SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

DayStar Filters SS80P overview

  • 1Description

Study the rich details of the sun's prominence using Daystar Filters Solar Scout 80mm f/17.5 H-alpha Achro Solar Telescope. Optically, this is an achromatic doublet refractor which corrects spherical and chromatic aberrations to produce accurate color rendition without distortion across the entire field of view. Included with the optical tube assembly is the Quark solar filter system, specifically tuned for prominence viewing. Prominences, a detail of the chromosphere projected against the blackness of space behind the sun, are seen with improved contrast due to the filter's narrower bandpass versus a wider bandpass filter tuned for conventional chromosphere surface viewing.

The Quark is an all-in-one hydrogen-alpha filter engineered to eliminate unnecessary components, which reduces the size and weight and enables it to fit in a compact form factor that simply inserts into drawtubes and accepts 1.25" eyepieces. In addition to the tunable H-alpha filter, the Quark also functions as a 4.3x Barlow lens with a two-element lens system that is designed to be telecentric, which flattens the field of view and reduces parallax, and optical coatings that are optimized for the 656nm H-alpha wavelength. This design enables the use of nighttime telescopes for solar viewing, so it can be removed from the Scout OTA and inserted and used in many traditional telescopes.

The Solar Scout is offered here as an OTA-only option, so a mount and tripod are required for proper use. Daystar includes a Vixen-style dovetail plate to be compatible with many mounts, and a 1/4"-20 mount on the plate allows it to be directly attached to many photo, video, or field tripods. Also included is a solar finder for safe alignment for observation, and a hard carrying case to protect it when it's not being used.
