DayStar Sol Series 100mm Dedicated Solar Telescope - Chromosphere

 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 500nm. 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 extra 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 rings means never having to mount or align an aftermarket solar finder. The solar finder dot is always collimated with the scope.\

The SOL100C is a dedicated solar telescope optimized for viewing solar filaments, spots, flares, and other rich details of our Sun’s chromosphere. The key that unlocks access to these otherwise obstructed details is the fully integrated DayStar Quark! As photons traveling from our Sun reach the 100mm primary objective, they first encounter a thin film of optical coating designed to narrow in on the Hydrogen Alpha 656nm wavelength. Next, they pass through an internally mounted blocking filter which attenuates the energy from our closest star. Then, they enter the first element of the 4.3x telecentric Barlow, which “re-parallelizes” the light, priming the photons for the thermally tuned etalon. This ultra-narrow Fabry Perot etalon sits in an electronically heated chamber, which is precisely tuned to center the bandwidth, allowing only a narrow (0.5Å) slice remaining transmission to exit and produce a delicate view of our Sun’s chromosphere!

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.
