Photometric filters seem to be disappeared from the market...can someone tell me where I can buy (or get a used) 2" V filter to start photometry with my new RASA 11 and ASI 6200 mono?
2inch UBVRI set from optolong, I have not found those seperately yet.
2inch V filter from Chroma
You might also search for 50mm round unmounted filters and fit it into a 50mm mounting cell with 2" thread. Edmund Optics produces those amongst others. https://www.edmundoptics.com/p/50mm-mounting-cell/11757/
