Here's a pic I took in Center Parcs trying out the flexi-focus(It's
Really good)I just stick the Canon Powershot A5 digital camera down the
eyepiece( 3x Barlow and a 9mm MA = 117x)This is with the ETX 70AT.

Please could you also tell me what F/6.3 or f/10 or all that means
Mike here: As to f/ ratios, that should be explained in your camera manual. If not, a good book on photography will explain it in more detail that I will in this email message. Basically, it is the ratio of the focal length of the lens to its aperture. The smaller the number the more light that reaches the film/CCD plane. It also affects the "depth of field" (see the camera manual).

Stephen Laurent here - Dripping Springs, Texas (it's 30m west of
Austin). Thank you so much for your site.

It has really helped me learn a lot about my ETX/125 and about
photographing the skys with it.

Many may not believe it but this shot of the moon was taken with my
Canon Elf Digital s100 camera - Hand held through my stock 26mm
eyepiece. I was amazed at the results and have many GREAT shots from the
past few nights. I did do some "darkroom" work on it in Corel Photo
Paint. The only work done in this one was contrast, glare reduction, and
corrective filtering.

Nothing has been added or taken away - no "tricks" - all could have been
achieved through the use of filters at the time of the shoot. I am a
digital artist and I am working on a series of altered images - Color
filters, negative reversal and multiple layering of images - Would be
glad to share some of those too if you are interested.

For now just wanted to send you this shot as thanks for all the help
your sight has given me and for the joy my scope now brings me armed
with your information.

I am very happy with the results as this was my first attempt and I got
the shot I was looking for to use in my project.

Thanks again

I noticed that the Canon astrophotos page hasn't seen anything in a
while, so I thought I'd toss these your way. Both images were taken with
a Powershot S200 @ 15seconds each( it can't do longer exposures). I just
sat it on a mini-tripod and let it go. No processing was done except for
darkening the background a bit to make the prominent stars stand out.

The object in the bottom left of the "teapot" asterism picture is an
American Flag that happened to be in the shot.

I was impressed that if you view the picture at the 1:1 scale, the
camera resolved the double star in the handle of the big dipper.

I know they aren't anything special, but its the best I can do so
far....its VERY cloudy ALL the time here in Erie, PA.

Keep up the great site!

Subject:	Recent image of M42 for posting on your web site
Sent:	Monday, December 2, 2002 18:02:13
From: (Richard Simon)
I have my ETX-125EC for almost a month, and have had good luck with
astrophotography.  The attached image of M42 was taken with the
	- ETX-125EC (with UHTC)
	- Scopetronix Maxview 40mm eyepiece
	- Canon G2 coupled afocally (ISO 400, f/2.2, FL=12.5mm)
	- The camera was set to "Daylight" color balance, low contrast, 
	  low sharpness, normal color.
	- 10 separate 15 second exposures
	- Images added using astrostack, adding the R, G, amd B channels 
	  separately, then combining the 3 sums to produce the final image.
	- The telescope was carefully polar aligned, and only the RA drive 
	  was in use.
	- Some adjustment of brightness and contrast was done to the final 
	  combined image.

My critique:  focus, focus, focus!  I think this setup could resolve the
Trapezium if the focus were perfect, and fainter stas would appear.
Making a 3-way "Hartman" mask for focusing is on my to-do list.  As far
as tracking: my scope was "supercharged" by Clay Sherrod, and the extra
weight of the camera was helping the scope to move in the right
direction (the RA motor didn't have to lift the camera).  I was running
on a fresh 12V battery.  There were three other exposures which had
smeared which I did not include with the 10 good exposures.  The Canon
does its own noise correction, so I didn't do any of my own.  It was 26
degrees F outside, which may have helped reduce the noise of the CCD.

Thanks to everyone on this web site for the many useful hints!

I discovered your astrophotography site recently and was very happy to
find people sharing their insight. Thank you Mike and thanks to all
contributors :-)

Currently, I have no telescope but I did some night sky shots last week
with my Canon G2 and the new 2x tele converter from Soligor.

