Hello,
I saw some nice analysis of S50 dynamic range, with (I guess) the standard gain 80. Here e.g
https://www.astrobin.com/6260j0/0/
It would be nice to extend the range a little towards brighter stars.
This is certainly also possible if you (slightly) defocus, but has anyone ever done such an examination with gain=0 ? The gain can be set individually using the seestar_alp software, for example.
I could do that too, of course, but I don’t know how (I have Pixinsight, if that helps).
Thanks and CS
Thomas
