Users need to purchase an Energy Rejection Filter specific to their telescope for safe operation. Daystar also recommends use with a UV/IR cut filter for safety. Red glass ERF filters will not pass Sodium.

The fully optimized design eliminates the need for any adapters. No specific FWHM bandpass is designated, but it will be around 0.5Å or lower. To use the filter, plug in the included power supply, then place the Quark after your telescope’s diagonal and insert an eyepiece or camera in the rear of the filter. I would like to here from people who have pu. Unfortunately, most of these reviews/posts seem to be from around 2015 - 2016.
#Daystar quark manual
Please read this manual before using the product. Hi All, I am considering purchasing a Daystar Quark Chromosphere, but having researched the forums, including SGL, it seems though there are or were a lot of quality issues. Exact filter bandpass will vary based on final telescope application. DAYSTAR FILTERS QUARK Congratulations on your purchase of a Quark Hydrogen Alpha Eyepiece solar filter.Just insert in your diagonal, add an eyepiece and view. For use on F4 - F/8 focal ratio refractors, the user needn't worry about configurations.We'll be doing D2 line on 5890 Sodium D line Quarks will all be 0.5 or narrower. So it's going to be very easy for observers to see and the exposures will be very short. The line is brighter than both Calcium and even Hydrogen Alpha. That is that a flare will begin and emit light in Sodium at the 2 ends first, before erupting in white light. Sodium can also show flare footprints, also known as flare kernels. Why Sodium D-line? Sodium will give high resolution sunspot detail, plague, granulation, and possibly the super-granulation depending on resolution and seeing of the observer.
