The Calcium Quark brings fast, simple enjoyable of the Authentic Quark to Calcium H-Line.
To be used on refractors of F/7 or longer focal ratio refractors.
This All-In-One design marries top quality elements of adapters, snouts and Daystar calcium filter into one easy meeting. By way of design effectivity and optimisation, now customers can benefit from the recognized top quality optics of Daystar at an reasonably priced value.
Essential: To forestall harm, we advocate utilizing an Vitality Rejection Filter on telescopes of 80mm aperture or extra, or when monitoring the Solar for lengthy intervals. This is usually a UV/IR minimize filter mounted earlier than the diagonal. For apertures over roughly 150mm 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.
Options
Why H-line?
Many astronomers neglect that the Calcium H-line and Ok-line yield nearly similar views of the Solar. Photo voltaic researchers who solely picture the Solar with CCD cameras typically select the Ok-Line for purely analysis functions. Sadly, with Calcium Ok-line filters, many older astronomers are unable to see the decrease wavelength and miss out on all of the enjoyable. We provide greater wavelength Calcium H-line filters for visible observers so that the majority shoppers can get pleasure from Calcium!
Refractors
REFRACTORS: For transient 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 below roughly 150mm 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 subject flattener or Petzval lens. The UV/IR minimize filter have to be the primary optical factor to come across concentrated mild.
Notice that Calcium 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 150mm of aperture requires consideration of a number of elements please contact us for recommendation.
