I took several M57 images, but only kept seven of them. I took 10 darks, 20 flats and 20 bias images (first time taking bias images).
I use Batch Preprocessing to stack everything, but the outcome was a master light that was black and white. When I open the light master, it says "GRAY 1:4 Light_Binning_1".
The image was taken with a Canon 650D (4Ti) unmodded. I've taken images of M57 before and didn't have this issue. The only thing different is I have flats and bias frames with this stacking.
The light frames that I used to stack these, open up as RGB frames when I open them individually with PixInsight. So, they were color to start with. :/
If anyone could tell me where I went wrong, I would be very thankful!
Thanks,
David
