3110's finder was delaminating and ugly, so I gave it 3041's right after taking this pic.

3041 has a really loud buzzing motor drive, which other than the replaced finder, color forks and damage is its biggest distinguishing feature.

I had 2 Mizar EQs, but no Mizar scopes.  Thanks to ZEN, I have 2 Mizar scopes headed to The Swamp.

 

BN-80 F5 Nature Scope:

GT-80S F7 Astro:

The GT popped-up right before I headed out last night, and I jumped on it.  Should be interesting comparing this 80mm F7 with my excellent Yamamoto 60mm F7.

 

I'm almost 100% sure that the tube rings that came with my Mizar SP are for one of 80mm refractor models.

I answered an ad for a 76mm Tasco parts telescope. No pics or price.

The seller was quick to respond and I was informed it had the wood case and the front glass was not damaged.

I picked it up on my way home from work. I had only taken a quick peek inside the case while at the seller's residence. 

    When I got home and unpacked the first layer, I got really excited when I spotted a blue box. 

I double checked the reg. number on the wooden case and the last number was not a zero but a C.

Turns out it wasn't a 10te, but a 15te!

It's missing the sun projection parts and a finder, but other than a stiff mount, the lens, tube, case and legs are in very good shape.

Note to Self:  Register 770655...

 

The Atlas 60mm AZ was delivered yesterday while I was at work (my company started an onsite rotation plan - couple days a week is work-from-home, couple days at-the-office), so I haven't unpacked it yet.  May do that tonight.

 

Fast shipping by GW; and, I didn't hear any jingles, jangles, smacks, or clunks when moving the huge box...  I'll take that as a sign of good packing - but, fingers crossed!

 

SCRATCH ALL THAT.  The big box is the new TS case for my FC-100...  That was quick!  From Germany to The Swamp.

I picked this up-it's much smaller than a 50mm vixen! I think I'll mount it with telephoto lens ring. I kept thinking about this and threekor 240, but settled down with 260 because of the focuser. The huge metal clamshell bothers me-so heavy!

 

I'm glad this thing is solidly built though-all metal. Just look at the focuser.

 

Threekor 260

 

And this thing is tiny

The focuser was bit stiff, but few screw turns and it works fine now.

more photos.  very dirty.   it is all there but the eq mount looks like it was left outside at one point.  the ra adjustment is seized.   so i mounted the scope on a spare tasco 7te-5 mount i have since it is a close match.  the tripod legs are from the jason.  the tripod metal pieces match my eikow polarascope.  

 

box itself got damaged internally but the parts are all there and all seem ok

the vixen 1.25 visual back fits so i will order another.  

 

this scope is actually quite dirty inside the ota.  not entirely sure how to clean inside without disturbing or damaging the baffles.

Orthos

 

I recently picked up a polarex 25mm ortho. The guy who gave me wasn't an astronomy guy per se..I found the tube a bit smaller. Anyone knows whether this is a telescope or microscope eyepiece?

 

I picked up the 40mm goto because I thought it was new, but turns out it's just another 40mm , the T3AH40 eyepiece.

https://www.cloudyni...-image-erector/

 

lucky it was sold with field lens. It's rather an oddball, but it's indeed really sharp.

 

The 4mm nishimura is rather self explanatory. I wouldn't pass a nishimura.

The Polarex barrel appears... "off."  It may be the angle of the photo, but its finish appears dull.  Original Nihon Seiko barrels should be shiny/chrome.  Perhaps the original barrel was replaced or reduced. It may have been modified for use in a microscope, but I don't think it started life as a microscope ocular.  Microscope eyepieces  are not normally labeled with focal lengths.  They are labeled with effective magnification values (either photographic or visual).

 

Can you estimate the barrel's diameter (relative to the other two)?  If it's 23mm, my guess is that the barrel was was either replaced or modified for use in a microscope.

 

Best wishes.

Dan

Well folks, I'm afraid Zenmarket got me again... another fine acquisition is on its way. I couldn't resist, was looking for one of these and BOOM, there it was! This one is really neat, IMO. Details to follow upon delivery... stay tuned! grin.gif

Dan,

 

The barrel is indeed smaller, like 1mm off.

Here's a comparison with shiny Asahi 20mm ep (left)

There's a brass (I think) sleeve inside the bottom half.

The barell comes as two pieces as well

Never had a polarex so I don't know if it's normal or not..

That is very interesting.  I think it's original and "stock" - but with (apparently) a slightly "undersized" barrel.  Very cool find!

 

I've seen only two... TWO... photos of Polarex 25mm Ortho eyepieces in 0.965 format (24.5mm).  One is yours.  The other was Xavier's (post #24 in the link below):

https://www.cloudyni...-unihex-barlow/

 

They are rare, indeed.

 

Xavier's looks a bit newer and does not appear to utilize a two-piece barrel.  Note the "OR" abbreviation, as well (instead of "ORTHO").  His eyelens is slightly larger, too.

 

Perhaps the brass "sleeve" includes the field stop on its "top."

 

Best wishes.

Dan

Since the barrel doesn't screw through to the top, I've been wondering about if the sleeve has been modded. I find it a bit odd that the lens is a bit "sunken". It's quite a gap from the top.

However it works well. I put some painter's tape around and it fits snugly to older prisms. Since it's long it just falls straight through to the mirror if I don't.

 

There's some pincushion distortion, but overall it's sharp on axis.

 

I didn't know that it's rare.  I was eyeing it after I saw polarex mark on it. The guy gave it to me for free, along with some other eyepiece...that has some mold in it!

At least this one is a keeper.

I got lucky and was the first to respond to the Facebook Marketplace add for this Unitron 114.  A little drive up the interstate to Phoenix, and $100 later, I have my second 114.  The only piece missing is the diagonal.  The guy I bought it from said that it was his grandfather’s, but no one in the family was interested in it.

waytogo.gif Quite a score! I'd say it's a '55 or '56. 

 

Mine is a slightly younger cousin. 62mm from about '57-'58.

Congratulations! It looks very much like my #114 that I got from the estate of the original owner who attributed it to being from 1955-56. Mine is an excellent specimen with wonderful optics, yours should be as well.

Funny how the storm clouds built up on the return trip to Tucson yesterday!  lol.gif  No rain though.  Monsoon season started today, so maybe this purchase will bring some much needed precipitation.

A few of the recent finds:
 
Example: ¥10,700 (Scope & Mount) + ¥2,070 (in country Shpg) + ¥20,615 (UPS) + ¥1800 (Reinf, photos, Zen fee) =  ¥35185 = $318.66. Not a SGW $300 deal, but you get so much more, it will arrive intact and have no surprises, even at 19.190kgs in a 71cm x 41cm x 47cm box. Yay!
 
 
Yes, there is some rust. It will be addressed - rusty lamps of this genre usually sell poorly.
Time to make more adapters...

Wow! Congratulations on your Vixen treasures! I simply adore my 90mm and, unlike many here, also love my Vixen alt-az mount. Hope you enjoy them as much as I have.
