Hi All, 2 images taken today. (I can only post one of them for some reason??? Oh Well, just the one then :) )
QHY462C
Lunt60THA
PromA settings =
Gain=477
Exposure=0.5165ms

Close Up Settings=
Gain=99
Exposure=0.5165ms

Stacked in Autostacker4, Wavelets in Registax6 and final processing in Afinity Photo V1.
Got a lot to learn on the processing side and would welcome any tips.

Thanks

Carl

Hi Carl,

not quite sure what has happened with the second attachment - sort of looks like it is there but it isn't. You ought to be able to add multiple files and either place them in the post or if you don't they appear at the bottom as download links.

Good work on getting out and getting some more images. To me the top of the image looks overexposed, which might be in the original capture video or might be coming from the processing - I'd suggest replaying the original video in something like SERPlayer to see if the top of the image is overexposed and if so, adjust gain/exposure down further the next time. Once you have correct exposure throughout the image the rest of the processing will become easier

cheers,

Robin
