Overview

The wait is over!!! MLAstro 10mm Quartz Slit is the extended-length upgrade for the SHG 700, built for solar spectroheliographers who want to capture the entire Sun in one pass on longer focal length telescopes. Designed with a premium heat-resistant quartz substrate and MLAstro’s OD7-rated coating (on VIS), this slit can now handle unfiltered scopes up to 130 mm aperture at f/7 or slower. To achieve this, we need a complete rethink of the slit coating/lithography process and even the glue that attaches the slit to the slit mount has to be beefed up too.
