Yes, you are right, it's ASI294 Pro, cooled to -15 °C. Image is usually flipped both horizontally and vertically because i like to see things as they appear really in the sky to our eyes...BlackWikkett wrote: ↑Fri Mar 08, 2019 1:39 pmSeeing the initial dark frame I recognized this as a ASI294 and taking a cursory look at the log file this is confirmed. Normally the amp glow starburst pattern is seen in the upper right hand hand side of the frame. In the example provided the main amp glow starburst is in the lower left side and a minor amp glow is in the lower right. This looks to me as the image is flipped in both horizontal and vertical orientation so the amp glow appears in the lower left side of frame.
No, absolutely i'm sure, no.
I take so carefully my darks, matching perfectly the temperature (i took different darks for 5 °C changing, so i'm very careful in taking darks), the exposure, gain. But brightness? Yes, there is a brightness slider, but just for pure visualization on the pc screen. I always know that this brightness slider deals only with screen brightness, just for seeing better the live view of the image. It isn't an inside camera parameter as gain, to deal and play with. So I left always brightness to 20 i think. Never considered as a real parameter...So what do you mean as "using the lowest brightness setting you can"?BlackWikkett wrote: ↑Fri Mar 08, 2019 1:39 pmMy experience with the 294 and using dark frames in live stacking you need to be very careful to apply the exact settings you will be using to capture your light frames. Exposure, gain, brightness need to be exact. Also recommend using the lowest brightness setting you can.
For flats, as almost everybody indicates, i use the lowest gain, in my case i use unity gain, that is 120. Set the flat box light to match the histogram around 45-48 % matching around 30.000 ADU (you can read the ADU in live histogram), for a 2s exp. I take 20 flats. I read many hours on forum about the correct flat exposure and i also tried many different exposure, from 0,5s to 4s: nothing changed.
I already had read this topic 2 weeks ago, when i was finding info about taking correct flats...
As i already told before, with SC 3.1 i didn't have these problems with dark and flat applying during live stacking, with the same equipment, same ways of taking darks and flats, same flip image, etc....
Thanks for trying to find a solution for my problem.