I attach two photos which you may publish if desired:

The first is the original image taken with the G2 and 2x converter at
f=2.8/15sec. I reduced it in size to 25 percent, because the stars
turned to stripes due to earth rotation.

The main step was image processing afterwords. Basically, I reduced
noise from the original image and thus darkened it. Then I added the
same image 5 times to make low magnitude stars visible. The last step
was a slight sharpening and contrast enhancement. The second image shows
the result. Be shure tue tune your monitor contrast and brightness to
view stars down to magnitude 8.

Image processing was done on a Linux PC with Gimp.

Best wishes from the German Alps,

Equipment is a Meade DS-90ec telescope, 40mm Scoptronix MaxView
eyepiece, Scopetronix camera adapter, Canon G2 digital camera. This is
my first attempt at astrophotography.

I'm having a difficult time determining optimal focus. I'm trying to use
the little LCD screen on the back of the camera and at night it's really
difficult to see. It's not a problem with a bright object like the moon,
but the planets and stars are impossible to focus in this way. What do
other people do to ensure they are in focus? Not sure you'd have the
answer, but if someone out there does email me at


Mike here: Generally, when doing afocal photography you focus the eyepiece to your eye (if you wear glasses for distance vision you should focus using them) and set the camera lens to infinity. If that doesn't work for you then try the focus aid discussed in the article "Focus Aid, Autostar Aligning Aid" on the Telescope Tech Tips page.

I love your site!  It's was a HUUGE help to my wife who purcheased a
ETX125-EC for me for X-mas.  This is my first scope and I'm trying to
learn all I can about how to properly use it.  I just need to get a
tripod now and I'll be set!

At any rate I'd like to include a few moon pics I've taken.. My first
Astro shots ever.  I used the ETX 125 with the standard 26mm Eyepiece
and took these pictures through the eyepiece with my Canon A5 Zoom (sub
1 megapixel camera).  I sharpened once and tweaked down the brightness
using Paint Shop Pro as the original pics were a way to bright and a bit
washed out.  Anyhow I thought they were cool and wanted to share them.

The imaging was a bit tricky as I had to refocus the scope for the
camera using the Cameras LCD.  For some reason the images were blurred
when taking pics while the scope was focused ideally for my eyes.

I've got 3 images in JPG format that I'm sending..  Thanks again for
having such a wonderful site.

Moon Jupiter

Mike here: The Moon is slightly overexposed so reducing the exposure in the camera (however you do that with the Powershot) would help. Jupiter looks either out of focus, motion-blurred, underexposed, or all three. Keep the focus the same as with the Moon.

Great site, loads of info found it thru a Yahoo Group,

Now to my question,  I just purchased an ETX125 mainly for my daughter
who is developing a keen interest in astronomy, I am looking into the
possibility of using my existing camera for her to use for taking some
photographs with the scope,

I understand there are several methods available and was wondering which
would produce the best results considering the equipment we have.

As stated the scope is a standard ETX125, with a good selection of
eyepieces (Thanks to the current Meade offer)!

My camera is a  Canon 10D Digital SLR 6.5Mpixel.  As this camera has
good long exposure and high ISO Rating (Up to 3200), I am not sure if
the best results would be obtained through prime focus, or eyepiece
projection, (I am a little concerned about putting a heavy camera on the
eyepiece ring),

Any advice or pointers you could share would be gratefully received.


Mike here: See the Accessory Reviews - Astrophotography and Helpful Information - Astrophotography pages. And yes, you might have problems with a heavy camera; but a counterweight might help (see Helpful Information - Astrophotography). As to whether you should go for prime focus, afocal, or eyepiece projection will depend upon the object and what magnification you expect to get. Prime focus is like using the telescope as a telephoto lens (a 1900mm in the case of the ETX-125EC). Afocal lets you use an eyepiece to increase the magnification (same as eyepiece projection) but you shoot through the camera lens instead of removing it. In any case you will need the appropriate adapter for the type of photography and for your camera.

I had a question about taking photos with my digital camera, a Canon
Powershot S200. I was out the other night, and wanted to image M13 since
it happened to be there. I set the focus to infinite, ISO to 400, and
the exposure time to 15 seconds. I took 4 or 5 pictures with this
setting and they all came out totally black/blank, except for some
noise. M13 is a relatively bright object and I thought it would show up.
I know it was in the field of view, I checked that several times and it
was pretty well focused.

