Baader Solar Continuum Filter, a unique filter, transmitting a narrow 10nm bandpass around the 540nm region. The double stacked version is supplied with 20 x 29cm sheet of ND3.8 AstroSolar Photo Film.
Baader have made an IR cut filter that replaces the standard internal Canon filter. This filter has high transmission of the H-Alpha line and eliminates the cameras’ major disadvantage for astro-imaging.
The Baader Click-Lock 2 inch for Celestron and Meade SCT allows 2 inch eyepieces and accessories to interface with the smaller SCT thread used on all Celestron and Meade SCTs. It uses Baader’s innovative Clicklock clamping system that has proved time and again to save time, and wear and tear, on your eyepieces and accessories when changing them.
The Baader Fringe Killer Filter is a high quality UV/IR block which also removes violet and some blue light. Perfect for imaging and visual use with the smaller fast Chinese achromats and many semi-apos.
Midway between the Astronomik CLS and UHC in terms of bandpass, the Baader UHC-S Filter is best used visually by owners of smaller telescopes (8″ or less) for nebular observation or for general observation in areas of high light pollution.
Owners of larger scopes and imagers will get better results with the Astronomik UHC.
