Amazingly useful filter can be used visually for Nebulae..even on Jupiter or Mars, some use for AP Even....GREAT CITY FILTER ! Excellent condition used sparingly.
$69 posted FIRM in Oz...CLS... CITY LIGHT SUPPRESSION..GREAT if near streetlights...Fantastic on The Ring ,Triffid, and Lagoon nebulae etc...FAR BETTER then cheaper Ebay filters!
SCRATCHPROOF COATINGS.
