Hyperstar Rosette in Ha

Did an all-nighter last night. Pretty cool after Thursday when my QHY5 stopped working so I had no guiding. Tonight I had the lodestar. That worked flawlessly. Problem is that I don't have a way to fit on my finder scope so I had to piggy back my APO on top of the C11. Total rig weight 25kg. The G11 didn't seem to care much. I did though when lifting everything up there. Still feeling it this morning.

Very wet but clear from 11:00pm onwards. This is 10x300s on the Rosette. Finally got the primary tilt spot on. Residual top left corner is a final tweak with the tilt of the focal plane on the hyperstar in the front of the scope then I'm there. On axis details are nice and sharp. Little black strip on all stars at 5 o'clock is a piece of flocking that decided to give way inside the tube and was hanging. There's always something.

Big one here - 2669x1997 [2.53MB]
HD here 1920x1437 [1.27MB]

*Added some uncompressed 1:1 crops of the central area with some details.

Thanks for looking.
