Description
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.
Features :
- Optical Tube
- 80mm aperture
- f/17.5 focal ratio
- 1400mm focal length
- Refractor-style optical configuration
- Achromatic doublet lens design corrects spherical and chromatic aberration to produce accurate color fidelity without distortion across the entire field of view
- Sturdy and precise helical focuser has no backlash and won’t rotate eyepiece/imaging rig
- Carbon fiber optical tube reduces weight without sacrificing strength, and resists the expansion/contraction caused by temperature fluctuations which can cause internal lenses to move out of alignment and affecting image quality and focusing ability
Other Details:
- Prominence Quark
- Hydrogen-alpha bandpass
- Integrated 12mm blocking filter
- 22mm clear filter aperture
- Tuned to 0.5-0.3Å for viewing prominence details
- Tuning knob allows for ±0.5Å wing shift for Doppler-shift compensation
- Markers at every 0.1Å for reference and repeatability
- LED indicators for power, warming, ready, and fault
- Integrated 4.3x Barlow lens
- Two-element telecentric lens design keeps light waves parallel to flatten the field of view and reduce parallax as magnification increases
- Combination 2″ & 1.25″ snout — accepts 1.25″ eyepieces and accessories
- Can be moved to other OTAs
