No I didn't. I did spend most of the time with the Aerolite optical tube mounted on it which

is very light and I almost always used the flex control rods when observing.

I really liked the aluminum legs with their twist locks, and extremely light and portable.

Yeah, the legs and the whole kit is super light (Hence Aero-lite?) and very attractive.

At first I wasn't sure about them, but I actually like the way they looked when I set it up and how the twist locks work.

But it seemed that the tripod would twist and flex with everything tight.

I'll have to give it another try.

 

Do you still have the white replacement?

Not the best photo, but I found this one (taken at night), of the Mayflower 806 cutdown (60/400mm) riding on the Unitron 114 mount.

May806-114.jpg

Unitron 114s have a larger diameter tube than most other 60mms so a cardboard collar was used to fill the gap.

I need to make a permanent well made collar/adaptor so any of my 60s will fit and look better.

 

If the OPs goal is a small grab go Classic mount, it's probably the best option.

Reading through all these replies, my summary reaction is "should have quit while we were ahead"(!) ... the original Vixen Polaris EQ makes the best alt-az (better than SP or GP) since in the alt-az mode suggested in post #2 and pictured in post #3, the R.A. (here azimuth) axis is centered over the tripod hub (which is not the case with the SP or GP).  A counterweight shaft and weight could even be added to put the center-of-mass over the tripod hub also.

 

Since the OP described the 60mm as a "project scope", perhaps a made-in-Japan classic mount is not essential, in which case the TeleVue Telepod (on a re-purposed photo tripod) or Panoramic (with dedicated tripod) might also be considered a capable contender ?  Beauty in Simplicity --- no slo-motion controls, but buttery smooth brass bushings with knobs making it easy to dial-in just the right amount of friction ... although paying *extra* attention to how the scope+cradle are balanced [not only along the telescope's optical axis, but also above vs. below the mount's elevation axis] will reward you with dividends out under the stars.

 

More suggestions offered and pictured here (see especially post #16):

Yes I still have the white replacement, it has wood legs.

Any 60mm can benefit from a Unitron alt-az mount!

What I like about the Unitron 60mm alt-az is you can use different size tube rings.

Here's mine with a lightweight 3 inch a Edmund f/15.

Yup! wink.png

 

I think everyone does have to keep in mind that the OP is talking about a modified Tasco 60mm zoom so I'm not sure how much the OP is willing to spend on a mount for it? Even the 114 mount (which I also recommend) usually goes for $100-$150 without legs and that's probably 3 to 5 times what those zooms go for.

That said, they are useful for other scopes you might have or someday aquire.

Here is a little alt-az mount that is interesting. The Borg AZM-100. I picked one up a few years ago and I can't seem to let it go.  Similar to the good mounts like the Unitron with dual tangent arms except it has electric slow-motion under the cover on both axis's. Dual speed hand-control with a small battery pack, comes in black or something like the old Vixen light green. Does not take up a lot of room in a backpack. Also comes in 2 version as the green one comes with a tripod (AZM-200) and the black is designed to use a photo-tripod (AZM-100). I have the black one.

Here is a link to the 3 page pdf manual on it, https://www.sciencec...ltaz/mmount.pdf

mmount3.jpg

 It will carry up to an 80mm triplet or Fluorite doublet as I have used an FL-80S, a TMB 80 SS, and an AT80LE on it. It fits on any decent 3/8-16 thread photo tripod although I use a heavier Bogen 3021 or 3221W because that is what I have.

The following are examples of some very nice mounts, IMO.    They can be found on a variety of scopes, and had a few variations.

 

Mostly they were used on 60mm telescopes like the 7TE series, Space Scope, and many others.  They also came with an ATCO 1254 (80mmx 1200mm), but I think that long tube may have been too much for it.  But the mount seems find on a Selsi 247 (80mmx910mm).

These mounts have smooth dec and RA controls, and when equipped with a CD, they track pretty good too.

Those scopes use objectives at f/7 or so (60/400mm) - the long tube is a consequence of the image-erecting lens train. I converted 3 such scopes to super-finders/side scopes with excellent results. You have to saw into the tube and install a new focuser in the sawed-off part.

-drl


I acquired this setup with the conversion started. The original tube and EP/erector/zoom are intact and a second sawed off tube is fitted with a plumbing parts focuser. I do have a focuser and diagonal to finish the conversion but still use the makeshift focuser.

Is there anything useful or interesting to be done with the internal components of these units? Make an EP and barlow? Educational props? Demonstrate fracturing glass? Does everyone just squirrel them away for "completeness of kit" should they ever put it up for sale?


Why are these zooms generally poor optically? Are the internal lenses not made by the same folks as the vaunted Japanese objectives?

That Cave is going to be perfect for a 'more portable' 60mm setup primarily targeting AltAz or EQ if it doesn't add too much weight. waytogo.gif


Certainly not the first time two astronomers had different definitions of a "grab and go" setup! It is a wonder the IAU hasn't weighed in on the subject...yet!

 Has lots of slop and play above the DEC lock.

Did you check the coupling(s)?  Some of these had a cradle attached, and the bolts below that can get loose...

Of course the tube clamp would have to be larger on a 80mm, but is the mount itself the same size as on the 7TE and the ATCO 1254?

Yes, the 7TE and 1254 mounts are almost the same.  Some of these mounts have a different orientation for the dec cable.

 

Here is a Selsi 247 mount:

 

247 mount.jpg

 

Even though this mount looks the same at the others, it is wider.  This mount for the Selsi is 1-7/8" wide, and the others are 1-1/2" wide.

This EQ resembles the earliest TAK EQs, too...

 

(Wider across the polar axis at the latitude hub; and, with that polished metal end cap,)

Tak and Tinsley make good mates. With so many much younger mounts in the neighborhood Tinsley was a bit concerned but Tak assured him he was ageless in her heart, and eye. Love conquers all

It's a Goto #453 3" X 1300 mm. It took me like all morning to figure this out as the mount photographed darker than the battle ship grey that it actually is.

Goto, that figures as it's mount looks very substantial. Probably cast iron and heavy.

 

If you ever get a chance, I'm sure everyone would like to see photos of it.
