These are new, high quality Astrodon Sloan Photometric filters that are being closed out because they are 1st generation, odd sized, left overs from special orders, etc. So here is your chance to score some bargains!

NOTE: In Astrodon part numbers we pronounce the ‘ character (apostrophe)  as “prime” and the _ character (underscore) we pronounce as “sub”). So u’2_27R should be read as “u prime 2 sub 27 R”.
