My name is David Gilley, I've been in contact with quite a few people via PM here and thought I would share a design in OSLO for a 10 inch refactor. Some background, in the near future I will be moving to a darker location in Florida and am looking for a "rest of my life telescope" and for various reasons a large refractor is of more interest to me than a large dobsonian.
A few months ago I downloaded the free version of OSLO, quite a learning curve. I still have much to learn, but wanted to thank everyone who responded for their assistance and passing along their knowledge, I do appreciate it.
I may end up just purchasing an already fabricated lens, I've been advised that these particular glasses are difficult to work with and acquiring blanks of the necessary quality in this size may be cost prohibitive, but thought I would post this design, even though it may not see the light of day (or night).
