Quote:It's a Royal Astro LN-3E. You can find it in this catalog:http://geogdata.csun.edu/~voltaire/classics/royal/Royal-Astro-Optical-Catalog...Without the ability to rotate the tube, the focuser can be in some pretty awkward positions. In any case, it's a rare scope. If you ever want to part with it, let me know. I have its bigger brother, the LN-4E. The tube cap and focuser are identical to yours. It's a very nice 4" f/10.

What some may view as an argument I view as a different perspective.
Quote:Well Jimbo speaking of the "108" here is the Tasco brand of the Optica b/c 108mm x 1600mm next to a Selsi 80mm. This is a slightly newer model than the one on page 3. It has an improved clam shell, motor housing, slightly thicker CW's and different positions on the sliding tube weight bracket's locations. Mike
