Askar 80 mm f/7.5 APO AstrographWith the PHQ series Askar has developed flatfield apos, where the imaging quality on the axis and in the field is paramount. The focal ratio is moderate, but the stellar imaging is excellent. The 80 mm PHQ offers magnifications up to over 200x with good contrast.
The Askar 80PHQ is a real all-rounderThe transportable telescope can be used for almost all areas of amateur astronomy and offers a very good optical performance.
- Deep sky astrophotography with 600 mm focal length and a very large corrected field of view. Everything from high-resolution cameras with fine pixels to full-frame cameras can be used.
- Easy to use - just focus and you are at the optimum distance for very good field correction.
- Planetary and lunar photography, due to the very good correction of the optics on the axis and in the field, sharp and high-contrast images are achieved, even with focal length extension.
- Visual observation, the generous working distance also allows the use of 2" accessories.
The photographic 3" rack & pinion focuser:The CNC focuser is optimized for photography and can handle a load of up to 8 kg. The travel range of 110 mm is very generous. The drawtube is adjusted via rack-and-pinion drive. The drive is decoupled from the bearing of the drawtube. This guarantees fine and precise adjustment even at maximum load. In addition to the 1.25" and 2" receptacles, the focuser also offers threads for screw adaptations.
So we hand over the apo to the amateur astronomer:Each individual AS80PHQ quadruplet apo is inspected in our technical department before being stored to guarantee consistently high product quality.
- The mechanics are tested, the focuser is optimally adjusted.
- The objective is cosmetically checked and cleaned. In addition, it is checked whether all counter screws are correctly tightened. Often these loosen during transport.
- The optics are collimated and the result is checked on the optical bench.
- Only then are the telescopes transferred to the warehouse and prepared for shipment.
