[Utah-astronomy] Killer and cheap APO lens (Thought I would share)

180mm Nikon ED F2.8 MF (AIS) There are versions that are not ED. You can get beat up ones on ebay for under $200.00. Here are some test shots and some information on it. http://www.cloudynights.com/ubbthreads/showflat.php?Cat=&Board=DSLR&Number=3... Amazing fast, and flat field for way cheap. I got one off ebay for 180$ with the barrel scratched up and great optics still. This was also taken with one of these lenses. http://octane2.deviantart.com/art/The-Rho-Ophiuchus-Complex-59850107 If you looking for a great apo wide-field lens..this is it. Compare to the canon models. You can get a $15 Canon to Nikon lens adapter of ebay if you shoot canon. Cheers, David
