Hi Helen,
David’s advice is pretty much spot on.
I would de-bayer and use the green layer in Astrometrica as pseudo-V, i.e. set Astrometrica to use V band or the Gaia G band. You can then do astrometry and photometry. Have a look at the comphot page if you want to have a go at photometry. Depending on your pixel scale you can do the de-bayering by linear interpolation or simply by binning the two green pixels in each set of four. The latter is probably more photometrically correct. I have done photometry and astrometry using an ASI294MC camera and get good results.
Let me know if you need more detail on this. I hope that you decide to submit images and data to the section.
Nick.
