Product description A Buying Guide for Solar and Solar Eclipse Viewing Read More Designed specifically for Questar telescopes, but similar to their standard Quark, Daystar Filters' Questar Quark H-Alpha Eyepiece Solar Filter is outfitted with Questar-specific eyepiece and rear port threads to install quickly and easily, without adapters, directly into your OTA.This all-in-one hydrogen-alpha filter is engineered to eliminate unnecessary components which reduced the size and weight, and enabled it to fit in a compact form factor that simply threads onto either port and accepts standard 1.25" eyepieces. It is tuned specifically for viewing prominences. Prominences, a detail of the chromosphere projected against the blackness of space behind the sun, are seen with improved contrast due to the filter's narrower bandpass versus a wider bandpass filter tuned for conventional chromosphere surface viewing. While there are no OTA aperture limitations, Daystar recommends the use of front-mount aperture-reducing off-axis energy rejection filters. The filter is powered via a micro-USB port, and Daystar includes a power cord and an AC adapter to meet the high-power requirements of 5 VDC 1.5A. To enable its use at home and abroad, a set of international outlet plugs is provided with adapters for the US, UK, EU, and Australia. - Filter Properties
