Hi all!
I've had a lot of issue this time with my telescope... It was completely my fault (yes I've made a principiant error ). I've dismounted the camera assembly to make a cleaning and collimations of the optics and, when I've re-mounted the camera on, I didn't noticed the screw adapter was off axis. I've then checked my collimation on the stars and boom! Everything was totally out with odd shaped stars everywhere! Meanwhile I was gone to an astrocamp on top of a remote mountain! The sky was excellent and my camera was badly locked into the focuser! I've tried to collimate my scope off-axis but it is really an RC used in prime focus with a Rhoss corrector and it was impossible to get good stars... After struggling with rudimental tools trying to unscrew the locked camera, I succeeded and I've fixed the camera but the optics where again very off. During all of that issues, I was running on battery and recharge with solar panels since we have no AC power on  the mountain! Anyway I've tried to image something useful and I had to crop about half of the imaged field, every time moving the subject from night to night to a different part of the field in the hope of a "mean" rejection of strange artifacts. 7 days where passed with very few acceptable datas... I've then spent 4 more nights in a different location (not good as Mount Pollino, the astrocamp location that still is one of the best places remained in Italy for dark sky) this time with AC power and tools to work on collimation but with much worse sky... Anyway these are the only datas I was able to get in about 11 nights! I've struggled with editing but the final image is worth the work in my opinion. It is a straight RGB+Ha image with no luminance. At the end I was able to collect about 8hrs of data for each RGB channel with 600" subs plus 4 more hours of H-Alpha with 1200" subs on my Takahashi Epsilon 210 f3 using a QSI 683 WSG8 CCD camera and Astrodon gen2 filters (5nm HII). I've added more datas at crescent resolution on the Cocoon area previuosly taken with much larger telescopes (up to a 500mm RC) in my last attempt at this subject You can find between my images here on Astrobin (You can see the acquisition datas about)...

If You've read until now than thank You for taking all this time!
