Score! i've started on M104 (have just under 5 hours at present), but it's out of sight behind a tree at my place by about 3am at the moment. i had been planning a quick run on a glob as well (M4) after 3am, but silly me slept through my alarm
Oh well, i'm glad someone had a full night of imaging
out of interest, what sub times would you recommend for a glob?
