Filter recommendations for CV Time Series

I am purchasing a new filter wheel with 50mm unmounted BVI filters for my QHY600M camera (used on a 14” SCT and a 6” FS152 Tak)

Should I consider a filter, other than unfiltered, for capturing CV Time Series data?

Is a Luminance, Blocking (UV/IR), or other filter preferred for CV imaging?

Thanks, Stephen

Filter recommendations for CV Time Series

I do a great deal of time-series work. I use a Luminance filter rather than totally unfiltered. I find the UV/IR block gives me better (tighter) photometric results. Also it's a shame to 'waste' a slot in a filter wheel as I also like to do regular LRGB imaging as well as the photometry. (I use my RVB photometric filters and get good images).

Cheers

Ian.
