than
the Phillips S/W that came with the camera, And set the camera "gain"
low, and the "shutter speed" high - but experiment until you understand
the relationship between these adjustments. Also play around with the
"Daylight", and "Outdoor" settings until the color displayed matches
reality (as viewed in the eyepiece)

(8) And finally, practice using everything during the day, or inside.
It's easier to get familiar with everything in the light when your wide
awake, than to fumble at night for the first time.

Now as far as what to do with the saved images, I haven't done anything
yet. But from reading many Web "how-to-do CCD astrophotography", it
seems "Registax" is the preferred post-processing, "first step". And if
you have Photoshop (I do), that seems to be a good choice as well. 
Also, checkout the Sky&Telescope article from July (or August ) of 2003.
There's a good article on how to get started in CCD astrophotography.

I'll post my Mars "first light" pictures in a few days when I figure out
how to process it. Unless observig conditions keep me outside the next
few nights.

And one last thought: this is really FUN !!!!!!!

The camera/eyepiece adapter I use on my ETX-125, simply screws onto the
threaded ring on the back of the ETX (after removing that threaded cap). It
is about 50 cm long, and is also threaded on the other end, such that you
could screw that threaded cap onto it.

The inside diameter is 1.25 inches, and there is a small knurled screw at
the "eyepiece end" to lock your eyepiece or Barlow + camera adapter into
the threaded adapter. I can't remember where I ordered it - but you might
try searching Mike's site or asking Mike. I would be surprised if
Scopetronix doesn't stock a similar adapter.

I was outside all night Friday (July 25) and captured over 20 avi's using
the setup I described in my previous message on Mike's site.

I noticed that seeing gradually improved over several hours, no doubt due
to the scope temperature equalizing, and Mars climbing higher in the
southern sky (and I have to tell you - I'm VERY JEALOUS of your location -
your view of Mars is going to be fantastic !) I also noticed a blue fringe
on one limb of Mars, apparently due to atmospheric refraction as a result
of Mars being so low in the sky.

I used K3CCD to capture the avi files. My Laptop is slow, so I captured 5
frames per second to avoid dropped frames, shutter was 1/33, gain & gamma
were set low. I used a 2X Celestron Ultima Barlow, Thousand Oaks Light
Pollution filter (visually, this seemed to improve image contrast)

Telescope was polar aligned, and I used the Hand Controller versus

Side Notes: I ordered a Baader Contrast Enhancement Filter, and will let
you know how that works after I receive it.

Also: I intend to try a Wratten 23A light-red filter next. I tested it on
the ToUCam, and the camera is plenty sensitive with a 23A filter, and red
filters are supposed to bring out surface detail, and limit sky glow,
atmospheric turbulence, and perhaps "blue-fringe".

K3CCD has a small symbol in the toolbar that says "FFT".  I'm not exactly
sure how it works, but it appears to generate a star-pattern with rings
when the best focus is achieved.

And finally - I noticed that setting the ToUCam to image in Black & White
increases resolution in my tests images of a red brick wall several hundred
feet away, illuminated with a red Light Emitting Diode.

And now back to my Mars image:

In my 18th avi (3:55am), everything came together - the atmosphere was
stable, telescope focus was perfect (get an electric focuser if you don't
have one, and modify it per info on Mike's site, to focus as slow as
possible. Also I've made a special mechanical modification to my electric
focuser that completely eliminates mirror shift - for about one dollar ! -
details to be provided in another message )

So in the 18th avi,  I could tell the conditions were just right, so I set
K3CCD to record 200 frames (in previous attempts I only recorded 50

Here's the results after stacking 57 of the best of 200 frames using K3CCD:

Then I used Photoshop 3.0 to sharpen the image using "Gaussian Blur" + "Unsharp Masking" + Contrast & Brightness adjustments:
Finally, I used Photoshop to adjust the color to more accurately reflect the real color of Mars (at least what I think it looks like from various spacecraft images. I considered some pretty drastic measures to correct the blue fringe around the southern ice cap (air-brushing), and just couldn't do it. And actually, it reflects the reality of my viewing location:
Not believing the results, I referenced recent back issues of Sky & Telescope, and found a pretty close match in the June 2003 issue (page 97). It looks like my image may be of the "Syrtis Major" region. And there you have it. Let me just reiterate: if you have dew problems in Africa, get a long dew shield, and get comfortable: have a chair, and locate your laptop on a table. Your going to spend long periods sitting very still watching the monitor, adjusting focus, centering Mars, focusing, adjusting the camera settings, re-centering, focusing, holding you breath........... But when the sky begins to brighten, and you finally go inside and begin processing your catches from the night, the thrill of comparing your first picture to a map of Mars, and seeing a match is just too exciting for words!

