Askar FRA300 Pro – 60mm f/5 Petzval APO Refractor with flat field for wide-field astrophotography

The Askar FRA300 Pro is a Petzval apochromatic refractor designed to offer high performance in wide-field astrophotography, even with full-frame sensors. With a 60mm aperture, 300mm focal length (f/5), and a quintuplet optical design with an ED lens, it guarantees sharp images, accurate colors, and a flat field. The tube is compact and lightweight, ideal for portable setups, travel, and deep-sky exposures, without sacrificing optical quality and detail.

• Quintuplet (5-element) Petzval optical design with an ED lens to reduce chromatic aberrations
• Flat field of view compatible with full-frame sensors (image circle of approximately 44 mm)
• f/5 focal ratio – perfect for faster exposures on large deep-sky objects
• 2.5" rack-and-pinion focuser with 1:10 micro-adjustment for better focus control; integrated 360° rotator
• Multiple rear threads: M42, M48, M54 for accessory compatibility
• CNC aluminum body, robust tube, 2.26 kg weight for the OTA (3.12 kg with rings, dovetail bar, and accessories)
• Compact tube length (~303 mm) for increased portability
