M33 - Triangulum Galaxy was taken on three perfect nights in Austria/Carinthia - Emberger Alm. This is one of the darkest spots in Austria with nearly no light polution.
I captured this image on my CEM60 fully remote with my TS Apo 115/F7 FPL53 and processed it only with Pixinsight.

I hope you enjoy it ;)
