First serious project kicks off. A 60mm f1.33 (fl 800mm) achromatic refractor telescope. Got the objective lens from Aliexpress for $12.32. Tube is 2 cardboard tubes from Saran Wrap rollls from recent move. Step 1: half of the thing to hold the lenspic.twitter.com/9rzVdPdSg3

The Aliexpress page has some very unclear instructions and talk about blue tape and green film. The package only came with the 2 lenses. No film. Unless they mean coating. Gonna have to figure this out. Tips and suggestions welcome.pic.twitter.com/AhALqq3X7q

I’m assuming dangerously that this will work with or without cementing. Gonna do experiments with the eyepieces I have first to make sure I have actual telescope optics going before finishing the mechanical design.

For mount, I plan to design something that will attach to a standard camera tripod. If this thing works out, I should have something similar to a typical small, cheap entry-level refractor. The kind that you can get at Walmart for $80-120. But for ~$40-50 in materials.
