Discover extremely magnetised and highly effective excitations within the vivid Magnesium I (b2) line.
To be used on refractors of F/4 – F/8 focal ratio refractors.
This newest and sure the final wavelength supplied for Quark reveals an entire new space of extremely magnetised excessive power within the vivid 5172.8Å wavelength. The attention is most delicate at this wavelength so the picture is considerably brighter than calcium. Views present each plage and darkish mottling of chromospheric community.
Necessary: To stop harm, we advocate utilizing an Power Rejection Filter on telescopes of 80mm aperture or extra, or when monitoring the Solar for lengthy durations. This generally is a UV/IR minimize filter mounted earlier than the diagonal. For apertures over roughly 120mm requires consideration of a number of elements, please contact us for recommendation.
*The QUARK* meeting is a product of DayStar Devices, utilizing DayStar Filters’ Fabry Perot etalon know-how.

Why Magnesium I (b2)-line?
Magnesium is a extremely magnetised chemical on the solar. The temperatures for energetic exercise emitting this line are calculated to be extraordinarily excessive. Spectroscopically, a line “splitting” known as the Zeeman impact could be noticed, whereas the darkish absorption “splits” and happens barely above and under the standard wavelength the place mild from non-magnetised exercise is absorbed. Robust absorption could be seen spectroscopically at 5172Å.
Views in Magnesium reveal plage, massive scale magnetic construction and darkish absorptive mottling of the chromospheric construction. The road is brighter than Calcium, Hydrogen Alpha and even Sodium. So it’ll be very straightforward for observers to see and the exposures shall be very brief.
The MgI b2 strains are a triplet. Our goal is the center, 5172.8Å line.
Magnesium I b2 line Quarks will all be 0.4 or narrower.
Refractors
REFRACTORS: For temporary observing classes utilizing refractors with lower than 80mm of aperture when not utilizing a monitoring mount, no rejection is critical. Be alert for any rise in temperature of your telescope, diagonal, or Quark.
For telescopes underneath roughly 120mm of aperture, a screw in UV/IR minimize filter could be employed in entrance of the telescope diagonal. The UV/IR minimize filter displays UV and IR mild again out the entrance of the telescope, decreasing temperatures inside.
Don’t use a UV/IR minimize filter with a telescope with an built-in rear discipline flattener or Petzval lens. The UV/IR minimize filter have to be the primary optical factor to come across concentrated mild.
Notice that Magnesium falls exterior the passband of some UV/IR minimize filter designs, so at all times confirm {that a} potential UV/IR filter passes 397nm earlier than buying.
Observing with over 120mm of aperture requires consideration of a number of elements please contact us for recommendation.
