Solar Filter for Skymax-127 OTA and C5

Introduction

In order to also be able to observe the sun, I acquired a euro EMC solar filter for my Sky-Watcher Skymax-127 tube, namely the type SF100 filter (order no. 600-106, size 6: for tubes with a diameter from 129 to 157 mm, aperture = 120 mm). These filters utilize the Baader Planetarium Astro Solar film of density 5 (ND5), which is suitable for both visual observation and projection photography.

Update: In the meantime, I sold my Skymax-127 - and bought it back later - and acquired a Celestron C5, which also fits this solar filter (see below).

Note: The filter has to be carefully mounted to the telescope, so that the film will not be dented by any airlocks.

The filter comes with a small Allen wrench to tighten the filter holders. It must be noted that the disc-shaped sun visors have to fit properly, so that no sunlight can penetrate through any slots.
