For Sale: Hutech IDAS LPS-P2 67mm (2") Filter . LPS = Light Pollution Suppression. I used this for visual observing and some astrophotography here in the *very* light polluted skies. It helped for sure. The filter has a hairline imperfection - 1/8" long, 1/2" from the outer edge. I never knew it was there until I inspected it for this sale. It is reflected in the price.
I will pick up PayPal and shipping (to the US).
Thanks for looking.
