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…
With my suburban Winnipeg back yard getting brighter and brighter, I need to move my automated telescopes somewhere else that’s under dark skies. As part of that project I’ll be…
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…
By Gord Tulloch, published in the May/June issue of RASC Winnipeg Centre Over the past couple of years, I’ve tried a few techniques for getting auto-guiding working on my Celestron…
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…
