I collected data over five nights from March 17th to 27th. The integration is a bit uneven across channels, but it's probably enough now. I stretched the background a bit and some dust started to show (or so it seems to me).
Galaxy M100 (other designations: NGC 4321, ZWG 99.30, UGC 7450) is a spiral galaxy located in the constellation Coma Berenices. It is situated approximately 55 million light-years (16.86 million parsecs) from Earth.
This spiral galaxy was discovered by the French astronomer Pierre Méchain on March 15, 1781, and was later included by Charles Messier in his catalog as number 100.
