Product Description
Simplicity meets performance in our all new no compromises 100mm Hydrogen Alpha solar telescope. This integrated solar telescope offers safety and ease of use to show prominences, solar flares, active regions, chromosphere, spicule, and many more exciting phenomena visible in red Hydrogen Alpha light. With changes on the Sun visible after only a few minutes, each day will bring fresh new views never to be repeated.
Not Just a Quark in a 100mm Telescope!
Daystar's clean sheet design improves upon the great value and versatility of the Quark.
- Truly Dedicated and Integrated: The barlow of the Sol 100 is the actual drawtube of the focuser, complete with brass focusing rack. This conjoinment makes the assemblage of components on the rear of the telescope tighter and more compact with no wobble from adding components into a drawtube. The Quark IS the drawtube.
- The Quark can’t be accidently removed during outreach events by an unsuspecting curious child. Not only is the etalon cup bolted to the telescope, but the barlow and blocker are integral components deep in the structure of the instrument. The Sol 100 can’t be unsafe and a telescope at the same time.
- Lenses were all prescribed and optimized as a cohesive unit for h-alpha. This allowed us to achieve the parallelism required for narrow bandpass at the etalon at a faster focal ratio. Etalons require near parallel light to deliver best performance. Clean sheet telecentric lens design accomplishes this at a faster focal ratio.
- Full Disk with 100mm. Lots of astronomers want a full disk through their solar telescope. This can be difficult to achieve with 100mm of aperture. This custom design delivers 0.75° field of view at 100mm aperture.
- Nighttime telescopes are designed and coated for full spectrum, where their design wavelength is 500 nanometers. The Sol 100 was designed and coated uniquely for the Hydrogen Alpha 656nm wavelength.
- No more wild focus shifts! When a barlow lens is used like the 4.3X which is in a Quark, focus becomes super-sensitive and the range of travel needed is 1/4 of the turns. That makes it possible to get hopelessly lost when trying to focus a regular focuser with a Quark mounted. Our Sol 100 focuser offers the full focus range between Visual with a 2" diagonal and an eyepiece – all the way down to a camera mounted directly on the Quark housing. But not so much as to get lost.
- The built-in solar finder embedded in the mounting rings means never having to mount or align an aftermarket solar finder. The solar finder dot is always collimated with the scope. Even if your rings are actually crooked! The finder is always aligned to the instrument.
