Hey all,

I'm also looking to part with my trusty ZWO narrowband filter set. This is the 36mm diameter, 7nm bandpass set that includes all three (Sulfur-II, Hydrogen-Alpha, and Oxygen-III) filters. They're in mint condition with no scratches or flaws on the optics.

Price for the set is $300, but willing to drop that to $275 for any members of the club. They're a great way to get into narrowband imaging without the cost of the big names. 

Check out my Astromart post for the original listing. https://astromart.com/classifieds/astromart-classifieds/filters/show/36mm-zwo-sii-ha-oiii-filter-set

Thanks!
