Would you like to have some nebula filters that work well but don’t cost an arm & a leg? I sure did, and I finally found a good solution – acquire some inexpensive overstock (NOS) bare filters from a wholesale US manufacturer and mount them in conventional 1.25” and 48mm filter rings (from color/tint filters) for use by amateur astronomers. I use these & like ‘em a lot! (worry less about damaging them in the dark)

Up-side? Each filter comes with a spectral transmission plot so performance is KNOWN (see pix). Each filter functions very similar to its brand-name alternative for around HALF the cost!
Down-side? No familiar brand-name written on it (obviously the filter ring label doesn’t apply anymore – mark it however you want.)

One BIG advantage: you will be pleased with your filter or return it in original condition & I will refund 90% of its purchase price. Now that’s low-risk! I value my feedback rating.

Types & Prices (a few of each is available):

Oxygen-III (O-III):
* over 85% transmission, 10nm primary bandpass....1.25” size = $49 (SOLD)
.......(similar to Thous. Oaks LP-3 @ $89-$179)..........48mm size = $69 (SOLD)

Hydrogen-beta (H-Beta):
* over 85% transmission, 10nm primary bandpass....1.25” size = $49 (SOLD)
.......(similar to Thous. Oaks LP-4 @ $89-$179)..........48mm size = $69 (SOLD)

**NARROWBAND "UHC"-TYPE: I also have a few of these type, with nice transmission graphs (see pix below). About 28nm passbands, for $50 each.

**BROADBAND "DEEPSKY"-TYPE: I have one of these in the 48mm size, with nice transmission curves. About 50nm bandpass (significantly better than Orion's Skyglow at 85nm bandpass), for $40. -- SOLD

Contact me if you're interested in either of these.

I prefer payment via PayPal (no fee), but I’m flexible. CONUS shipping is INCLUDED; additional cost for outside CONUS and Canada or Mexico. Thanks for your interest!
