Messier 27 - Dumbell nebula

This image was again taken in a cooperation with my friend Marcell Csőke (like the NGC6946-6939 from last summer). Our goal was to capture not jusst the core of the planetary nebula, but the so called butterfly wings. This is usually done by CCD sensors and narrow band filters, but we tried to do that with modified DSLR - CMOS sensors and with a simple UHC filter.

Scopes: 200/800 SkyWatcher Newton
Mounts: SkyWatcher NEQ6 pro upgraded
Guiding: Lacerta MGen autoguider
Camera: Canon EOS 600D and Canon EOS 550D
Exposure: 170*7 min on ISO 800 Baader UHC-S 2" + 18*7min natur (for star color)
Date: from 2016.07.29 to 2016.08.07 (7 nights)
