Howdy
Did all of 80 mins on this one (8x10 mins ISO 800) with UHCS and uv/ir filters trying to go as deep as I can. My unmodded 300D can barely record this nebula even with long exposures. The modified camera (350D ) makes all the difference with the hydrogen alpha light. It was justabout at the zenith when I finished imaging it. (amazing how far the scope has to move in 80 mins to track the object). Images taken just a few hours ago. Conditions good but rather humid, when I packed the scope away the overcoated primary mirror got some dew on it as the warmer air in the garage evaporated dew from the ends of the tube, oh well I will clean the mirror later.

Thanks. Its the 2nd or so longest exposure run ive ever done, was tired at the end of it lol, time seems to go faster if I have the TV on, was listening to the footy show as I took the images

Thanks all.
Dont worry about the weather, the good stuff has gone now, its raining and very cold lol. Hope it clears for our astro society viewing night Saturday night.
The mirrors all clean, thanks to the excellent QI Chin quartz overcoat. I gently washed the mirror with car wash, rinsed and used a chamios to gently dame dry and water drops left over.
