I’m converting mine over to alt-az. I got rings and a Vixen rail for it, made a stainless steel and aluminum handle, and plan to use it with my modern Japanese Sightron alt-az mount and tall wooden tripod. It’s also been converted to 1.25” with a Vixen visual back. It will be fun to compare it with my Takahashi FC-76. I plan to use it as an outreach scope when the moon is well placed. They are an impressive length and such a classic look. It will be fun to do some outreach solar white light viewing with my Lunt Wedge while we have a lot of sunspot activity. I figure folks would get a kick out of seeing it in action.

Gorgeous! I love the wooden legs on it, the black metal legs aren't very attractive (and are wobbly to boot).

Once again my Mayflower 814, 815, and 80mm 816. I have since given away the 814 to a friend, who has basically ruined it. frown.gif   The 816 has the best optics of any telescope I’ve viewed through.

Bob, that is one Tremendous Trio!!

 

I followed-along with your restore work eagerly -- and The Proof of your Labors is in the pudding.

Thanks but those legs haven’t been on it for years. It’s back to the original metal legs. One difference is that it has a black metal Vixen triangulation tray which seems to add a little stability, (when legs and tray are locked tight with their wingnuts).

Long Live this Yamamoto!

 

Whew!  I think my SYW 60 F7 finally has a Home:

This MIZAR Yoke Mount suits it to a Tee.  Very smooth motions - a good thing as there's no Slo-Mo gearing.  Should be fine for low to medium powers.  Hoping to find that out this week.

Since y'all are Yamamoto owners, I'll "ask" this here (I may have already answered my question).

 

My first views through my new to me 815 were disappointing to say the least. First with the supplied ep's, then adapting to 1.25's, I could only achieve focus at the lowest magnifications as the draw tube was racked all the way in. I set it aside for a while to sleep on it and concluded the glass had been tampered with.

 

This evening I took out the glass, marked it as it came, then flipped it and put it back. Kapow, now it works! I still used the 1.25's, but I can run through all sizes with phenomenal results. I even ran it up to 303x on the Moon with no disappointment. Out of a 6" drawtube, it only uses about the inner third, but it doesn't seem to matter.

 

So, my "question" is, did I do the right thing? I should add the objective clearly had been taken apart sometime in the past.

Absolutely! Just make sure the spacers stayed put and check the Newton rings and collimation if you can. But if you got 300x+, you're probably on the money.

If it didn't work before, and it does now, you did the right thing.

Thanks for the reassurance. At this point I think I should just leave well enough alone.
