I ordered a qhy183 osc.
I plan to pair it with either my 600mm f4 newt, 480mm f5.6 refractor or soon to be 400mm f4.2 refractor and of course the 135mm f2 and 50mm lens for wide fields. The small pixels should play nicely with these optics and if calibration works the way I want it to, a second 183 will be paired with the osc, probably a mono.
how many darks are people using after lets say a 4hr lrgb session with 30-60s subs?
Nice choice Wes!
For me, with 60" subs. I'd probably take an hour of darks for mylibrary. You can reuse it for a long time which is nice. (Assuming same gain/temperature)
