Description

A real challenge for a DSLR this  deep sky object. It is only 3 hours and 10 min under a bortle sky 4 but plagued with smoke and poor seeing. Certainly one of the worst summer for astrophotography The Optolong Ultimate had been very helpfull  to make out the Ha. But OIII is very weak in this SN so could be barely dectected on the picture.
