Printing Eyepiece Cases
Eyepieces need cases, but it’s expensive to buy a bunch of different sizes for different size eyepieces, particularly for 2” “hand grenade” sized eyepieces like the 18mm TeleVue Nagler and…

I seem to have a lot of Pyrex mirror blanks on hand and grinding it all into mirrors at the current size seems a bit of a waste. Most of…
UPDATE: I am now posting my 3D designs at: http://3.99.76.122/3d-printing-for-astronomers/ I have to say 3D printing is a mind blower. If you can envision it, work some easily learned 3D…
The design for the 24″ I’ve arrived at is based on the design in the image above (from an amateur in France), mounted on a trailer for easy transportation in…
I have a 24″ (609.6mm) diameter piece of unknown glass that weighs 72 lbs (32.6 kg) on the nose and is 2″ (50.8 mm) thick exactly. The ROC is 93″…
Since I have a couple of 6″ mirror blanks and need to get back into the mirror grinding groove for upcoming large telescope projects, I’ve started grinding a 6″ F/3.3…
My 16″ F/4.5 Telescope is pretty close to done – just have to mount the motors and belts, and test it all out. I built one set of electronics over…
Sorry no pictures of the actual scope but got a lot done over the Xmas holidays, all the major components are complete, just need to debug. I had an epiphany…
Before starting to grind my 24″ project down to a more reasonable focal length I decided to test the blank for strains within the glass that would prevent it from…
Finally got my FeCl and stripped the two mirrors I’ll be working on this winter – the 12″ is perforated so it was a pain putting a dam in the…
