USED - IDAS NB1 Z filter

I was worried buying used, but this filter arrived in excellent shape with no scratches. It screws onto my ASI camera perfectly and the triple passband really cuts through light pollution.

Wasn't sure what to expect buying used, but the glass came clean with no scratches or haze. Screwed right onto my M42 camera and the triple passband is doing exactly what I hoped for with the nebula shots. Condition was honestly better than described.

Picked this up used and honestly can't tell it was ever opened. Threads onto my M42 camera cleanly, and the triple passband really tightened up the halos on my emission shots. For the price of a used one, this was a no-brainer.
