RGBL filters on a CCD camera

Community

Got a quick question for the RGB folks:
For VPhot, which filter should be selected for a set of RGBL filters? No transformations yet. Just straight RGB filters in the filter wheel. Is that called TR,TG,TB? The FITS header says FILTER Green. Should MaxIM be set up so that the header says FILTER G or FILTER TG ?

Hi Ray,
for RGB astrophotography filters they should be called TR, TG and TB.

Thanks Josch
I know those get used for DSLR images with filters at the pixels.

Hi all,

Thanks to Ray for asking this question for me. Follow up question - as I’m looking to add filter mapping for my telescope in VPHOT, I noticed that TR, TG, and TB are not standard filter options. I don’t see them in the drop down list. Am I missing something?

Thank you!

Yes, Jen, they are nonstandard. I am changing V to TG etc manually in the reports, what to do…
