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

Note: In January 2019, I sold the EMC Sun Filter SF 100, order number 600-107 (size 7), together with my Sky-Watcher Explorer 150PDS Newton tube. I am therefore regrettably unable to report any further experiences with the filter size 7 on this site.

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.
