Set of 5 x 50mm SBIG round, unmounted filters: Luminance, Red, Green, Blue and Clear.
Purchased with QHY9 camera on IIS in 2009. I presume these are the same as shown here:
www.astronomics.com (https://www.astronomics.com/research-series-2-rbg-c-l-filters.html)
They are in great condition as have been in storage while I have been using other filters.
$250 plus postage.
