Assuming the weather clears here in Pennsyvlania before Spring, I am looking forward to getting my new (used) 18 inch dob out to view some nice deep space objects such as galaxies, nebulas, and globs. Could I ask the experienced observers to list their favorite Winter deep space objects so I can get a good starting list to work with?

Hi Mark,
Great images with that 12"!

Can you share the imaging train configuration?  I have not done much with a Newtonian for AP, but you have me interested.  I have an ASI 1600 and ASI filter wheel and an older Apogee U8300 camera with an FLI CFW7.

Do you use a guidescope with this and do you think you can avoid differential flexure with one?

I see you have the Moonlight focuser.  Does the corrector attach to that?  Then the CFW, and the camera?  Do you still feel that the best distance from corrector to chip is 56 mm and did you have any trouble fitting your gear on the back and still getting to focus?

Any help would be appreciated and thanks in advance.

Frank
