Hi
I have a Baader Neodymium Moon and SkyGlow Filter with IR Blocker to fit a 1 1/4 inch eyepiece. As new. Hardly used. Well looked after.
Part Number # 245 8305A
I bought this 12 months ago, when I had a reflector, by the time it arrived I had sold the reflector, and it did not have much effect on the view through my SCT, so this has had little to no use.
Comes with original filter container in original box with documentation.
A Bargain at $45 (+postage) or pick up Central Coast / Newcastle / (Lostock this weekend - weather permitting)
PM me if interested
The Blurb:
Planeoptically polished and MC-coated with IR-Cut
Drastically improved contrast for all reflector telescopes, without loss of brightness!
Filter brings an entirely unique approach to contrast enhancement and light pollution reduction. Based on earlier research at Carl Zeiss, Baader has developed a new filter that uses Neodymium glass which filters out a few specific wavelengths from streetlights as well as skyglow from the Moon. The unique spectral characteristics of Neodymium also boost color contrasts by isolating the Red, Green, and Blue regions (so-called RGB enhancement). The result is a filter that leaves natural colors intact, but enhanced.
Lunar and Planetary views are improved in reflector type telescopes and true Apochromates.
Background sky is darkened, and subtle details improved. The filter's high efficiency preserves image brightness, and many Galaxies, Nebulae and Globular Star Clusters are improved due to the reduction of skyglow from artificial lighting.
Ultrahard and durable ion-beam hardened coatings
etc etc
