Description

I'm always so amazed at the photon collection ability of my 8" ONTC Newtonian. This is 12 hrs of LRGB data from sea level in Bortle 8 with a waxing Moon. NGC 5474 also makes and appearance in the lower right. Its a dwarf galaxy that is gravitationally locked with M101, similar to the Magellanic Clouds and the Milky Way.  Now if only I could get my neighbor to turn off their flood light.....
