By popular demand, we are introducing a Sodium D line version of the Quark, for use in refractors F/4-F/9. Sodium gives outstanding views of active regions, plage, and granulation, in a pleasing yellow/orange color. The Sodium D wavelength is 5890.0 or 5895.9Å
This new, All-In-One design marries Fabry Perot etalon technology with high quality components of a telecentric barlow, adapters, snouts and Daystar Sodium D line filter into one simple assembly. Through design efficiency and optimization, now users can enjoy high quality DayStar optics of at an affordable price.
For use on refractors of F/4 to F/9, the user needn't worry about configurations.
An ERF or Energy Rejection Filter is strongly recommended on front of your diagonal. (Please see options when ordering). For apertures above 115mm a special Sodium-Compliant (Yellow) front mounted ERF assembly is required, before your objective lens, please contact us to discuss options.
For normal use with refractors under 115mm, just screw the 2" ERF on the front of your diagonal, insert the Quark into your diagonal, add an eyepiece and view - or image with your Hypercam.
The QUARK contains a custom Daystar Instruments 4.2X telecentric barlow lens fully optimized in coatings and optical design. This highly specialized telecentric lens offers superior field flatness. Exact filter bandpass will vary based on final telescope application. No specific FWHM bandpass is designated, however the etalon will be approximately 0.3-0.5 angstroms. Now observers can buy a filter based on their desired observing goals instead of their budget. 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.