Any ideas what I did wrong?

Thanks, and thanks for your invaluable site!

Marcus Windrich
Mike here: I am not that familiar with the Powershot but you are correct, you should have been able to image it. Is the f/ratio adjustable? If so, was it fully wide open? When imaging DSOs with digital cameras it helps to keep the object as bright as possible, meaning that you should use a low power eyepiece. Have you tried shooting the Moon (good target right now)? Practice on it, then move to Jupiter (well positioned right now). Once you know your setup and technique works with the brighter objects, you can move to the more challenging ones.

Great site!  Thanks for all your hard work!

I am interested in getting into astrophotography with my ETX-90EC UHTC
but have yet to purchase a digital camera.  One I am seriously looking
at is the Canon A70 that is a 3MP camera that can handle exposures up to
15 seconds in length.  I have looked through your site but can't find
any references to someone using that camera.  Are you aware of anything
positive/negative with it or know of anyone who has used it?

Many thanks!
Alan Raphael
Mike here: Longer exposures might be nice, depending upon how you plan to use it. But in general, almost any digital camera can take nice astrophotographs of many objects, especially the brighter ones. If the camera can accept a remote release cable (or has a self-timer) you will avoid inducing vibrations from pressing the shutter button. If the camera has a built-in noise reduction mode, that can come in handy. If you can manual adjust the exposure settings, that is good. Also, you would like to be able to use one of the adapters to attach the camera to the eyepiece so you want to be certain you can get an adapter that works (which is usually the case if the camera lens accepts standard sized filters).

From: (Philip Campbell)
I have an ETX-90 and want to adapt my digital camera to it so I can do
prime focus astrophotography.  I have a Canon A-70 and the Canon LA-D52C
conversion adapter ring.  Here is a link to both the camera and adapter
rings web site:

Camera -

Adapter ring -
=848 5A001AA&CategoryNo=1734

The adapter ring gives me the option to remove the ring around the lens
of the camera and connect it so one could use other options that Canon
sells. The inside threads at the end of the adapter ring is 52mm and it
sticks out far enough so one can run the lens in and out.  I know that I
will need the T-Adapter #64 from Meade.  What else do you think I would
need to do both prime focus astrophotography and also use an eyepiece at
prime focus?

Thank you so much for your help.  Philip Campbell
Mike here: If the camera lens is not removable you will not be able to do prime focus photography (so the T-Adapter will be of no use). For afocal photography (shooting through an eyepiece) see the Accessory Reviews - Astrophotography page. The Scopetronix Digi-T System sounds like what you would want, assuming Scopetronix has an adapter for your camera.

Mike here: Yes, astrophotography can be additive. As to those eyepieces and the extension tube, I can't say but you can easily test but holding the eyepiece over each eyepiece and seeing where the focal plane is and see if that distance is too great or too short for your SLR.

It has been several years since I last e-mailed you but I always enjoy
your site.  I got a digital camera (Canon A80) this month and I tried to
take several photos of Saturn using the ETX 90 with afocal photography
just holding the camera to the lens.  Because I was afraid of camera
shake, I never slowed the shutter past 1/30 second.  The pictures were
100% totally black, although I had a very nice shot of Saturn in the
eyepiece.  Do you think this can entirely be due to too fast a shutter
speed?    Next weekend I plan on trying again with a tripod for the
camera with the shutter much slower.     Paul
Mike here: Could be a couple of reasons. Depending upon the "speed" of the ISO setting, 1/30sec could have been too short. Also, if the camera was not pointed directly into the eyepiece the object might not have been visible to the camera. If it wasn't visible on the display then the camera didn't see it. There are attachments you can buy or make that will give you better results. See the Helpful Information - Astrophotography page as well as the Accessory Reviews - Astrophotography page.

taken in video mode on the Canon for 10 seconds (and 143 frames)  Then
AVI file was decompressed and edited using VideoDub (a freeware program
designed to allow editing of video from the Canon A70).  Registax was
then used to select the best frames and the final pic was stacked using
21 of the 143 frames.  Your site has been a great learning place.  It's
only too bad I have to work too to support this exciting hobby of

