Dan

Have you got any background to the Purple One - the mount looks quite unusual?

I made this 10" F8 Newtonian from an Edmund mirror grinding kit and University Optics components forty years ago when it became clear I'd never own a ready-made Cave scope, so it doesn’t really count as a classic telescope. But it is a reflector sure enough. It's been on a wide variety of mounts over the years but I like this Dobsonian mount I made best. It has a felt lined eyepiece box with a lid to keep the dew off on the side, and setting circles, which I use a goto-ETX80 to reference coordinates with for finding faint stuff.

This is the second Sonotube the optics have been in, They are / were made here in South Carolina so it's the genuine thick stuff not the thin Lowes ersatz

This would have been a much better photo if I'd have taken the time to clear out the cobwebs. I cap the tube but Its been awhile as I was fixing up a Cave I bought.

Even with a Flash the baffles have suppressed the light scatter before it reaches the mirror. Mathematically speaking, I could have used far fewer baffles but I must have gotten into the glue again. Though it's not so impressive looking it has excellent optics and Jupiter and it's moons looked awesome in it the other night.

Detail of the Eyepiece box, Dirty! All the pine tree pollen clings so badly.

No info at all except Frank said it was commercially made.

Here's a few:



The Bausch and Lomb RV-5+ and the Criterion RV-6



The RV-5+ was manufactured by Mizar, at least it sits on a Mizar mount. Below is a C 4.5 along with something even rarer than a Newtonian in the CN Classics forum, rain in San Diego..

Parts of it remind me of the Lomo Astele 8", but I think that was a Mak?

Its probably f12 or f12.5 (72" or 75) and I can adjust the tube length of my Superplanetary in the "A" area.
The f13 ALLEN mirror was a ebay purchase and this f12 ESCO mirror came as a extra with my Springfield 6"f8.4

The mirrors for the Springfield. It has three, primary, a diagonal to bring the light out the side of the tube, and a third to turn the light to the eyepiece because the eyepiece is stationary while the telescope moves.

Where I am you already are!


It looks somewhat inadequate given some of the other newts posted but I think my 11TE-5 counts! And hey... the Intes Micro M606 is a 3rd hand scope and such an ODD optical setup that it has to kinda-sorta have some potential-classic points....


(Sorry about the refractor that snuck in.... they always seem to want to be the center of attention!)




The scopes are nice but I'm drooling over that view! Just beautiful. I think that's where I want to be buried.

Bingo Tim! Thanks. Did a Google on Lomo Astele and found an Astromart ad with a similar ball mount. Guess they had some old Sputnik bits left over!
