FLI PDF focuser. The PDF (Precision Digital Focuser) is a large aperture format with very high resolution. It comes with everything pictured, no adapters. I bought it on Astromart a couple years ago. Ive only been able to actually use it once. It worked well but I was on a mobile setup and one more thing to setup was a pain. Lately, I've been focusing on wildlife photography and no longer have time for Astrophotography. Looking to sell or trade for a long Nikon or Canon EFS/VR lens (500mm). Thanks
