Here are my last two Ha panels from Ilford. Same rig, QHY9 - SMC Pentax-M 100mm lens stopped two down.
Only 9x10min for Orion and I reckon half of that was in the twilight so a little on the noisy side. Sagittarius is also 9x10min but it's way higher and a lot brighter.
I've got a bigger Orion here [1.75MB] and a bigger Sagittarius field here [1.9MB].
Lovely shots mark. I'll have to the the lens adapter for my camera and give it this wide field stuff a shot.
Thanks Sandy. There are heaps of various models on eBay. Most lenses have to be stopped down 1 or 2 stops. If they're heavy a set of tube rings in front will take off the weight. Focus by the number then stick a bit of electrical tape on the side of the lens so focus doesn't move. There's really no focus shift with short FL lenses. Very negligible. For dew, crack a 'hotties' heat pack, wrap it in a sock and cover the lens. No power required and that will last you all night.
No color for these but I have close ups I was shooting in color with the 8" at the same time.
