Daystar Instruments SODIUM Quark filter
The Sodium Quark brings quick, easy fun of the Original Quark to Sodium D-Line.
For use on refractors of F/4 - F/8 focal ratio refractors.
This All-In-One design marries high quality components of adapters, snouts and Daystar Sodium filter into one simple assembly. Through design efficiency and optimization, now users can enjoy the known high quality optics of Daystar at an affordable price.
Sodium will give high resolution sunspot detail, plague, granulation, and possibly the super-granulation depending on resolution and seeing of the observer.
Sodium can also show flare footprints, also known as flare kernels.
That is that a flare will begin and emit light in Sodium at the 2 ends first, before erupting in white light.
The line is brighter than both Calcium and even Hydrogen Alpha. So it's going to be very easy for observers to see and the exposures will be very short.
We'll be doing D2 line on 5890
Sodium D line Quarks will all be 0.5 or narrower.
-
For use on F4 - F/8 focal ratio refractors, the user needn't worry about configurations. Just insert in your diagonal, add an eyepiece and view.
- Exact filter bandpass will vary based on final telescope application. No specific FWHM bandpass is designated, but it will be around 0.5Å or lower. The fully optimized design eliminates the need for any adapters. It's all combined in one lightweight eyepiece sized device.
- The new, compact design configuration eliminates unnecessary components, weight and associated costs. We even reduced power consumption, so the Quark can now operate all day off a small, palm-sized optional battery pack.
-
Compatible with yellow glass ERFs offered by Daystar. Red glass ERF filters will not pass Sodium. Daystar also recommends use with a UV/IR cut filter for safety. Users need to purchase an Energy Rejection Filter specific to their telescope for safe operation.
- Baffles have been added to increase contrast and AR coatings are optimized for the 589nm wavelength. We even reduced power consumption, so the Quark can now operate all day off an optional small, palm-sized battery pack.
