Oh. Man you’re going to love that Hyperstar. Let me know if you have any questions about it I’ve been using Hyperstar almost every good night for a couple years and I live up in Enid.
Dennis C We’ve been evaluating the images from a couple nights out. I think maybe I’m overexposed. Is 60 seconds too long? I’m getting a lot of sky glow. Seems crazy to me after nights of 10 minute subs
Dave Compton what camera are you using? For broadband With my ASI1600mm in enid’s darker skies I’m doing 30s LUM and 90s RGB at 0 gain. I previously lived in Vegas and the sky glow led to extremely short subs w LRGB (~5-10 sec) being optimal so I didn’t even bother doing broadband unless moving to a dark site. Narrowband was fine though w subs near 90-180s at unity gain depending on which filter/moon/haze etc. For EAA I use an ASI1600MC and I’ll run the gain up to 300 and stack many short subs (5-10s) and get a pleasing enough (for EAA) image using Sharpcap in just a few minutes of those short subs. I don’t do this often though and i want to experiment a bit more to optimize it this spring. I didn’t see what camera you’re using so that’ll change it all a bit if you want to be optimal. What camera do you have for it?
It’s a ZWO 294mc pro. I like it but the dark frame has a bad light glow. It calibrates out though. I can get good calibration at pretty much any exposure time. It may be that my area around the campus is a little light polluted. I’m using the baader moon and sky glow with it now but might fork out for the l-enhance or another filter.
Dave Compton on my ASI1600 I usually aim for a mean ADU of approx 2x-3x the ADU of a bias frame at the same temp/gain. I then round up to the nearest reasonable number that I have in my dark library. Not sure how your camera would be any different. The individual frames aren’t impressive but they do stack up quickly and nicely with extremely low noise (more noisy at gain 300)
Wow 🙌 i love the set up, I'm looking forward to seeing some images taken with the Hyperstar.....nice upload 👍
Awesome set-up, would love to see some images from this rig!
Good Luck Dave with that rig! Hyperstar will change the game for you! Hope no more bad storms and clear skies!
Ray's Astrophotography Thanks!
