Description
From the sellerFantastic filters, top quality. These are mid-narrowband (15nm H-alpha, 15nm S-II, 35nm O-III) The C1 filter is H-Alpha and O-III combined like the Optolong L-Xtreme. The C2 filter is S-II and O-III like the Optolong L-Synergy. Together the cover the Hubble H-S-O bands and can create images like the two I have shown here. A very cost-effective way to take your astro imaging to the next level. In excellent, barely used condition, no scratches. I'm selling because I have switched to a monochrome camera system, and these filters are for color cameras. Retail price for the set new is $225. Get a great deal here.
