I'm almost done with my 13.1" scope with a stationary altitude for the
eyepiece. I just can't seem to take the last 6 hours to finish it. I've
promised to post my experience and lessons learned as well as photos.

I believe the scope in questions is for an 8-10" mirror. That might still
work. My 13" f4.4 OTA is 54" long so the eyepiece on top of the pier is also
about 60" off the ground. Tough for someone with limited access. Preliminary
trials look very good.

My particular design also features a built-in sky atlas desk and the entire
scope still fits exactly into the back of a Honda Accord.

Thanks to a team effort, the book:
William Frederick Archdall Ellison.
The Amateur's Telescope.
Belfast: Carswell, 1932.
107pp.

has been posted to:

http://www.gfphoto.com/atm/book/

The files are two .pdf files, 2.5 and 2.2 megs.
The printing in the books these were made from is poor quality, and so these
.pdf's do not look great. There is also a photo of what is supposed to be
Ellison's first telescope.
