Description

Cocoon Nebula is usually not presented in SHO palette because the oxygen iii signal is really weak (see image below).. I wanted SHO target but my initial target was unfortunately hidden behind building so I went to alternative target - IC5146 - Cocoon Nebula. It was interesting (and disappointing) experiment
Second night I gathered LRGB data but I couldn't see a lot of nebulousness (bad seeing and not enough data), so I decided to just put LRGB stars to existing SHO.

It's nice presentation but the white nebulosity around the core is missing. I will come back to this target soon and do it in more traditional LRGB way and with much more data

In the middle of the night I started to gather Oiii data and when I saw it's lacking of any useful data I was a little bit disappointed, but decided to continue with it (Sii, Ha and Oiii from left to right):
