FREE Photometric Filters

I have a PARTIAL set of Omega Optics J/C 1.25" (threaded cell) filters I’m willing to donate to someone trying to broaden their photometry capabilities. Omega is now Chroma.

The U, R and I are in excellent condition.

I do have a V and B from Omega as well, but they have some degradation. In the past, on different filters, I have successfully used CLR (Calcium, Lime and Rust remover) solution to clean degraded photometric filters. But your-milage-may-vary.

I can ship between 1 and all to good home(s).

DM me if you can use them. Please, nobody just looking for “spares” or to resell.

Filters are gone to a good home. If you snooze, you lose.
