I am pretty new to planetary imaging and have a hard time understanding what my camera is recording, what it should be recording and why. My weapon of choice is the ASI290mc mounted on a NexStar 6" Evo and my target is Jupiter. I record on a 4-core laptop with USB3 and SSD, hitting 100fps worked even before the beta most of the time and I always set the ROI to just fit the object I'm recording. I know (I think) that I should always record without debayering, with as high a framerate and low gain as possible to get over 50% histogram, debayer later in AutoStakkert.
The camera can record in 12bit but all my footage is recorded with 8bits according to SER-player. 8bit gives me only 256 colors while 12bit would give me 4096. But FireCapture has only either 8 or 16 bits and although my cam can only record in 12bit, the SER-player says it's 16bit if I chose this setting in FireCapture. Now I know from forum posts here that the software always writes 16bit into the SER-header regardless of the cameras abilities but how do I know what my camera really recorded?
Also, when I switch to 16bit mode in FireCapture, the 3-colored histogram turns into a single-color wave but SER-player still says that its 16bit RGGB. This leaves me with the following questions:
- For Jupiter, Saturn and Moon, should I record in 8bit or 16bit and why?
- Do I lose color information when recording in 16bit as indicated by the mono-color histogram or can the information still be debayered afterwards in Autostakkert?
- If I don't lose color information, how can I balance the histogram in 16bit? In 8bit I need to dial down the green channel to have all 3 colors on roughly the same level. If I don't adjust it, my pictures have a green tint.
- Is SER the best format to record footage or should I opt for TIFF/FIT/BMP pictures, what works better with AutoStakkert?
Hope someone can clarify this because after spending half the sunday on google I still couldn't figure out which recording settings to use for my cam.
