Attached are transformation coefficients for the BSM_NH2b system which includes an E180 scope and ASI183 CMOS camera. The SR filter has been transformed to a Cousins R filter.

Transform Applier…
Ken,
Transform Applier doesn't recognize the SR filter designation, should I be changing the FITS header to R on my images from NH2?
