M100 The Blowdryer Galaxy (COM) - Blowing away the last nights of darkness, but not the clouds (C8 EHD)
Messier 100 (also known as
NGC 4321) is a
grand designintermediate spiral galaxy in the southern part of the mildly
northernComa Berenices. It is one of the brightest and largest galaxies in the
Virgo Cluster and is approximately 55 million
light-years from
our galaxy, its diameter being 107,000 light years, and being about 60% as large.
This is probably the last DSO-data I manage to get, before summer passes over and the astronomical darkness returns to a sufficient duration at night. It has dropped to below 1 hour over here, and pretty soon it will be non-existent, most nights obscured by clouds anyway these last months.
Two short nights of data (I also had a third night, but that was during full moon, with the moon in striking distance of M100, so a complete waste - how desperate do you need to be to even try that)
Way too short on integration time, just enough to get some detail and colour, and avoid graininess. Framing a bit off-centre, as I also wanted to have some neighbouring galaxies in the frame, as always RA aligned to X, Dec to Y
M100 & friends
C8 EHD, LRGB, 2600MM, EQ6R-Pro (no reducer, no BIN, no crop)
Framing: RA aligned to X, Dec to Y
Photons: LRGB 34x 10x 10x 10x 180s = 3:12 hours
