Mike,
Too right, the first light feeling is unlike anything else...
The Omega Centauri image was the first taken for the night, and dew hadn't settled at that point. The swan I was hitting the secondary ever 2 minutes with the hair drier. M16 and M8 were pretty much both dried out before the run, then left for an hour or so to image...
I'm sorting out guiding as soon as possible... As I am quite sure that 6x10 minute exposures will be FAR better than 60x1minute.. I've organised an OAG (just the way I prefer to do things) and a SBIG ST4 guider... That should see me running nice long subs..
I'll re-pro the M16/M8 shots today, taking note of everything I do and doing my best to not cause any squares around the stars... I just can't think of what would be causing it in my processing routine.. But its worth giving it a go I say... Its noticeable in the processed tiff file, so I dont think its jpg artefacts.. but again, will experiment..
