Description

This image, sum of 102 180 secs unguided subs, has been taken from my home terrace during the night of 04.08.15 - temperature was unbelivebly hot. Camera used was a modded Canon 600d, telescope a Vixen ED114 + Hotech field flattener, filter was an Astronomik UHC-E eos clip, but in front of the optical train, I have added a Baader IR-CUT. Mount was a Vixen GP D2. Stacked with DSS, and processed with PS (curves, levels, star elongation and noise reduction). This object is quite faint, but not that faint. It was not visible in the single frames, but it's clear enough in the stacked on.Thanks for looking.
