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, Solar Filter for the Skymax-127 and C5, Solar Filter for the GSD 680, and Mercury Transit 2016.
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.
The filter has to be carefully mounted to the telescope, so that the film will not be dented by any airlocks.
