Getting the moon to fit into the shot!

I have a 350D
and the ETX-125 (opposite)
Using prime focus the moon is always a little too large to fit into the shot.
I have a 2 piece T adapter and both settings still leave it too big.
Am I looking for a focal reducer here or what?
Any help appreciated.

Yes, a focal reducer is the job for that.
Alternatively, you can take the a couple of images and let Photoshop blend them together. Image would probably be better as you are in effect using a higher magnification and increasing the level of detail on the image. This is what I used do with the LX90 and the images were far better than just one single image of an entire disc.

Thanks Mike.
I've been doing that alright but it's a bit of a pain.
Plus it'd be nice to be able to get objects in the one frame such as conjunctions and the like.
Cheers.

If you could somehow place the camera nearer to the back of the scope, it has the same effect as reducing the focal ratio of the scope (SCTs and MAKs), so giving you a wider field of view.
If your T-adapter is abit long it might be worth trying to find a low profile version. I have 2 here and they both give me different field of views.

Either that or get a focal reducer.

Yip. The T adapter comes in two parts and you can serew off one to make the camera nearer. I might have a quick look on ebay or the like for a modded one.
As for the focal reducer, I'm assuming so that optics are involved?If so is there a particular brand that winns out?
also, how do you work out what f ratio reducer you would need?
Sound, thanks lads.

Frank,
The most popular focal reducers are made by Meade and Celestron. These are desinged to screw onto the back of a SCT. To attach them to an ETX, you will need an adapter like this: www.astronomics.com/main/product.asp/cat...EQ07/product_id/MBCA
I did a check with the program "New Astronomy CCD Calc"; this indicates that with the ETX125 at present, the dslr can capture most, but not all, of the Moon. With a focal reducer, capturing an entire lunar disc should be no problem at all, assuming it will still come to focus: see this diagram here: www.astrosurf.com/benschop/Barlows_and_FocalReducers.htm .
However, when getting a focal reducer, don't get the f3.3 - this is intended for small ccd chips - won't work too well with the 300d. The f/6.3 would be the best bet.
Hope this helps,
