The Askar 80ED 80 mm f/7 APO tube is the manufacturer's entry-level model, making it a good choice for both visual observers and those new to astrophotography.
The central element of the product is the 80 mm diameter two-element ED lens optics, which minimizes chromatic aberration and provides excellent contrast. The 560 mm focal length allows for detailed observations while keeping the telescope easily portable.
Two types of reducers are available for the Askar 80ED 80 mm f/7 APO tube. The 0.85x reducer decreases the resulting focal ratio to f/5.95, while the 0.7x reducer transforms the telescope into an extremely fast f/4.9 optic. These reducers provide APS-C size optimized photographic performance, making them a perfect choice for beginner and advanced astrophotographers.
The telescope is equipped with a dual-speed rack-and-pinion focuser, allowing for precise and fine adjustments, ensuring the sharpest images. The Askar 80ED 80 mm f/7 APO tube stands out in the market not only with its technical specifications but also with the user experience it offers.
