You have some of the most beautiful scopes.
And a wonderfully warm and inviting looking home.

That's very kind of you to say so.  Much of my time is spent working on both scopes and home.

Pardon the blurryness, twas night when I took this.  I figured I should start sharing some of my oldies.  Here's my ATCO 1282 (76mm F15) mounted on my beloved Polaris.  An absolute *pleasure* to use.

 

Once my newest project is finished and I get a clear day, I'll take a family photo with the rest of my classics.

Very nice contrast on the shot.  

 

attachicon.gifLX 2080 (2-7-2020)-3.jpg

 

This is a Meade 8” 2080 LX possibly from the second production run in 1980, the so-called B models (SN 801334). The first production run featured a 30mm finder and the thread on the rear cell was slightly different than the ‘standard’ SCT thread. The B models corrected this problem and featured a 50mm finder. Another unique feature of the early LX models was that the secondary had only 2 adjustment screws mounted at right angles to a center retaining bolt instead of the more familiar 3 equally spaced adjustment screws. The telescope is also 100% metal, event the retaining ring for the correction is anodized aluminum. The finder bracket on this example is interesting in that it is mounted on a rail the runs from the rear cell to the front and only has adjustment screws on the rear ring with the front ring being a friction fit. It’s too large for a 30mm finder and a tad too small for a modern 50mm finder. I scrounged around and found a slightly undersized 50mm straight thru finder that I could squeeze into the bracket and align. I’m currently looking for a 50mm right-angle finder to replace it with, but for now this one works fine. The most significant feature of the LX is the introduction of a worm & wheel clock drive instead of the spur gear drive of its contemporaries. This made the LX particularly well suited for imaging and the LX designation supposedly stood for Long eXposure. I took advantage of the spot of clear weather that we had list night for a first-light run with this scope and found that the optics were excellent! The collimation was very close and needed only a little tweaking. I was happy to find that the unusual alignment screws on the secondary worked fine and in some ways were actually a bit easier than the more conventional 3-screw system. The super simple ‘plug it in and it runs’ clock drive worked fine and the tracking rate was spot-on. With the addition of a right-angle finder this is going to make a fine star-hopper!

 

P.S.

 

While I was giving my ‘new’ LX a quick test the moon was so pretty that I couldn’t resist taking a quick set of images before the clouds rolled in...

I hope that, when you hacked it together, you used the SCT corrector AND secondary.  The mirror lens has a window and a doublet secondary, with the aluminum on the back of the doublet, so the light passes through the glass twice.  I have two of these now.  The first was so-so.  The second had a broken window, but it was only $20 and was otherwise pristine.  It's been sitting in my shop for a few years now, though.

 

My 2045/LX3 has spectacular SCT optics.  One of my favorites.

Yes, I did. The Mangin mirror doublet secondary is sitting in a drawer now.

It's got a perfect startest and splitting Polaris or the double-Double in Lyrae is a breeze under my terrible city skies. I have this mostly in use for sun observations with a Herschel prism. The granulation is visible in more contrast than in my Telementor. Saw Saturn last summer with the Cassini extremely well defined. It's a keeper for sure!

It’s a very interesting scope Stefan, I don’t remember seeing it before. It’s loooong! Very nice looking too!

You've got me scratching my head with your reply here Stefan - I also have an AE-72 which is a 76/1400mm,  branded "Yosco (York Optical - an Australian distributor) but it is an SYW/Yamamoto, #16254: I was under the impression that these scopes (& their optics) were the sole creation of SYW (with nothing to do with Royal Astro, hence the SYW in the diamond logo) - but of course I could be wrong..! scratchhead2.gif

 

EDIT: Doing some more research I note that someone said here back in 2013 (Mark, "gts055" - from Victoria, Oz) that he owned an SYW Yosco...interestingly I got mine from Victoria but it wasn't Mark's because of a distinctive error in my scope's I.D. info...he suggested that because both SYW & Royal Astro used a similar 76/1400mm lens that he "suspect(s) the lens sets come from a common origin.

 

I'd be interested to hear more on this matter - but I'm still mystified as to why Royal Astro would also label their scope as an "AE-72" because one would think that would be an entirely individual choice of whoever put together any particular telescope & not refer back to a common set of objective lenses...the table I post here would suggest to me that this naming is entirely an SYW decision.

