Problem with ASI224MC snapshots

[Cosmic Geoff]

Last year I took some snapshots of planetary nebulae with my ASI120MC camera and Sharpcap v3.1. These were .png files and I had no problem debayering them in PIPP to output colour TIFF files.

This year I tried the same with my ASI224MC camera and the results remained obstinately mono even when I repeated the snapshots on a second night.

In the end I connected up both cameras in my kitchen with the fisheye lenses and got the following: (I have omitted the settings which seemed to make no difference). All with Raw8

ASI224MC:

.ser selected (defailts to .png for still: Mono 😥

.png selected: Mono

FITS selected: colour with GBRG debayering

TIFF: unsupported compression error 5

ASI120MC:

.ser selected (defailts to .png for still: Colour with GRBG debayering 🙂

.png selected: Colour with GRBG debayering 🙂

FITS selected: Mono

TIFF: unsupported compression error 5

To me these results make no sense at all.  I presume there is some way of converting a FITS to a .jpg or TIFF if I need to do that for distribution?

(Also note that the debayering setting apparently differs between the cameras.)

Update - since posting the above I have determined that item 1 above debayers to mono with GRBG (the setting previously used for ASI120MC), mono with GBRG, false colour with BGGR and true colour with RGGB, so I hope that's the problem solved.

It still does not make sense to me.