Subject:	Mars, ETX125 and ToUCam
Sent:	Monday, August 11, 2003 21:51:57
From: (the Christensens)
I always enjoy your ETX web site.  I have had my ETX 125 for more than a
year now and I am comfortable with its operation thanks to the wealth of
information you provide.  I recently aquired a Phillips ToUCam Pro along
with a 1.25" eyepiece adapter.  I wanted to share my images and
experience with you and your readers.

After some study, I decided that the Phillips ToUCam Pro was the best
way to go.  It has a CCD imager instead of the CMOS type in less
expensive webcams and has better than 1 lux sensitivity.  The removable
lens makes it easy to attach the telescope adapter, you simply unscrew
the lens and replace it with the adapter.  The camera assembly weighs
less than most eyepieces so no counterweighting was necessary.  The
camera and telescope eyepiece adapter were $150 from Adirondack Astro
Video (

The first clear night I attempted to capture Mars, but my results were
poor.  I was using "auto mode" and the provided "Video Lounge" software
that came with the camera.  The videos were grossly overexposed - all I
got was a fuzzy white ball.  After more research, I downloaded several
programs, and finally settled on K3CCD.  It seemed to have more features
than I understand, but menus I could follow and operate.

This past weekend (Aug 9, 2003) skies were clearer and I once again
tried to get Mars.  I knew the images I previously captured were too
bright.  I unchecked "Auto Exposure".  Then I adjusted the gain,
brightness and contrast to their center values, then adjusted the
shutter speed to where I could clearly see the polar cap and some dark
features at 1/250sec .  I fiddled with the gain, brightness and contrast
some more (shifting them to the left) to improve the image quality.

I found it difficult to keep Mars centered and it was also difficult to
focus - there is a few seconds lag between the time the image is taken
and presented on the notebook's screen.  Slow cautious deliberate
focusing and aligning was required.  I rarely use "SPEED 2" on the
Autostar controller, but I did for this.  (I owe much thanks to Clay and
Dick for their Autostar programming information, without which the creep
after beep and lag in the motion controls would have made this

K3CCD has the ability to capture various video streams, being able to
select the number of images per second, and the total number of images,
etc.  I settled on 2 images per second for a total of 100 images, which
produces a file about 45mb.  I proceeded to capture several videos,
varying settings slightly.

I subsequently "aligned and stacked" the best of them to achieve the
included picture.  While not as good as many I have seen, I was pleased
with my "second attempt".  You can clearly see the southern polar region
and dark markings.

I want to further experiment with colored filters and use a 2x barlow. 
I will send future results and I hope to provide some instruction as
well.  I found this process very "trial and error", but I believe it can
be simplified so that others can have a successful and positive

But to my dismay and frustration I have not found any " Tips or

webcam(settings, etc.) or stacking using Registax.

I did a web search and found 2 guides written by Alan Chu, these guides
really helped me image and process my first 2 Mars photos(attached). 
The addresses for the guides are

and (Microsoft Word files).

As a beginner I couldn't have got thruogh Registax without them.

The 2 photos were taken with my ETX-125(Polar Mount), a Meade #140 2X
Barlow, a ToUcam Pro with settings from Alan's guide.  I then stacked
and processed in Registax, again using the settings from Alan's guide.

I can't wait to try for Jupiter and Saturn this winter.

