Again I set Linear HDR mode, tried to shoot in normal mode, stars start to burn out, but in this one the read noise is 46000, read noise 1 and most importantly dynamic range 15.5 stops and 16 bit output. Well, and stars with the monochrome camera became truly colorful.
Oleg, hello! I've been racking my brain over a problem and wanted to consult with you, just to get your opinion.
I was imaging with the Askar sqa 106, using narrowband filters: Hydrogen, Oxygen, Sulfur. Camera: ZWO 183 MM. Target: the Tulip Nebula in Cygnus.
The Hydrogen came out fine, but when I started shooting Oxygen, the object disappeared((
Same thing with Sulfur.
I increased the gain and exposure time, and it got a little better, but only very slightly.
What's the issue? Is it a lack of aperture or light-gathering power? Or is the sky still too bright? But that doesn't seem likely.
The sky is still bright in terms of oxygen, and there isn't much sulfur either, so it's also bright there. For you, night hasn't fallen yet—it's still twilight.
Thanks, Oleg, you always come through. I pretty much thought the same thing.
Then another question if I may.
I'm planning to shoot the same object in LRGB today, will that work?
As for the camera, I don't have another monochrome besides the 183. I know it's not the best.
