I haven't really had the opportunity over the past few months to get
much observing done, however a couple of weeks ago we had a very cold
snap here in London and the seeing was the best it could probably get in
inner London.

I tried my hand at astrophotography for the first time and I've attached
a couple of my more acceptable shots. I've darkened the pictures a
little with Photoshop to bring out the stars more, because of the light
pollution here.

I used an EOS 300 with a 300mm zoom lens on a manfroto tripod.

Also when attaching my SLR to the back of the 125 does the 125
effectively act as a 1900mm zoom lens?

Finally since I do not want the expenditure of ccd as yet, I am thinking
of buying a digital camera which I understand is just suspended on a
mount over the eyepiece. Does this negate the need for long exposure
since you are taking a picture of the image seen in the lens or are the
pictures taken as you would with a normal camera, if the latter is
correct presumably I need a camera with manual shutter/exposure facility
or would a full auto camera be ok. Any suggentions on a camera up to say
250 Sterling?

Happy New Year!!

If you attach the camera prime focus to the SLR, yes you are converting
it to a 1900mm TELEPHOTO lens of f/15 focal stop.

For deep sky photography at prime focus, you are pretty much limited
with a digital camera although they are great for planetary and
lunar....the exposures are limited to around 16 sec. to 60 sec. on most.
For the money the Olympus C-3000 is by far my favorite.

You must operate the camera fully manual, including focus and all
exposure settings for best results.

If you are really interested in short exposure deep sky work, you
probably should be looking more toward a CCD camera which you can pick
up very reasonably on the used market.

Good luck and thanks for the photographs!

Mike here: One comment: most digital camera do not have a removable lens and so can not be used at prime focus. Such cameras work well for afocal photography using an eyepiece (see the Astrophotography page and the Astrophotography Galleries for tips and examples).

Really enjoy your website.  Like seeing the results other folks get with
my telescope (and it makes me want to get a bigger one!)  This is one of
my first attempts with an ETX-60AT.   Used 2x barlow lens element
screwed into end of Meade basic camera adapter,  Canon Elan IIE camera,
ISO 100 film at 1/60 second.  Scanned the picture on Canon flatbed
scanner at 300 dpi, then adjusted quality in photoshop.

I just thought I'd send you a recent photo of a massive lunar halo which
I captured from my back yard in London UK. Taken with Canon Eos 300 with
a 28mm lens. Did not keep exposure settings.

Here is an image of the close call (1/4 degree) that Jupiter had with a
nice gibbous moon last Friday.  Too bad it does not show the 4 moons
that stretched out to the right of Jupiter.  It was quite a sight!

I was using a Canon F1 @ 1/60 exp. and 400 Konica Centuria print film at
prime focus on a Meade ETX.

My husband bought me an ETX 90-EC for Christmas and I've used it several
times with great views.  I'm also a photographer and have attached my
cameras (Canon EOS Elan and D30) to the telescope via the appropriate
T-ring.  I've taken many pictures however they are all slightly blurry.
This seems to be due to incomplete "tightening" or slipping of the
telescope when the camera is attached.  Any suggestions??

Mike here: Focus SLR cameras can be a challenge. If your camera has interchangeable viewscreens, switching to a clear one can help. If the blurring is due to vibrations from the mirror/shutter movement then all you can do is the "hat trick" technique. Cover the telescope aperture with a dark object but don't touch the telescope with it. All you want to do is block light from entering the telescope. Open the camera shutter and keep it open (using the Bulb setting). Let any vibrations dampen out. Flip the cover away from the telescope aperture for the duration of the exposure. Recover the aperture and release the shutter. With practice you can get short exposures and of course, this technique works great for longer exposures.

Subject:	T adapter for ETX 90

My old 35mm pentax has chosen to pass to a better life. I just bought a
Cannon EOS and I would like to buy the appropriate T adapter, but I am
hesitant to order it via the web not knowing what to ask for (i.e. part
number). There are no meade dealers here in Colombia

The Mead website only says here are diferent one for diferent cameras
but will not provide an e-mail for qweries (they stil rely on the good
ol' US Postal Service and prvide a mailing address.

How can I know what to order, pls help.

Fernando Pertuz
Mike here: There are two components that you need (see the Accessory Reviews - Astrophotography). One is the camera-specific T-Ring. The other is the Meade adapter. You can contact the online dealer and tell them what type of camera you have (it needs to have a removable lens). They will supply the T-Ring for that camera.
