The Askar SQA106 is a quintuplet Petzval astrograph with a focal length of 509mm at F/4.8, featuring a 106mm aperture quintuplet air-spaced SD glass design with a 55mm image circle, making it an excellent choice for imaging with full frame cameras. This integrated flat field design requires no backfocus calculation and no separate field flattener, providing inherent flat fields perfect for full frame sensors. The telescope features a 360° high-precision rotator and a dual-speed 2.8-inch rigid rack-and-pinion focuser compatible with motorized systems, making it an ideal premium choice for serious astrophotographers capturing wide-field nebula imagery and deep-sky objects.
