The Askar 60F 60 mm f/6.8 quadruplet APO tube is designed for astronomy enthusiasts and professional astrophotographers who desire impeccable optical and mechanical performance. This compact and ultra-portable telescope is an excellent choice for both visual and photographic purposes.
The Askar 60F tube, with a 60 mm diameter and 408 mm focal length, features a focal ratio of f/6.8. The color-corrected ED triplet objective and built-in field flattener lens ensure distortion-free, precise sharpness across the entire field of view. The telescope provides a 44 mm image circle, making it perfectly suitable for imaging with full-frame sensors. The system's advantage is that, similar to Petzval optics, there is no need to account for backfocus. With the optionally available 0.75x reducer, it becomes an extremely fast f/5.1 astrograph.
The dual-speed, 2.4" rack-and-pinion focuser allows for precise adjustments and can rotate 360°. The focuser features M64, M54, and M48 threaded connections, ensuring wide compatibility with various accessories and cameras.
Thanks to the practical tube ring, Vixen-style dovetail bar, and handle, the Askar 60F is easy to mount and transport. The telescope also includes two dovetail shoes for attaching additional accessories. The retractable dew shield helps protect the lenses from moisture and dew.
The Askar 60F tube weighs only 2.9 kg and measures 289 mm in length, making it ultra-portable and an ideal choice for trips or locations where easy transportability is crucial. The Askar 60F 60/408 quadruplet APO tube offers outstanding performance in quality optical solutions, making it an excellent companion for astronomical adventures.
