Ok gary .. what you say is likely what I'm experianceing , last night
two objects I know and can find easily enough didn't show up .
Yes I do limit my mag to suit my sky around 12
ngc 2264 and 2261 , the first dosn't show up as an OC
but would it as a nebula?... the second does its variability mean it
also would not fit my selection criterea ?
M1 is also not showing up on a messier tour under my same mag 12
selection ?.
thanks for the input
