Re: What causes stars to look like that ?

Hi Mike,
Thanks a lot for taking a look at my data.
The internet says 12 bit per colour channel for the Sony SLT58. It is from 2013…and maybe time to replace it...
I recognized the same effect with the binning. The camera has a pixel size of 4,3 µm combined with the 400 mm focal length I already got undersampled images and will lose resolution with binning. It is a tradeoff.
Good suggestions to test, I already did some of them. Like other ISO values. The camera has problems with lower ISO-values, you already noticed these bars left and right to the stars, they are from Sony rawdata filtering (I asked it on CN).
< To account for that I did use both DAF in Wipe and IFD in AutoDev.
->I will try that !
Shorter subs lead to a lot of data, but if that can help.
Best Regards
Sven
