SH2-115 in Cygnus in SII Ha OIII and RGB. I collimated it 2 years ago after stripping it to wash the optics....Its such a stable scope even with the extreme heat of Spain.
A lovely data set
Thanks for looking

Gorgeous image! I struggle to tame the reds when using HSO palette, and I love the blue and orange contrast you've gotten here. Great detail too, tack sharp for sure.
Thank you..I only used 3hrs of the s2 from the one data set....There is a few more hours on its way for this set....Exposures were 3hrs in S2, 4 in Ha and 5, in O3....approximately....so the ratios are way out in reality but the object is so bright there's enough signal to play with....
It would have also helped with this one if the subs were 180s and not 300s it would have given a better rejection during stacking increasing sig/noise and there would have been only 3mins of seeing in each frame compared to 5mins, potentially making it sharper...So I can see improvements.
