A magnetic solar filter for the Mak 127

Designing and 3D printing a solar filter for the Sky-Watcher Mak 127, with Baader AstroSolar film and a magnetic quick release so it comes off during the 2026 eclipse without touching the telescope.

An intervalometer with the Raspberry Pi: getting ready for the 2026 eclipse

A home-made intervalometer for the Sigma fp, built with a Raspberry Pi, for the timelapse of the total solar eclipse on 12 August 2026. It also works with the Nikon D5600, and can be adapted to other cameras with help from AI.
