I may have a little too much on the saturation without protecting the stars. Or I'm doing something wrong in my treatment.

Greetings This is my last astrophoto during the night of August 26 to 27, 2019. Photographed from my terrace, in Vex (Switzerland). I think there is no need to introduce this nebula. I photographed it with my Televue 76 + x0.8 focal length reducer. CCD ZWO ASI 1600 with Astronomik filters. The Orion Starshoot kit on a 55mm viewfinder and the PHD 2 software. The mount is a Skywatcher NEQ6 Pro Synscan. 21 x 240 sec Ha 6nm 15 x 240 sec OIII 6nm RGB 15 x 120 sec for each color And Pixinsight for pre-treatment and treatment

Hello Thank you all for your welcome messages. @Demonperformer Indeed, Borg asks for a backfokus of 60mm. There is a ring, supplied with, of 5mm and my salesman machined me a spare part of telescope / Wheel with filter and CCD to the good dimension. The problem can come from the "Astronomik" filters 1mm thick. I have to test it next night. The question I ask myself: Since where do you measure the backfocus? Greetings to you

Hi everybody My name is Guillaume, 32 years old and I am Swiss. I speak French and must be content to go through "Google Translate" to communicate with you. I practice astronomy since very young (when I was 10 years old) and astrophoto since 2013. It will be said that I have actually been able to practice astrophoto since the end of 2016 because of my move which is the ideal place to practice this passion. I work mainly with Televue 76 and its focal length reducer x0.8 CCD Zwo ASI 1600 and its filter wheel with filter Astronomik Orion Starshoot set for autoguiding and PHD 2 And a Skywatcher NEQ6 Pro Synscan. For now, the main reason for my registration is that I just acquired a BORG 55 fl 3.6 and can not do the Back Focus. I spotted a person who owns the same set. I also think that other people can help me. Excellent day to you

Hi James Your image is cool, bravo. I just bought the Borg 55 fl 3.6 (Version 2019) and I also have the ZWO ASI 1600 and filter wheel ZWO. How did you mount your ZWO 1600 on the Borg? Because I can not get the Backfocus (60mm) Thank you and good day Guillaume
