ASKAR 0.75x REDUCER FOR 65PHQ Linear The Baader H-Alpha 20nm Bandpass

The Baader H-Alpha 20nm Bandpass filter is specifically designed for visual observation of faint emission nebulae under bright skies as well as imaging with colour CCD and CMOS cameras

or through the LX200 compatible protocol

the broad data base of these two surveys makes them very well suited for calibrating images

Also included in the complete kit is a high quality 2" low profile rack & pinion focuser with 11:1 fine focus control and integrated drawtube extension

ASKAR 0.75x REDUCER FOR 65PHQ Linear The Baader H-Alpha 20nm BandpassThe Askar 0. 75x Flattener Reducer for the 65PHQ is a 2. 5" corrector for full frame sensors. The flattener reducer is a quadruplet design with one element of ED (Extra low Dispersion) glass. The 0. 75x reduction factor shortens the focal ratio of the 65PHQ to f 4. 8, shortening the exposure time and increasing the field of view. When paired with this flattener reducer, the focal length of the 65PHQ becomes 312mm, transforming it into an extremely
