M77 Galaxy

Picture
M77 and NGC 1055 in Cetus

was the first data acquired by my 10" OGS/RCOS Ritchey–Chrétien telescope at New Mexico Skies.
M77 at lower left (also designated NGC 1068 and Arp 37) was discovered by Pierre Méchain in 1780.
Oriented face-on to us, it is one of the largest galaxies in the Messier catalog, with a central core measuring 120,000 light-years across.
Estimated to be 48,000,000 light-years from us, this barred SAa-type spiral is a Seyfert galaxy with an extremely active core,
emitting both plasma rays and X-rays. Most interesting is its extended arm system, with prominent dark lanes clearly visible.
At upper right is NGC 1055, located 30 arcseconds away, which, in actuality is 
442,000 light-years. 
This near edge-on is an Sb spiral, and is gravitationally bound to M77 in a system, which includes several other smaller galaxies.
​This beautiful galaxy and its spectacular dust lane was discovered in 1783 by the great William Herschel.
