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.
