How heavy are the weights? Looks like it's in good shape! Congrats!

I'm a little confused on the weights. If when I find the packing slip I'll know and then post right away.  I don't want to take one off with the scope on the tube.

Astro-Mount. Now most imports to the USA  had the "Royal Astro" Stamp from 1950s-1960s: Sears, Tasco etc.

I see that your turnbuckle is in the upper mounting holes mine are in the bottom. Somewhere I read that the best stability depended on your latitude for some reason or other. Also Mark did you check inside your motor box for any date?

Here are a few close ups to see things a little better. My green felt is intact everywhere it was needed. Obviously the saddle had it where it's needed. But then I had to take a Dremel and grind the saddle corners down because those sharp SOB's nearly gouged my tube but were caught in the nick of time. The sliding tube weights also have green felt. You have to look closely but the guiidescope's protective plastic rings are just visible under the collimating screws.....a nice touch most guidscopes don't provide.3507564-Tasco%2020TE%20Restoration%202009%20035%20(Medium).jpg Side shot 6x30 and 25x50 Finders.jpg

Focuser close up

Does your RA tangent slo-mo have flattened shafts on both ends? My mount has a terrible flaw - only one end has a shaft, so the RA slo-mo cable is hard to use when the telescope is pointed east. I just put a knob there and have to reach way up.

 

BTW never attach the RA slo-mo to the other end of the clock drive worm shaft! You can break the bracket holding the clock drive that way. THAT worm SHOULD have only one end, for the spur gear. Very strange and I sure wish I could find a 2-ended slo-mo worm.

drl I don't understand your question. Do you mean when using both slo-mo cables one sticks out the objective side and the other towards the focuser?confused1.gif If this is the case then the tube assembly is in the saddle backwards....at least that's how mine behaves.

This 20TE mount and the 6345 mount are the same design. There is a fixed worm for the clock drive and a tangent drive for RA slo-mo. The latter should have flat shaft on both ends for attaching the slo-mo cable, while the former should only have a shaft for the clock drive spur gear. On my mount it is backward - the tangent has a single flat shaft so there is only one place to put the RA slo-mo cable, and this makes it very hard to use when the scope is in the east half of the sky. The drive worm has a completely pointless and very dangerous flat shaft opposite the spur gear. If you attach the slo-mo there while the drive is engaged, you put tremendous strain on the clock drive bracket if you try to turn it. Mine was already cracked from this and required JBWeld repair. It is just a glaring flaw and the worst oversight I've ever seen in a Japanese mount.

I hate to be pedantic but Royal is a brand - like Tasco. The company who made these scopes was called Astro Optical Industries. My apologies for being this way :)

Yes a beautiful scope I was never fortunate to even look at one never minde look thru one , I suppose in the 60' if you had one you were the person , I only had the 7TE, and 10TE both good even now , but as I am not a collector sold them , as a small SCT 5 inch was better 

Out of interest as its a big scope what type of mount did it have and if one was to mount it on a modern mount  what will you use ? EQ5 minimum I think  as its so long

Yes, I know - I have purchased the 108mm in New Zealand. Identical optical specification to the TASCO 20 - TE (Royal R-102) apparently the objective manufacturer the same as the 20 - TE. Yes a Sport Master

Thanks - got it.

 

I wonder... maybe AO stamped their mark on some unusual part -- on my Sears 6336, it was on a small plate within the DEC Axis slow-motion gearing.

 

Why there?  I have no idea, as the mark was already stamped on the Label.

Yes - the aluminum blocks on a couple of my mounts (all?) have a tiny AO stamp - in a place you only see when it's disassembled.
