    You are going to have a lot of fun with that scope! Ed

    Upgrading Grandpa's 1950 Newtonian

    I've been away for awhile. How's the project going? ed

    May have some astro uses

    I'd prefer a mouldable glue that turns into money.

    Just an old geezer

    Well THANK YOU so much for the warm welcome. I'm always enthusiastic about answering questions; I've even had two telescope makers complete their telescopes this way! My favorite student won First Prize in the optical judging at Stellafane last year. ed

    Telescope Makers (1960 film)

    I cannot praise this film enough; I don't have the words! I started later than the era presented but not much had changed by the time 1957 rolled around and I was 12. There was a comment about one man making his 14" Newt in 1942. Maybe we all don't remember, but there was a War going on, and supplies of things that were needed to grind and polish were very tight or toally restricted. On my side of the Pond, amateurs resorted to using sand for their abrasives! I can imagine just about everything needed to make a telescope was completely unavailable in Britain. Few would know that even as a victor in WWII, Britain had rationing until 1954! Yes, there is a message here and noted by another poster; times were better in the days when things were done right! And there was pride in workmanship. ed

    Improvised Eyepiece

    I really like this idea. It is not generally known that amateur DIY astronomers can make their own eyepieces from scratch, as illustrated here. All one needs to do is stick with a simple type, like a Ramsden. One needs to get the appropriate tubing first, measure the inside diameter and then search out plano convex lenses that will fit in the tube. I've built quite a few 40mm ramsdens and I've kept a few for my own use. While such an eyepiece isn't a Nagler, there is a special feeling one gets when looking through an eyepiece of one's own construction. Great job here!! ed

    Help a neighbor become an amateur astronomer!

    I've recently appended two more articles on the DIY page. Happy reading!

    World's simplest telescope

    I'll have to remember that cannonball trick the next time I have to grind a lens to that specific focal length! Actually, a lens thus ground would turn out to be excellent.

    diy telescope tripod?

    Aluminium crutches would work. But because some force has to applied to them at their points of attachment to the tripod head, I would advise inserting wooden dowels at the tops of the crutches where this pressure is applied to tighten the legs. About two inches would do. As for new bolts, my experience has been that these were quite strong enough for the job.

    diy telescope tripod?

    I'll jump in here and offer something completely different! After all, I did promise a few new articles after the enthusiastic response from my first about my neighbor becoming an amateur astronomer. It happens that I have a short article in my kit bag. Article and pictures attached. ed TRIPOD.DOC

    World's simplest telescope

    Thank you for reworking my work for me without attribution. "Artical" is spelled "article". I did refer to my probable resolution of Albeireo as an area that Galileo didn't pursue, seeing that he had other far more important things to do such as supporting Copernicus. I smell pedantry here. Is this what you do to accumulate so many postings to your credit, or do you do something more useful? At least I tried to point out an interesting and exciting project for the DIY astronomer. Do likewise; in fact, do better. ed

    World's simplest telescope

    I know this isn't a fancy article but it is a lot of fun! I show US sources for the supplies, (not much!), but I am sure that there are many similar ones across "The Pond". See the attached ed GALILEO.TXT

    Help a neighbor become an amateur astronomer!

    I agree with you. Your mom is special. I would have become nothing if it weren't for what my mom did for me. And my mom would point the finger to my ninety-four old grandmother and say that she was the toughest one of them all!
