That's very nice. All DIY efforts to make visual astronomy more accessible are more than welcome as consumer products are priced for the global market.

My telescope(s). It's a very rewarding hobby, from making the mirror (manual labor + measurements with interferometry), silvering it (a bit of chemistry), designing in CAD and building the actual usable telescope, there are a lot of mo

You must be right, there also must be mechanical steps or wobble at play here. I was hesitant because my 3D printer (lower-end than an Axidraw) seems capable of smoother angled/curved lines than what we can see here. On the other hand

A printer will usually leave a dot pattern to reproduce shapes, with a resolution fine enough that everything will be sharply defined. The blackness of a laser printer is a bit less qualitative than ink, because it's shinier from a lar

Silvering mirrors is coming back in fashion, either with the old recipe à la Jean Texereau / How to make a telescope, or with a spray silvering process. This week I silvered my last mirror with spray silvering, which was quite economic

I am currently building a tiny language designed only for data manipulation in a long-term personal project : data made of number/strings/booleans in maps or lists goes in, can be re-shaped, and goes out. It's written in Type

This is only tangential to the point raised by the article, but I encourage anyone interested to try to make and measure a mirror, it's a really rewarding process to take a round slab of glass to an almost perfect parabolic surface (or
