I just bought a EQ mount with a RA motor for my DSLR and after figuring out how to use it (a dob only guy up till now..) i took these pics. not too great but im psyched! I attached a small refractor to it today so I am hoping to do better tonight! The focus is so hard to nail down, any suggestions?

Nice start indeed!

The focus is so hard to nail down, any suggestions?

There are many many threads on that subject, try a quick search. Basically there are software and hardware sollutions. So you either use something like a Bahtinov mask to create a diffraction pattern, or use software to analyse a star you pick in the image with a FWHM value. Not sure about the US EOS names... do you have live view?

you could give Download Digital Photo Software - Edit, Rename, Transfer, Load Images and Create Web Page Galleries a try, scroll down to DSLR remote pro (third one down). you will need a laptop connected to camera using the usb lead to download files from camera to laptop. Ensure you set the camera settings to pc connection not print/ptp or the software wont let you take a pic. Then just keep adjusting the focus take another pic until you get the correct focus you want.

The only downside to this is it is a 15 day trial .
