This evening i decided to look around with the scope and the famous livestacking feature in SharpCap. The idea was not to exceed 10 mins overall on each target with 8 seconds subs, no autoguiding, no processing (except an automatic histogram stretch provided by SharpCap). It was surprisingly fun! I looked at so many objects this night - i dont know, about two dozens i believe? I saved the nicest images, so here they are (without any post-processing):

A: Messier 57 (Ring Nebula), 66 x 8 s = 8 mins 48 secs
B: Messier 27 (Dumbell Nebula), 38 x 8 s = 5 mins 4 secs
C: NGC 7789 (Carolines Rose), 21 x 8 s = 2 min 48 secs
D: Messier 39, 26 x 8 s = 3 mins 28 secs
E: Messier 17 (Omega Nebula), 19 x 8 s = 2 min 32 secs
F: IC 4703 (Eagle Nebula), 35 x 8 s = 4 mins 40 secs

What do you think, which one is the nicest and should be the 'final' revision of this evening?

PS: Another reason for this EAA-evening was the fact, that my cooling system does not work properly at the moment. That's why i took the images at 5°C. See here for details.
