It's not my normal style to create a gallery of my work, but several people have asked, so here are some images of some of the telescopes I've put together over the years.

I won't include a lot of detail on any of them, but if you have questions, please ask.

If anyone can get some ideas of things to do (or not do) from these examples, so much the better.

There are certainly others, but that should provide a pretty good sampling. (Note that I seem to cut circular holes in most of my scopes. Go figure.) :crazy:

Thanks for sharing the photos Ron.
Your work has certainly been an inspiration to me.

So how's Perth doing? I've never been on the West Coast of Oz, but have spent multiple wonderful times with fellow amateurs around Alice Springs and the Sydney area. In fact, my scope "Alice" was named for Alice Springs, and was built for my first trip down under. She sports a contrasting wood map of Oz on the mirror box cover (visible in the "ready for travel" image and possibly in the below image taken on my first trip in 1991.

And four of the six 10" f/5.6 scopes we named for places in Oz, including Uluru, Kakadu, Kaputar, and Darwin.

My current 10" f/5 is called "Wiruna," which is the name of the Astronomical Society of New South Wales observing site and is an Aboriginal word meaning "sunset."

Always glad to hear from Oz.

Very nice work.

I really like them all.

The second generation of the Alice scope, 10" F5, is very interesting.

Regards,

Tony

Tony,

You've used it, haven't you? Do we need to meet some night and put her through her paces (once the weather gets warmer, of course)?
