It depends per camera type, but most astronomical cameras and the WATEC are usually tending to be red sensitive and will give you 'fainter' magnitudes than true visual estimates.. For my WATEC, I mapped the actual measured magnitude (in the "red" band) of a large number of stars against their catalogue visual magnitude, to come up with a rough conversion equation to make the photometry compatible with visual magnitude estimates. - Marco ---- Dr Marco Langbroek e-mail: marco_at_langbroek.org web: www.langbroek.org Twitter: _at_Marco_Langbroek ---- _______________________________________________ Seesat-l mailing list https://lists.seesatmail.org/mailman/listinfo/seesat-lReceived on Sat May 06 2023 - 07:40:26 UTC
