An AZ-GTi can be bought more cheaply second-hand and a decent second-hand tripod (e.g. old Marantz, etc.) is usually sufficient for it. I bought my AZ-GTi for 250GBP with several extra after-market accessories and I've seen them cheaper in the UK since. The Marantz tripod I bought was about 35GBP a few years ago but I've seen others for sale since then. I'm using it with a Celestron C5 Schmidt-Cassegrain, Skywatcher Heritage 100P Newt and an Altair 70ED refractor. It's a very capable bit of kit. Your video is an excellent presentation of this telescope design, thank you. Not something I can build but hopefully encourages others into the hobby and it looks like a lot of fun.
Thanks for checking out the video. I recall looking for a used AZ-GTI back when I bought mine but couldn't find any and/or couldn't resist the Amazon Prime next day shipping lol.
Thanks for this Dave, I have just subscribed 🙂 I have been so impressed and inspired with your Hadley based design I’ve ordered the mirrors and started to print out your scope. Is there an easy way to change the 18mm rod tube size, say to 15mm, 19mm or 22mm. Carbon fiber rods expensive and are not easy to source where I live but 19mm steel or alloy tubing is. I downloaded FreeCAD but I have no experience using this or any design software. Regards Colin
@@designbydave Thanks Dave, I had a go on Tinkercad and printed out a 15-19mm adapter tube so I could use 15mm copper plumbers piping which is inexpensive and readably available here in Scotland. This works great and means I can still use your design. This combines two new hobbies 3D printing and astronomy for me in my retirement, SlangeVar Dave 🙂
This is a great remix! I went to your site to get the files to print the mount adapter rings but I don't have SolidWorks. Could you possibly create them in .STL format? I've already printed a Hadley telescope and am looking to mount it on my AZ-GTi. Thank you! EDIT: I just downloaded Fusion360 for personal use. Your project is my excuse to start learning it! Thanks again!
Thanks I include the STEP file instead of STL, since they are still parametric. Prusaslicer (and others?) can now import STEP so no need for STL sharing. STLs are limiting because they aren't as easily modified.
Is it possible to disassemble it in parts for travelling? As I wanted to make one, but I live where the highest bortle level is and wanted to go with a car to a place 3 hours away from me and I'm sure the telescope won't fit assembled in the car.
The assembled telescope is less then a meter long. I should think that will fit in all but the tinniest of cars. Yes it is possible to disassemble but the strut-tubes will still be the same length as the assembled telescope, unless you design them to breakdown, which would be possible.
A commercial 114mm f8 would be $150, on a cheap EQ-1 mount, would this be any more economical? More fun to make it yourself, I’ll give you that. But perilously close in price to the off the shelf version.
You are correct. I don't do projects to save money and, especially if you include the value of your time, most projects will be more expensive then commercial options. I do projects to learn, play, experiment, and come up with something that I can say is uniquely "mine." I also take great satisfaction in completing a project especially if it's something I'll enjoy using myself.
Hi, thanks for the video. Would love to try it. I did not see the STL files for the main mirror shroud or the dovetail mount for the red dot finder in the google drive link in the project. Can you please help me find them or add them?
I guess I didn't generate STLs for everything but the complete model is in STEP form. But I just saved out some STLs for you. They should show up now. Let me know if you need anything else. Also, check out the Hadley Discord server. It's quite active and you should be able to get quick help there - discord.gg/ycaa8nX7sa
Hi Dave, I'm building my first telescope, Maby I'm missing something but I'm not finding the mount for the secondary mirror? Is the one in the original parts?
it's in the STEP file I generated, if you're looking at my version of this telescope. But, yes, thee secondary holder has not changed from the original.

Thanks Colin. Changing the size of the tubes is pretty straightforward if you know your way around CAD design, but might be tricky if you dont.
If you can get 1/2 inch tubes then I would recommend building the stock Hadley.

Hey I was trying to see the file but I can't open the website
Sorry, I haven't had a chance to fix it.
Search designbydave on printables. All the same info on there.
Beautiful!
Thank you! Cheers!
This is absolutely amazing. I'm looking for some f4 glass to build a imaging Newtonian, this is PERFECT
Thanks for checking it out! Good luck with your project
That looks pretty cool.
I'm wondering... Couldn't you replace the secondary mirror with a camera, thus eliminating the need for an eyepiece?
Yes that is possible. I've seen a few examples on the Cloudy Nights forums.
Great looking telescope!
Thanks! I I'm pleased with it!

Awsome telescope, can you send the link of the mirrowset
Thanks

Hi, awsome video! Do you know how heavy the 3d printed parts are?
I don't, but not very heavy at all. The total weight of the telescope is probably under 5 lbs. I can weight it later.
@@designbydavee thanks for your response!
Im a simple man i see Carl Sagan i click like
...you subscribe? Haha. Thanks man. I'll be sure to include more of him in future videos. He is definitely an inspiration to me as well.
Next video ": Cheap diy Mount😊😊
I did design and build a DIY mount but it wasn't exactly cheap. This might be a good idea to look into!
How much does this beast weigh?
1326 grams without eyepiece and dovetail mounting bracket.
