Description

This image is the result of a collaboration of passionate friends , Frédéric, Axel, Thierry and myself ( Philippe) around the remote control observatory settled in North of France (Oise) . Waiting our C14 hyperstar to be repaired,this target is by far the faintest we have ever worked on with the little REDCAT and  even with over 32 hours of subs for OU4, the object remained incredibly faint. The outcome presented here tries to leverage the faint signal of the object without overprocessing it
