Hi, I'm having an issue calibrating my flats with dark. The problem is only occuring with my OIII data. Flats and Dark Flats for Ha and SII are fine but I'm getting the following message on the OIII:
** Warning: Neither master bias nor master dark found to calibrate Flat frames (filter = OIII, binning = 1, exposure = 11.75s, length = 50)
The exposure times and all other details are the same for the dark flats and flats (11.75s) and the other FITS header data all matches.
I've taken new flats and dark flats (slightly different times) and I'm still getting the same message.
The calibration files were taken using the flat wizard in NINA.
Any ideas?
Thanks
Greg
