Introduction

In order to be able to also observe the sun, I acquired a euro EMC solar filter for my Sky-Watcher Explorer 150PDS Newton tube, namely the type SF100 filter (order no. 600-107, size 7: for tubes with a diameter from 155 to 202 mm, aperture = 146 mm). These filters utilize the Baader Planetarium Astro Solar film of density 5 (ND5), which is suitable for both visual observation and projection photography.

Note: See also pages Solar Filter for the Heritage 100P and 114P and Skymax-102 OTA, Sun Filter for the GSD 680 and Mercury Transit 2016.

The filter comes with a small Allen wrench (see photo above right) 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.

Ditto. By the way: If you use the plastic protectors for the threaded columns, the filter just fits the tube with the columns outside the tube.

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