Daystar Filters put together the 480E 80mm Refractor Telescope with Quark Prominence Filter Kit to provide you with a versatile instrument for nighttime astronomical and daytime solar observations. This bundle comes with an 80mm achromatic doublet refractor OTA, the prominence-tuned Quark solar filter, and a 90° dielectric-coated mirror diagonal.

  • SolaREDi 480E 80mm f/6 Achro Refractor Telescope (OTA Only)
    An ideal grab-and-go OTA for astronomical or solar viewing, Daystar Filters' SolaREDi 480E 80mm f/6 Achro Refractor Telescope is engineered with an achromatic doublet lens system and fully multi-coated optics that work together to improve light transmission and to produce color-accurate images without distortion across the entire field of view. For solar observing, the 80mm objective represents the maximum aperture that is safe to use without a front energy rejection filter, and the simple refractor optical configuration also eliminates the need for a rear IR/UV filter, so all that is required is a rear solar filter like the Daystar Quark.

    An innovative hybrid focuser combines the stability of a rack-and-pinion with the precision of a Crayford-style to enable fast yet fine focusing while still being able to handle heavier rear-weighted loads as from large eyepieces, accessories, imaging/photography rigs, and/or solar filters. It is outfitted with a 2" drawtube for using larger visual accessories. The OTA is constructed from CNC-machined aluminum with a gloss-black anodized finish that resists scratches. This OTA is offered here without a mount and tripod, but comes with a Vixen-style dovetail plate to easy attach to a wide variety of Alt-az, EQ, and motorized mount and support systems. To protect your investment during transport or in storage, the 480E comes with a hard aluminum carrying case.

  • QUARK H-Alpha Eyepiece Solar Filter (Prominence)
    Daystar Filters designed this version of the QUARK H-Alpha Eyepiece Solar Filter specifically for viewing prominences. 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.

    This all-in-one hydrogen-alpha filter is engineered to eliminate unnecessary components which reduced the size and weight, and enabled it to fit in a compact form factor that simply inserts into 1.25" or 2" diagonals and accepts 1.25" eyepieces. This design enables the use of nighttime telescopes for solar viewing. In addition to the tunable H-alpha filter, the Quark also functions as a 4.3x Barlow lens, with a 2-element lens system 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.

    While there are no OTA aperture limitations, Daystar recommends the use of UV/IR cut filters or front-mount energy rejection filters on OTAs over 80mm of for long-duration solar viewing sessions. For best results, they suggest using refractor-style scopes with focal ratios between f/4-f/8, and you can enjoy full-disk viewing with focal lengths up to 450mm. The filter is powered via a micro-USB port, and Daystar includes a power cord and an AC adapter to meet the high-power requirements of 5 VDC 1.5A. To enable its use at home and abroad, a set of international outlet plugs is provided with adapters for the US, UK, EU, and Australia.

    Filter Properties
    • Hydrogen-alpha bandpass
    • Integrated 12mm blocking filter
    • 21mm clear filter aperture
    • Tuned to 0.8-0.6Å for viewing prominences
    • 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
    Optics
    • Integrated 4.3x Barlow lens
    • Lens and optical coatings designed specifically for 656nm H-alpha wavelength
    • Two-element telecentric lens design keeps light waves parallel to flatten the field of view and reduce parallax as magnification increases
    Recommended OTA Specifications
    • No aperture limitation
    • Best performance with f/4-f/8 refractors
    • Full-disk viewing on refractors up to 450mm focal length
    • For apertures over 80mm (3.1"), or for long-duration solar viewing, an UV/IR cut filter should be used for energy rejection
    • Not suited for off-axis applications
    Power
    • 5 VDC, 1.5A micro-USB port
    • 90-240 VAC wall adapter
    • Set of international outlet plugs for US, UK, EU, and Australia
