Taken on 7-12-07 Conditions weren't good, light cloud forming then it would clear also a few wind gusts.
David decided to try imaging anyway (probably not ideal conditions but he was getting frustrated with the recent weather here)
He hadn't taken longer exposures than 5mins with the 6MP Pentax so he wasn't sure how much the camera would capture or how far he can push it.
This is a stack of 7 light frames 6x6mins 1x7min 40sec ISO800 ICNR
Stacked DSS Processed PSCS2
It was difficult for me to get a smooth background in processing (hope I haven't overdone it!) We're reasonably happy with our first attempt and will try under better conditions to capture better data.
