Very poor conditions so decided to go for M3.
Download time for each image is about 5 secs. ( 11 for the 16HR )
This camera is definitely more sensitive than the 16HR. In fact it showed a
light leak that I did not realise I had
.( not on the camera). I have
corrected this but the image above was taken with the light affected frames.
GSO 8" RC working at f5.6 using AP Focal Reducer.
8 X 1 min exposures.
No dark frames or flat frames only bias used.
Managed to use the 460EX for the first time last night.
