Some nice images of this recently, but here it is at about 1000m focal length, with NGC4976 off to the right, something hiding behind a star top centre and another 4 little smudges buried amongst the stars. This was the first galaxy I ever found, through a 4" Unitron at Lake Moogerah in SE QLD in about 1983.
Anyway - touching reminiscences aside, this was taken in suburban Perth through a 10"f4.5, QSI683, on a G11-G2. About 8 hours in total with 2 hours each LRGB, 5 minute subs for L, and 10 for the others. I'm still having some issues with stray light from nearby streetlights, as there is a bit more data in there, but the background starts to break up into some odd bands and curves if I stretch it much more.
Comments and recommendations welcome!
