Thanks y'all.

 

I'm going to do some more digging into the "Danchyka" name.

Curiouser & curiouser!

 

In prepping the documents for scanning, I noticed that the page "The SPACE SCOPE as an Equatorial Telescope" is an insert to both manuals - it wasn't stapled in like the rest of the document.  An oversight?

 

These two will be large PDF files, so I'll have to upload them to either the Classic Telescopes or 60mm Telescope groups on Yahoo!

 

Low-res JPGs are at AC --> http://astronomyconn...model-151.2752/

 

The PDF manual is at Yahoo!

Hi JW.

I've got two space scopes.

 

One FIRST SPACE SCOPE:

With an Akron receipt dated 6/11/57   #151 Space Scope for $89.50.

Serial Number:  019409   Danchyka No. 39910

This scope came with two manuals,  both are different.:

 

One manual with the the front page photo of the scope pointed to the UPPER RIGHT (reversed from the manuals you show). 

And this manual has a counterweight rod attached to the sun screen connection to the barrel of the focuser, supposedly to counter balance the weight of the sun screen projection plate.  There is no threaded hole for this provision on the scope I have.

A  NOT FOR SALE over the Printed in Japan on the lower right back page.

 

The other manual has the front page photo of the scope pointed to the upper LEFT and the same as your manuals.

Printed in Japan is the only words on the lower right  back page (no NOT FOR SALE)

 

 

Now  the SECOND SPACE SCOPE:.

No receipt but was purchased at a pawn shop in 1978 for $50.00.

Serial Number:  051298  (yep, I read it over and over again to verify this number is correct)

No objective name.  No. 43329  60mm f+=910mm.

 

Hope this helps.

Jim

Some differences between the SS151, Mayflower 815, and Monolux 4380:

 

1. The 151 eyepiece adapter is plainer, and has three thumbscrew holes.

2. Like the 4380, the 151 has a curved back diagonal prism.  But the 151's eyepiece casting is heavier, and has a thick ring where the thumbscrew attaches.  The 151's prism is slightly wider.

3. The 151 has brass baffles rather than aluminum.  They're thinner, with more of a knife edge.

4. The 151 dewshield uses friction rather than threads to stay on, which gives it a thicker lens cell.

5. The 151's finder is centered on the focuser, rather than left of the midline.

6. The 151's finder is at least as good optically as the 4380, and both are better than the 815's.

7. The 151 has better contrast than the other two 60x910 refractors.

8. The 151's R&P chromed barrel is 115mm long ::  815's is 105mm long; and, the 151's OTA is correspondingly shorter.

9. The 151's focuser housing (cast aluminum) is cruder than the other two, and it has the raised square for the label.

 

If the weather cooperates - and I wake up on time - I'll image Jupiter with the 151 tomorrow morning.

Sorry, no imaging this morning.  The 151's views were too good, and I got too comfortable at the eyepiece.  I didn't want to disturb the tranquility on a Sunday morning (I do a lot of cussin' & fussin' to produce a dozen or so videos).

 

The 151 is a keeper.  Its views of Jupiter are as fine as any other 60mm f/15 in this class.  I watched Europa swing away from Jupiter, and twice during the session meteors streaked through the FOV.  How cool is that?

 

It occurred to me that 60 years ago, the designers of these Space Scopes came up with a near perfect kit, like the equally old Questar.  Both are portable, capable, and built to last.  Use them for a while, and you get hooked.  Use them with quality modern eyepieces, while sitting in a cushioned chair with a big blanket wrapped around your legs, a jug of coffee at hand, and your dog snoring at your feet... Imaging?  Now way!  Why make a movie when you're already watching the show?

Pretty obvious that the 151 is older.  Its casting is thicker, cruder, with a smaller prism, and the curved back is brass rather than aluminum.  It also uses field stops.

Here's the eyepiece end of the ridiculously long terrestrial viewing assembly:

 

Attached File  Space Scope 151 - P16.jpg   434.86KB   7 downloads

 

Thanks to the warning, I didn't lose the "BB"!  Got it cleaned & reassembled.  Based on the design and the manual, it must be a KE30.  I'm going to test it against my 1980s Vixen KE30.

 

Also, the finder eyepiece (R20) has both 6x (finder) and 45x (telescope) engraved on it.  They didn't waste anything - multipurpose accessories.

 

The Assembly is 10.25" long without the eyepiece... So, I gotta ask, did some other company have a patent on the porro prism design?  My Monolux had the standard barrel style.  The Mayflower has the N-K / N-S 2 bare prism (ultra-compact) style.  If aluminum was scarce...  And, at the 6" point, the cell holding the corrector lens has a 1.2" threaded piece that fits into the widening base.  Just thinking out loud about all the work & materials that went into this thing, and mine looks like it was never used.

