ASI294 color images

Post by Rrosenberg8 » Mon Oct 28, 2019 12:44 am

How do I tell if the ASI 294MC Pro is creating color images? They by default in Nebulosity and AstroPixelProcessor are B&W and all of the options in Astropixel don't seem to give good color images. I use the ASIAir to acquire the images. Are there settings I'm missing??
The ASIAir works great especially with the recent updates. IT controls my iOptron CEM40 well, and good integration with SkySafari.
Thanks

All FITS images have a header with info about the image and it contains info about the Bayer pattern as well. This is the order of the R, G and B pixels in the sensor which is needed for Nebulosity and APP (and other software) to decode the B/W image into colour. It probably is RGGB (because this is used by most sensors) but it may be different.

In APP got to tab 0 (RAW/FITS) in the dropbox next to Pattern select RGGB (or the pattern that you can find in the FITS header) and tick Force Bayer CFA. When you then process your images again they should come out in colour.
