ASTAP and Bias

[MalcolmP]

I cant see anywhere in ASTAP for my Bias subs !
( I am looking in the help file but y'all may be able to help me get there quicker !! )

I have previously been using DSS with only Bias, no Darks, because I have read on the forum that with the Canon DSLR sensor temperature fluctuating so much that only Bias is best.

Morning mate,

I would use bias as  darks (instead of darks) on ASTAP, 

but 

@han59 is the ASTAP dev (or one of them), - maybe he will advise you better once he has time

Thanks, yes I'll give that a try, it can whirr away while I am doing the domestic chores and later compare with/without and with DSS !
I had googled and found a longish thread in another forum, inwardly digesting

Ooops, I am ashamed to say that I am AN IDIOT ! ,
I had done a browser search in the help document for bias and found nothing, lots for other offset,,,, but gulp,, I have just searched it again and  found several bias refs,   !!!!
I must be going blind, or cant speel bias the first go?,, must be too many late nights ! Sorry.

You put bias in dark flats in ASTAP, they’re the same thing either use DF or bias you never use both , either one will be subtracted from your flats ,

So good, I'll carry on with just bias. Thanks