Alan Chu enclosed an interesting Word document about WebCam (title:

I have one but I am not able to have the Barlow focal length to compute

Sent:	Monday, October 13, 2003 16:58:21
Have a reasonable, cost effective solution to astroimaging that may be
of interest to your visitors.  It includes the Mighty ETX-125, an Orion
Color eyepiece feeding the Snappy video digitizer.  If you would like, I
can put something together for your site.  My pics include sun, moon,
Mars, Vega, Aldebaran, and Altair.  Got one of the Pleides last
night..that would be a Plee-Ah-Dee I suppose.

Here's some info that pretty much sums it up.  Bottom line, the specs on
the Orion eyepiece say it only goes to 2.5 lux and can be used for
planetary and solar imaging only.  These two bright star images seem to
defy that information.

I'm relying on the Snappy Video Digitizer to bring the images into my laptop. Snappy hardware, if you can find one, was really hot about 4-5 years ago. Basically it does an 8:1 oversample of the images in the highest resolution mode. The bad news is that if you're not rock solid on the tracking or mounts, the image is blurred. Recommend at least Snappy 3.0, then download the 4.0 firmware (freeware driver) which adds a nifty snap viewer so you can readily compare pics. The software has preview windows for precise focusing and all sorts of controls to bring in exactly the type of raw data you need. Bad news is Snappy is unsupportable as they are no longer in business. This is a real downside but since I already had the unit, I figured what the heck. Despite what the documentation says about only being able to image bright planets, the moon and sun, I brought in Vega, Altair, Aldebaran and one of the Pleiedes (would that be a Plee-ah-Dee) recently. If you have a field tripod, don't forget to use the wedge and equatorial tracking as opposed to Alt/Az. Because the Orion eyepiece behaves like a 7mm eyepiece (270x) it requires a really stable mount. Cobbling this rig together is very enjoyable and satisfying. The images will only keep improving. Can't wait to use the ETX in the equatorial mode...sort of overlooked that little point up to now. Clear Skies. Max

After a few frustrating nights chasing deep sky objectes, I was
reasonable successfull recently . Octoberfest is over and the light
pollution over southern Munich has improved a little bit. Nevertheless
it is one of the limiting factors for urban deep sky backyard
astronomers. The contrast is image quality significantly.

There are some black traces visible in the pictures . The reason for
that are a few hot spots in the CCD. The darkframe substraction leaves
therefore dark traces, which give an information about the drift of the
picture during exposure.

The webcam brings a new quality in the use of the ETX, therefore I would
like to thank all the people, which provide such helpful tips and
software like K3CCD or Registax for hobby astronomers. They do really a
great job!

Again and again: Thank you for your great site!

It has been a long time since I last emailed you but let me start off by
offering you my congratulations on your web sites 7th anniversary! Well
done and many thanks for the countless hours you spend to keep this web
site up to date for all of us to see and use. Through the resource
information available on your site I was able to make the following
decisions and acquire the right components for my scope:

1)       Picking the ETX90EC was based on all the feedback available and
recognizing the limitations (optical and mechanical) of this scope. It
has turned out to be the right investment for me.

2)       Investing in an electronic focuser was based on feedback from
your website. I purchased one on e-Bay at a very reasonable price.

3)       Acquiring an Autostar 495 also at a reasonable price and using
the information and the safe load technique described on your website to
turn it into an Autostar 497.

4)       Wiring schematics so I could make my own cable to connect my
computer to the Autostar.

5)       Admiring all the images on your website and using these as a
jumping off point to research web cam imaging and acquiring a Logictech
QuickCam 4000 to do my own imaging.

6)       Identifying all the tools required to do the imaging such as
Registax for post processing, K2CCDTools capturing and processing images
and QCFocus as a focusing aid and image capture utility.

7)       And finally to acquiring ScopeDriver to automate the operation
and control of my scope which as you read on will become very relevant.

Without your website I wouldnt have come this far and certainly wouldnt
have achieved as much. It has opened up a new realm of astronomy for me
and has allowed to me to do the things I could only dream of as young
astronomer some 35 years ago.

Which leads me too today; the following is a composite of images that I
have taken using my ETX90EC and web cam. All images were taken at prime
focus and without the aid of a Barlow lens. Ive used both Registax and
K3CCDTool to post process the images and do final touch ups and
composition in Adobe Photoshop.

