Description
This new, All-In-One design marries high quality components of adapters, snouts and Daystar hydrogen alpha 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.
For use on 3.5" Classic QUESTAR Maktsutov telescopes. The user needn't worry about configurations. Just thread the QUESTAR Quark in either port, add an eyepiece and view.
• QUESTAR users need to purchase an Energy Rejection Filter specific to their telescope for safe operation.
• Exact filter bandpass will vary based on final telescope application, so QUARK assemblies are qualified to show either prominences or surface (chromosphere). No specific FWHM bandpass is designated. Either model are available for the same price.
• Now observers can buy a filter based on their desired observing goals instead of their budget. Choose prominences and surface (Chromosphere) detail. Both are available for the same low price! 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.
• Baffles have been added to increase contrast and AR coatings are optimized for the 656nm wavelength. We even reduced power consumption, so the Quark can now operate all day off an optional small, palm-sized battery pack.
Not for use with full aperture SCTs, or damage to your secondary mirror may result. SCTs must use an off axis ERF, sold separately.
*The QUARK* assembly is a product of DayStar Instruments, using DayStar Filters' Fabry Perot etalon technology.