Additional information: came across an archived thread where a gentleman (Chris Charen) claimed that the lenses for the 108/1600mm  were from "Horiguchi Optics"  https://www.cloudyni...00-mm-review/  

 

 

Confusingly his scope shows on the focuser I.D. "108/1600mm" & "AE-106" under the "Sport Master" identity...whereas the table I posted above says the AE-106 is a "101/1600mm scope..? confused1.gif

 

Seeing my AE-72 says it has a f/l of 1200mm which it clearly does not have from measuring the f/l, perhaps there is a lot of confusing information out there on the scopes & optics..! lol.gif

Label on my refractor says Iveco Model AE-72 D=76mm f=1400mm No.13315 SYW.

Iveco was a german optical and electronic products importer from Japan. The owner was a man by the name Israel Weissbort. The company was located in Stuttgart/Germany. Weissbort imported telescopes and binoculars made by Yamamoto (SYW). The AE-72 was the top of the line model in the Iveco offerings. Weissbort also offered a smaller model CA-60 (60/800mm) and a 30x60mm spotting scope. It is believed that Yamamoto utilized Astro Optical (Royal Astro) optics. Much like other Japanese manufacturers, Yamamoto delivered telescopes with custom labeling (Milo, Denkar, Prinz etc). The Astro Optical catalog of 1960 shows a strikingly similar looking achromatic refractor 76/1400mm R-73. It also sports a heavy duty Lafayette Arcturus style radial focus wheel that was never offered with the Iveco.

Some additional information I found: Yamamoto was a small manufacturer with a small number of employees making telescopes from around 1965 to 1985? The Yamamoto factory was in Itabashi, near Takahashi and the founder of Takahashi seisakusyo and the president of Yamamoto were relatives (CN post 1538528).

 

Info thanks to Galakuma, MASILMW and Dave Tinning.

 

I wrote bits of info down when I purchased my Iveco AE-72 from the widow of a deceased amateur astronomer in 2014. I would love to hear from others to lift the veils as to the origin of the AE-72 lens.

Looks to be a 1979/80 C5. 5X24 finder. Sadly shows little signs of use!!! Such a well made instrument. Mirror shift? Nope. Why can't they engineer this now? I can see de-forking, adding rings and using on an Alt/Az as I can't get used to fork mounts observing Circumpolar. I know, offset yourself, which loses tracking. At which point I might as well ditch the forks and go with a more portable mount. Clear and steady skies......

It also sports a heavy duty Lafayette Arcturus style radial focus wheel that was never offered with the Iveco.

So, you're saying it is an SYW - I did think it was inconceivable that any other firm (such as Royal Astro) would name their models the same as "AE-72" Stefan..! wink.gif

 

Iveco is like Yosco here in Oz (York Optical & Scientific Company) who were the importers of SYW for Australia.

 

I'm not convinced that SYW/Yamamoto used Royal Astro but I take your point about it being one of the popular opinions - the Tasco 20TE which was made by Royal Astro has a very similar appearance, reinforcing this idea!

 

Chris Charen, the New Zealand person whose thread I linked to in my last post made the comment that <"Galakuma / Hiroshi had written that the lens was made by Horiguchi optics which was the same as an early product of Takahashi seisakusyo.">

 

I guess Galakuma would be as close to the authority in these matters as one could expect, but who knows..? shrug.gif

 

Mark (gts055) the person in Melbourne (Australia) who also features in that thread has replied to a PM I sent him today but maybe we'll know more after we've exchanged an email or 2. Mark has several SYW scopes including 2 of these beauties...one is 108mm & the other is 106mm, so the idea that they are completely standardised seems to be a bit out from his information & comparing their objective diameters to the Yamamoto/SYW table I posted earlier...

 

I did say to Mark that I thought my Dai-Ichi Kogaku 80/1200mm appeared to have superior optics (on the proviso that all my comparisons so far have had an element of subjectivity in them) but notwithstanding this, my SYW AE-72 has excellent optical performance & as I said to Mark, sometimes some individual products such as my D-I Kogaku (which has a woefully inadequate mount, despite some quite innovative features) can come of the production line (or more specifically the lens production line) with optics way above the usual...

Sears switched from RAO to SYW when their 3” refractor went from the model 6339 to model 6344 in 1969. They offered the 6344 from 1969 thru 1972. They were very nice scopes. I had one (it now belongs to my daughter and grandson).

From the mid-70s, this was my younger brother's birthday present from my folks. When he went to his reward it came to me and I passed it to a neighbor, a woman in her 70s who enjoyed viewing the Moon and planets when they were available. We know how frustrating these old alt-az mount could be to use, so when I saw Vixen U.S. blowing out their 70mm alt-az package I gave one to my neighbor which she found easier to use. 

So. now this old scope comes back to my stable.
