Very cool project and video documentation, really inspiring! As someone who is mechanically inclined and has a decent amount of tools/3D printer, is there any DIY telescope that you would recommend to build as a first foray into the field? I've never done much with optics, and after reading through a few of your posts, it looks both incredibly challenging and very rewarding.

To me, there are two models that stand out from the crowd : - The Hadley, a 4"1/2 f/9 dobsonian telescope, which is a smaller aperture but easy to build and to find optics for, and very mature : https://www.printables.com/model/224383-astronomical-telesco... - The "open smallest telescope" from a friend, which I show here, a foldable 6inch f5 dobsonian : https://lucassifoni.info/blog/2025-best-6-inch-f5-150-750-po...…

I will check them out! Thanks for sharing

Very cool, any pictures of the images it produces?

Sadly not as I exclusively practice visual astronomy. Here is a nebula, NGC7000, drawn by an excellent observer, which appears that way (very wide field, but a bit dimmer than their drawing) : http://www.astrosurf.com/magnitude78/serge/images/NGC7000_10... My advantage despite the low diameter is the ability to frame such huge objects !

What is ‘visual astronomy’? (Sorry, absolute noob here). Wait did you mean.. ‘non-visual astronomy’? I am really confused now

I believe he means that he does not do astrophotography. So no photos to share

Just go down the rabbit hole like I have over the past year... Find thick glass on Facebook, build a cutting jig, build a kiln to fuse it, etc. I'm still planning to build an 18".

Very nice, are you documenting this somewhere ?

No, it's nothing new. There are other projects that have documented these types of things better than I could.
