Daystar Camera Quark H-alpha Filter (Chromosphere or Prominence)
This new, Daystar Camera Quark Chromosphere turns ordinary Nikon and Canon SLR lenses into Hydrogen Alpha Solar Telescopes. Owners can view using their SLR or DSLR camera or an eyepiece. Camera QUARK accepts all of the universal QUARK accessories so it may be used as a telescope with an eyepiece. Plus! Use zoom features of your camera lens to explore wide field to high power views without changing set-up or telescope configuration.
Quark* is available in a choice of “prominence” or “chromosphere”.
Exact filter bandpass will vary based on final telescope application, so QUARK* assemblies are qualified to show either prominence or surface (chromosphere). No specific FWHM bandpass is designated. Now observers can buy a filter based on their desired observing goals instead of their budget. Choose fore WIDER prominences with a little surface or MORE surface contrast (Chromosphere) and narrower prominences. Both are available for the same low price!
For use on Nikon configuration or Canon configuration.
The patent pending QUARK* contains a custom Daystar Instruments 4.2X telecentric barlow teleconverter lens fully optimized in coatings and optical design specifically for the Hydrogen Alpha wavelength. This highly specialized telecentric lens offers superior field flatness.
The fully optimized design eliminates the need for any adapters. It’s all combined in one lightweight device. Quark* can now operate all day with optional small, palm-sized,battery pack.
*The QUARK* assembly is a product of DayStar Instruments, using DayStar Filters’ Fabry Perot etalon technology.
