Hi Marc,
Excellent image and a nice scale for the chip with the new 5 inch. Your hard work has surely paid off. Were you using a Meade DSI?
You might want to experiment a little with exposure times. I'm aiming at around 40 images per session to decrease the noise and working out from my imaging time how long to make the exposure. Works ok on bright objects. Dimmer ones will no doubt need longer. These chips are so sensitive its amazing how much detail comes out even at short exposures. Have seen galaxy shots posted on this website through a GSO 12 f5 with only 5sec shots - but lots of them made me think this may be a good way to go. If you are using a DSI with envisage the shorter subs will give you lots of images for drizzle to. Also less critical if some cloud drifts across etc.
Others (more knowledgable) may no doubt argue for sure stay at 10mins but I like experimenting around with things. My impressions are it does seem to work pretty well.
Cheers
David
