Versatility: Suitable for SCTs, Maks, or refractors with focal ratios from F/15 to F/30. Plug-and-play usability; simply insert into the diagonal with an eyepiece.
Safety for SCT and Mak Users: Requires an Energy Rejection Filter (ERF) specific to the telescope for safe operation.
Optimal Performance for SCTs: Must use a front mount, off-axis, aperture reduced ERF for heat prevention and optimal performance.
Maktsutov Requirements: Suitable for ~F/15 focal ratio without aperture reduction, but requires front mount energy rejection.
Filter Bandpass: Varies based on telescope application; qualified for prominence or surface (chromosphere) viewing. No specified FWHM bandpass.
Design Efficiency: Fully optimized, eliminating the need for adapters. Lightweight and eyepiece-sized.
Compact and Cost-Effective: Reduced components and costs, with added baffles for increased contrast and optimized AR coatings for 656nm wavelength.
Power Consumption: Low, capable of operating all day on an optional small battery pack.
Compatibility Warning: Not for use with full aperture SCTs to avoid secondary mirror damage.
Connection: Front, male 1.25" eyepiece snout with safety indent, 2° off-axis adapter included.
Output and Accessories: Standard rear female 1.25" drawtube with optional 2" accessories.
Protection and Power: Brass compression ring for eyepiece protection, USB power (5v, 1.5amp), includes 90-240VAC wall adapter with international plugs.
Tuning and Warranty: Tuning knob for wing shifting +/- 0.5Å, 5-year warranty.
Use: 0-power filter, no barlow lenses or focusing elements included.
Viewing Capabilities: Best with F/15 - F/30 refractors or Mak's full aperture; or SCTs and Maks with off-axis, aperture reduced ERF. Full disk viewing on refractors up to ~1800mm focal length.
No Aperture Limitations: Suitable for larger refractors for higher magnification.
Storage and Battery: Ships in a Twist-Case for storage, optional 8-hour battery pack available.