As for the 151's maker:  Makes sense to me that AOS morphed into Astro Optical, Ltd first, then into Royal AO.  The only nit is that my 151 and a few others don't have the two small tensioner screws on the top side of the focuser casting - like my RAO Sears 6336, or my unbranded 50mm spotter.  Personally, I like having those to take the slop out of the R&P.

 

I've been over the OTA twice with a magnifier.  The only mark so far is "Japan" engraved in the pinion's unpainted aluminum cover.

Following this Space Scope link it seems like there is at least 3 versions of the Space Scope manual?
I wonder if the contents of yours are different than Bomber Bob's or mine, which I've scanned into PDF format and offered up on the freebie forum? Post #16: http://www.cloudynig...iveaway-thread/

Cold front swept away the clouds, and the air wasn't as stable as I'd like, but I observed & imaged anyway.  Here's a raw sample shot with my cheap Orion StarShoot II:

 

Attached File  SS151Moon20151120A04.jpg   11.11KB   11 downloads

 

Check out that limb - every bit as sharp as in my Hiyoshi.

 

I also evaluated the KE30 from the terrestrial assembly.  Features were crisper and the sky was blacker than the 1980s Vixen, but that eyepiece has seen a lot of use in 30 years, while the 1956 model has seen very little or none.

 

This AO(?) lens and OTA are excellent.  The Alpine Valley and Plato's wall shadows showed well up to 227x with the Meade Series 2 ORs, with the most pleasing views at 152x with the OR6.  I'm going to leave the 151 in .965" format to keep that nostalgic feel.

A couple of raw test shots tonight with the Philips SC900.  NWS promises clearer skies in the morning, so I have the 151 and gear prepositioned in the workshop.

Got some good Jupiter videos this morning.  I really respect Yankees - it was F30* when I started, and the temps dropped a couple of degrees at dawn.  No more winter morning imaging for me!  My arthritis had me creaking in the cold.

The disk is small at the SS151's native 910mm FL, but the SC900 captured the crispness pretty well.  These vintage Japanese lenses give sharp views.

This is a pic of my 40 bucker Space Scope. A bit rusty and crusty but she sure do got some nice legs and pretty eyes (excellent optics). Her legs are heavy suckers but she sure is stable.

I'm a 6 footer so this should give you an idea just how tall she is with her long legs extended. I could actually go another 6 inches or so if I absolutely had too.

It's all about the legs on this sexy beast. Whoever made these legs get's a double thumbs up from me cuz' she is rock steady and scarcely twitches when I focus her. :waytogo: :waytogo:

Assuming proto-Astro Optical made the OTAs, they got off to a great start with the 151.  The views are wonderful.

Seller had a yard sale a few weeks ago, set the 151 out there with its case open, and a $35 tag... not one person made an offer or even asked about it.

 

Inconceivable!!

 

Looking at a Japanese Calendar Converter, the "31.1.11" date corresponds to 1956, around the last week of March.  So the 151 is a bit older than my Edmund 4" with a Japanese Carton lens.

How did you come up with your date conversion?

 

See http://en.calc-site.com/search_dates

 

31.1.11 = Wednesday, January 11, 1956 - For Gregorian Date
                Japanese calendar: Showa 31
                Old calendar: November 29, 1955 Senbu

 

32.1.25 = Friday, January 25, 1957 - For Gregorian Date
                Japanese calendar: Showa 32
                Old calendar: December 25, 1956 Shakkou

 

Do you think the scope was crated and inspected for export per the first Jan 1956 date and then sat for a year before being re-inspected per the Jan 1957 second date and finally shipped to Akron?

 

Since the Akron invoice is April 22nd,1957, the scope would of had to been shipped out from Japan by sea soon after the Jan 1957 date to be in stock at Akron a month or so before the scope was ordered. Not sure how they handled inventory back then. You'd think the scope was built in Fall of 1956 as opposed to Fall of 1955 unless it got lost in inventory for a year....just thinking out loud.

 

Bomber Bob, I've been looking over other Export Standard Optical Goods tags trying to see what the earliest dated one known so far is. Just try to see when they started being used for optical goods in Japan.

 

Date range of known tags I've seen here on CN cover the dates from Jan 14th 1956 thru Dec 6th, 1957. But I haven't tried to look for all of them...maybe start a new post a see what the real known date ranges are.

 

BTW, I took another look at yours and see that are two parallel red ink lines drawn thru the 31.1.11 date. To me that just backs up in my mind that it was reinspected before it was finally crated and shipped in April 1957.