I wrote a week ago that I was having trouble getting a good shot of
Saturn with my ETX90 and my digital camera (Canon A80).  Thanks for your
suggestions.  Before trying Saturn again I tried taking photos of the
moon-- I thought it my be easier and give me some practice with the
camera.  Enclosed is one of the shots using the camera on a tripod near
the eyepiece, cropped and darkened a bit but otherwise unaltered. 
Thanks for your help.   Paul

Just received my $99 Meade Special had to run outside (25
degree's out) and try them out.  Here is my first pic of the moon taken
with my Canon A70 digital camera.  This shot is as not
reprocessed or stacked (one of my best so far I believe)   I'm really
pleased with the quality of the optics.  Can't wait for a warmer night
to try them out on my ETX 125.

Subject: Focal Reducer For Canon Digital Rebel

From: Mr Bill ciabattoni (
I just recently purchased the new digital rebel and would like to try it
on some DOS.  I have an ETX-125 and wondering if anyone makes a focal
reducer that can be used with the t-adapter and an SLR on this scope.

Mike here: Since it takes the same lens as the 35mm Rebel camera I would suspect the same T-Ring Adapters would work.


I'm new at this so I maybe my first e-mail wasn't stated correctly. 
What I'm looking for is something similar to the scopetronix field
doubler that will reduce the focal length on my ETX-125 to f7, but can
be attached to my t-adapter and SLR.  It looks to me that the
scopetronix field doubler can only be used with a ccd imager or webcam,
not for prime focus SLR photography.  Do you know if anyone makes
something like this?

Mike here: The Shutan Wide Field Adapter will do this. See the Accessory Reviews - Showcase Products page. Since it normally uses an eyepiece, you will need an adapter that connects to 1.25" tube.

From: "Laluna, Robert (NIH/NIDA)" (
Just received my ETX 70 for Xmas..Is there any way to attach a digital
video camera to it?   I have a Canon Optura 20, digital video camera,
and was hoping to take some video of images "out there"

Thanks..Great site!!!

Mike here: See the Helpful Information - Astrophotography page for info on digital cameras. See the Accessory Reviews - Astrophotography for some adapters. HOWEVER, you can even shoot photos of brighter objects (Moon, Jupiter, and Saturn) by just holding the camera lens over the eyepiece. Focus the eyepiece to your eye and the camera lens to infinity. Try various camera settings and don't forget that DELETE button! Have fun!


Thanks Mike......Again, Great service from your site as well!!!

From: Paul (
Got out last night and tried for the very first time to both see and
photograph The Orion Nebula (M42). And it worked pretty well. It would
have worked even better had I been able to get the tracking working
properly but I think the weight of my equipment and the altitude and
angle of Orion at that time caused some slippage with my ETX 90RA (which
is understandable).

Anyways, this is a stack of 8 images that I did with Registax 2. shot
with my Canon G3 at F2 and 1 second shutter speed and at 400 ISO. I shot
through a Scopetronix 40mm eyepiece.


I shot Saturn again on 12/27 and the seeing was quite good following our
recent storms. The 5x Powermate did not work out too well (big, but
poorly resolved), but I was able to get some very nice shots using my
Meade 2x Barlow and Scopetronix 40mm eyepiece. I used the Canon G3 at 4x
optical zoom, F3, and shutter speeds from between  to 5/10 of a second.
I stacked and processed 15 of my best images in Registax 2. I am also
including a stack of 22 images that were taken with the 5x Powermate for
comparison so you can see how much bigger Saturn does appear when using



Here is a shot of Venus with the ETX 90RA. It is only about 13 arc secs
in size now so the real show with it wont commence till early May
when it will appear even larger than Jupiter but in a crescent phase. I
believe it is about 83% illuminated now. This is a stack of 36 images
done in Registax 2. the camera is the Canon G3 at 4x optical zoom, F3
and shutter speeds of between 1/100  1/200. I used the 2x Barlow and
Scopetronix MaxView 40.
