The Altair ASCENT80mm F7ED Refractor Geared Focuser is a versatile telescope with Genuine ED optics that allows both visual observation and wide-field imaging. Featuring an 80mm objective lens, this refractor provides improved color correction for high-contrast images and comes in a short, portable tube.

Key Features:

Genuine ED optics for superior color correction and contrast
All-metal construction with no plastic parts (except for the rear dust cap)
Dual Speed Geared focuser with micro-focusing for fine detail
Imaging capable with a 2" Focuser push-fit adapter and brass compression ring
Optional 0.8x field flattener/reducer for flat-field, fast focal ratio imaging
Includes a 9x50 finder with a metal body and front focusing lens, along with a wide-field eyepiece with an independently focusing reticule
2"-1.25" Push-Fit Adapter with a non-marring brass compression ring
Retractable metal dewshield for enhanced portability
CNC machined tube rings for balance and rotation adjustment
Metal dovetail plate for compatibility with various telescope mounts

Advantages of ED Optics: Compared to small Achromatic refractors of similar size, the Starwave 80ED offers better mechanics for easier focusing and truer color rendition thanks to the ED optics. It delivers sharp, high-contrast images with good color correction and tight star images.

Versatile Use: The Starwave 80 ED is perfect for both beginners and astrophotographers. It's easy to use, requires minimal maintenance, and fits most telescope mounts. It's also suitable for terrestrial and nautical observation with the addition of an image-erecting prism diagonal.

Mount Recommendations: Recommended mounts include the Skywatcher EQM35, EQ5, and similar capacity mounts. Contact us for specific recommendations based on your observing style.

Magnification Guide: Use the eyepiece focal length to determine magnification. For example, the Starwave ASCENT 80ED with a 560mm focal length, when used with a 24mm eyepiece, yields 23x magnification. A Barlow lens can double the magnification.

Optional Accessories: Enhance your imaging experience with optional accessories like extension tubes, reducers, filters, and auto-guiding equipment. Contact us for advice on the best accessories for your setup.

Discover the night sky and delve into astrophotography with the Altair ASCENT80mm F7ED Refractor Geared Focuser, a high-quality telescope designed to provide excellent optics and mechanical quality at an affordable price.
