Just did the auto combine and proccess of the Lights, Darks and Bias, a little bit of Digital Proccessing, they were taken mainly to see how the G-11 was tracking using the ST-4, I was happy with the result so I posted them.

did you use digital development on the image to bring out more stars?

Nice shots John. Thanks for jogging my memory, we had a bit of a binocular view of both those clusters last night as well out at Astroron's. I particularly like 2516 stuck out there all on its own. 3532 is spectacular but 2516 just seems to hang there in space.

Thanks for jogging my memory

Thanks Paul, I like 2516, those 3 orange stars really stand out. Galactic clusters make for good photos as well.
