This is the Pinwheel from Borrego-Springs, California at Nightfall last weekend.

Pinwheel was captured with an St-7 on a Celestron 9.25 SCT @ F6.3, Losmandy G-11. Exposures were L (8x4:45) R&G (3x8:00, 2x2), B(3x10:00, 2x2). Processed in Images Plus, Sigma Combine, and Photoshop.

Nice Job Alex,

You captured some good detail in the dusty areas.

It would be nice to have a bit more FOV on this one wink

Hi Alex,

Nice job. I noticed that you are at F6.3 with the 9.25. Are you using the celestron focal reducer. I too have a C9.25 (although I image mostly with my NP101) and when I have tried to image with the focal reducer in place I get some chromatic abberations which I attributed to the focal reducer.
