Description

I loved to capture and process this target.
What especially still fascinates me is that there is a background galaxy (IC 4285) in the full frame, which is 1 Billion lightyears away - this easily means a new "distance record" for me, although I still didnt check the whole picture for background galaxies... but lets not move the spotlights away from M 51 ;)

Exposure times (@Bortle 5 over several nights):

L => 4.5h
R/G/B/Ha => about 1.75h each
