Quote:This is a great shot. I think I have found a new target when my camera gets back. I probably know the answer to this question, but could I get a similar results with my f/4.9 and a 2x barlow? I know barlows are usually frowned upon unless it is for planetary or lunar, so I am guessing no.

Quote: If the seeing is not good to excellent, you basically can't do anything with that scope.
Quote: But if your sub exposures are long enough to get you up out of the readout noise of the camera, using a good-quality 2-inch Barlow in this instance to get you to f/10 should be ok

Quote: I have been on your interesting website several times and have learnt a lot. Thanks! Your beautiful NGC 891 image caught my attention a few days ago. I also work with long focal lengths (2.1 m and 2.3 m) at f/5 and would have thought 18MP on DX format with 2 m of focal length is a strong oversampling. Does it still make sense to use a modified (or unmodified) Canon 600D over a Canon 20Da at 2 m focal length? Do you win anything with it?
Quote:Jerry, WOW!!!! I just got a C11 on a Cgem mount. when the skies clear and I can use it for the first time, could I expect ANYTHING close to this with my Nikon D50? Any response would be much appreciated. Thank you for a wonderful picture.
Quote:That is an awesome image. Maybe someday I'll get one just like it
Quote:Gorgeous image! Amazing result for only 60mins and F-10. With a DSLR! That too unmodded!
Quote:Awesome picture as always, I noted the you changed from Tak mount to Losmandy. Wonderful change
Quote:That is a very cool image. Well done.