The image of Mars was taken on October 4th at about 1:25 AM local time.
The image of Saturn was taken on November 11th at 1:42 AM on what was
probably the clearest evening Ive seen since I started imaging. Jupiter
was captured at 7:46 AM local time on Nov 22nd. I was really thrilled
with the outcome as both Saturn and Jupiter are first time images. Im
still working on my technique but the instant gratification that web cam
or CCD imaging offers has inspired me to do more.

When I imaged Mars in October the weather was quite nice here in
Edmonton, but it was sure to change and it did. Anticipating the colder
weather I pursued the ScopeDriver option as a way to operate my scope
from the warmth of my home. I had some initial struggles with the
program but through the dedicated effort of Steve Hutson, ScopeDrivers
author, many e-mails and using the information I could provide him, he
was able to fix a long standing but isolated issue with the Autostar
communications component of ScopeDriver. I highly recommend this product
to those of you who are thinking of putting together your own Robo
scope, the support I received was fantastic! Many thanks Steve! You can
find out more about ScopeDriver at

So with all the tools in place my first opportunity to image with my
Robo ETX came in early November. Some initial trial and error work lead
me to the evening of November 10th and morning of November 11th where I
spent almost 4 hours imaging (with a 2 hour TV break in the middle) from
the comfort of my kitchen using ScopeDriver to operate the scope which
was sitting outside in the -5 degrees Celsius (23 Fahrenheit) weather.
The scope, webcam and software worked well in spite of the cold. The
operator was thrilled to stay warm (call me a fair weather astronomer)
and was able to show some of the images of Mars to my wife and kids who
were wondering what I was up too. They thought it was kind of neat too!

Not to be outdone I wanted to capture an image of Jupiter and my chance
arrived early on November 22nd. However the temperature had dropped
significantly and on that morning it was -24 degrees Celsius (-11
Fahrenheit). I wasnt sure if I should and even how the scope would work
in that cold weather but I pushed the scope out onto the deck, with a
crude polar alignment and quickly centered Jupiter and started imaging
once the scope started to cool off and settle out. With the sky starting
to get lighter I tinkered with the focus using ScopeDriver and QCFocus,
adjusted exposure parameters and started imaging. I was amazed that
scope worked quite well during the hour or so that it was outside. I was
able to track and adjust focus without a glitch, although once post
processed I realized the focusing could have been slightly better or
that the scope hadnt fully settled out. Ill continue to work on it and
hopefully under better weather conditions but have proved that Robo ETX
can and will work!

Thanks again for the wealth of information your website has provided. I
hope others will be as inspired as I am and experience all the fun that
amateur astronomy has to offer!

additional to your articles showing the size of Mars and Saturn with

'What to expect from Saturn with ETX-125 and ToUCam'

Now - during winter 2003 / 2004 - Saturn is situated very good for
observation. It reaches opposition on December 31st, 2003 and is
positioned high and bright in the sky. The ring system shows wide opened
in our direction (southern hemisphere) with abt. 45x20" in diameter.
With an ETX-125 (5", 1900mm) and a ToUCam the planet looks is as follows
without a Barlow lense, with 2x Barlow and with 3x Barlow:




Don't worry about false colors, less details, dark and 'fuzzy' view; it's a sample frame out of the avi-file. There may be better ones as well as worse. I decided to take the 2B-avi (there are VERY rare moments of best seeing where you can use the 3B; remember that equals magnification far over 600, but YES, sometimes it is possible) and resized by 2x / stacked / filtered / optimized / cropped by 0.5x the best 800 out of 1900 frames (with K3CCD tools & IrfanView) and this is the result (south up, east left):
It's a nice one, but not optimal. Still a little grainy, so you can continue to optimize (or wait for a night with better conditions) But all that computer work takes a lot of processing power and user time! You see a nice, large ring system with the Cassini division, natural colors, the shadow of the plant on the rings and of the rings on the planet, a dark belt on the planet and the dark northern hemisphere. And yes, if you WANT you may imagine to see even a 'faint glimmer' of Encke minimum. But be careful; you easily may produce 'details' by 'enhancing' - where there are none! So that's what you can expect from Saturn with ETX-125 and ToUCam. Dieter Wolf (Munich, Germany)
