Checking back on the receipt it says "new" in the title which is making me think they are not 1st gen but the packaging doesn't say anything. Just thought I would mention it.
Local price brand new $250
Direct from ZWO $240
Selling for $140 shipped.
Also have an H-Alpha filter purchased off a friend of mine. Have used it once and got some real nice results. I was told it was 12nm but the box it came in is ZWO 7nm 31mm and there is real no way of knowing.
