The Askar 203APO is one of the largest apochromatic refractors from series production - a powerful refractor for your observatory
This reducer effectively shortens the exposure time and significantly increases the field of view.
This flattener is designed for the Askar 103APO and corrects curvature and coma.
The Askar 120APO is a 120 mm aperture, 840 mm focal length, and f/7 native focal ratio apo refractor with many useful features and two corrector options.
Specially designed for the Sky-Watcher Skymax-200DX Maksutov Cassegrain, the Focal Reducer/Flattener consists of two lenses and has a reduction factor of 0.7x, resulting in a fast telescope with an aperture ratio of f/7.
Facilities:
200mm (8”) f/2000 Aplanatic Maksutov-Cassegrain Telescope
The new, highly impressive Sky-Watcher Skymax 200DX Maksutov Cassegrain telescope is a premium 200 mm f/10 aplanatic optical system, built for experienced astrophotographers and visual observers who want exceptional sharpness, maximum contrast and a uniform flat field across the entire image circle.
Note: The recommended PWM value is around 80. When the temperature of the heating belt is 5 degrees higher than the dew point temperature, it will stop heating. When the temperature drops, it will automatically heat up.
