I built a Hadley, and it's pretty amazing. I have seen the rings of Saturn with it- and the moon- WOW. Here's a video I did about it:

Also wrote it up on my website, which has a link to the Hackaday article I wrote on it: https://miscdotgeek.com/3d-printing-the-hadley-114mm-newtoni...

I still need to build a proper base for it. Balancing it on a chair or some other thing is just no good. It needs to move smoothly. What you think you know, don't realize how pronounced it is until you're watching through a decent telescope, is that the cosmos are on the move!

I see you wrote you used PETG - would you recommend it, or would you have done it again in PLA?

(due to accuracy.)

		It worked fine, no regrets. It's more stable for outdoor use, so that is why I went with it. I've printed exclusively with PETG.
