Well I've been meaning to do this for a long time so last night I fixed up my camera piggy backed on my Meade LX100. Camera is Pentax istDL, lens cheapo Tamron zoom set at about 90mm . B setting 277 sec at f8 with ASA set to 1600.
The only processing I have done is with Windows photo editor - I tweaked about with the brightness, contrast andv hue. Oroginal size is 1.8 meg JPEG.
forgot to add that it is Eta Carina of course
