Sun spot spotting

Posted by Patric on

Sun spot activity currently ramping up. Time to take out the telescope and go for some early evening sun spotting from the balcony.

A note of WARNING and DISCLAIMER: only use certified sun filter foil, I am using Seymour Solar Filter, grade ND5, available here. Be responsible and operate on your own risk.

Telescope equipped with 3D printed sun filter, maximum telescope diameter 183mm.

Filter assembly, 2 support rings, 2 screw on covers to protect the delicate filter foil (!!safety item!!)
