Great project!

 

Have you checked out the internet archives for sci.astro.amateur?

 

There were many discussions about Astroscans, including where they were made and even about serial numbers, markings, etc.  I’ll bet you could find more examples and entries for your table there!

 

Looks like all the “Made in Japan” ones had long serial numbers.

 

It's an incredible scope.  The ball motions are intuitive and the rich field views, with ease of motion, amazing.  The 28mm RKE provides a floating in space vista as no field stop was visible.

 

Just wish someone would make one that's lighter, has a focuser with a set screw to hold eyepieces in place, and is collimatible.  And, adding a nice 6” f/4.5 would be just grand — like a mini Portaball!

...and, I speculate that when manufacturing was moved to Japan it must have been in 1985 which is why the serial numbers are prefixed with “85”

Hello,

 

my Astroscan has serial number #2986. I have still the original invoice from the previous owner. It was purchased at edmund scientific co. on december 14th. 1976 for 129.95 USD. Due to delivery problems with the 28mm RKE eyepieces, this scope was delivered with an 18mm RKE eyepiece instead.

 

This eyepiece had a lot of fungus after this years. I have replaced it with a 30mm Celestron Ultima which gives me wonderful views.

I love it, a Celestron Ultima 30mm for an Astroscan.
I think the 18mm RKE would be far better than the standard 28mm.
The 28 produced a bit much secondary shadow. I thought the ...what was it...21.5mm? had the best standard use for day and night.
Under 3000 is a pretty low number. I'll do the old style 30mm Ultima in my Japan version while I have them out from a recent purchase.
Might as well toss a few in the can while at it.

@apfever: You are right. The 18mm eyepiece works ok too. For the 35mm ultima i had to shorten the focuser tube to come to focus.

Just adding mine, white sticker, serial number 14231 purchased autumn of 1979. No identification as to where it was made but assuming the US. I still have the original manuals that came with it.

Hmm, I have a black focuser tube, big sticker on the outside that says Made in USA, molded Made in USA by bolt holes, but no sticker inside with a SN. Wonder if this can be rough dated? The secondary "cap" is all black molded letters and the Astroscan is painted red. It came with a full set of RKE eps.

The best we can do (using the updated data below) is get a range of dates, using the black focuser tube -- Probably the 1990s.  Let's keep adding more information (especially dates) so we can answer questions like that:

I've added quite a few additional Astroscan 2001 Serial Numbers, based on recent auctions.  I ask the sellers about the details of their specific Astroscan 2001 being sold.  As always, one can download the complete list from OneDrive --  https://1drv.ms/x/s!...bqxZ77p6XWXdU

I just pulled my Astroscan out of a closet where it's been hiding for at least 15 years, hoping my grandsons would enjoy using it.

 

It has a white sticker, serial number 6456, not USA marked.  The original Edmund manual has a 2/77 copywrite date, but I can't remember when I bought it or what the cost was.

 

Unfortunately the parabolic mirror looks badly flaked, like it had been exposed to moisture, even though stored in a dry location.

Is there anyplace I could send it to be repaired? 

 

The rest seems to be in good shape, no bumps or bruises to the plastic body, front glass unscarred.

A little late to the game, but finally (41 years later) landed one. Serial #23049, blue dot, black focuser, included the 15mm RKE EP. One focuser knob missing, and what look like a couple of condensation spots on the primary (just going to leave that alone, as the rest of the mirror looks great). 

Also, came with a loose little sticker, "ASTROSCAN 2001" with Edmund's logo and patent number. Any idea where this went?

@ The Vagabond:  I've added your Astroscan's Serial Number to the registry.  The loose sticker may go in the center of the Secondary Mirror's mounting plate at the center of the clear window, at the front-center of the telescope.  Is there some wording there already in the center of the window?  See picture below.

 

Be advised that you may be able to get the missing knob for your Astroscan 2001 from Cloudy Nights member "DAVIDG".  If you send him a Private Message (PM), he may be able to sell you one for a reasonable price (like he did for me).  He last logged in yesterday.

My Astroscan was shipped to me sometime in June of 1977.  I purchased it through a local dealer, S&S Optica, and Kathy had it shipped to my address from Edmund.

 

Its serial number is 5751 on a white sticker.  It has no markings saying where it was made.  I also have no holes on the ends of my front lens retainer clips. The inside of the focusing tube is black and chrome on the outside.  Mine came with the carry strap, the keyhole finder, and the tripod mount.

 

My eyepieces are both all black.  The only marking on the lower power eyepiece is 1 1/8" FL.  The other one is marked as Edmund Scientific Co. and RKE 15mm. 

 

My Astroscan still gives good viewing through it.  My favorites for this scope have been The sun, moon, globular, and open clusters.  It has always been my grab and go telescope.

Joe

I bought my Astroscan at a Boy Scout town yard sale.

 

The serial number label is white rectangle with machine block lettering, 49332.

It has Made in USA molded in the tube near one of the carry strap mounting holes.

It has a black focuser tube.

It has Astroscan in red on the secondary holder.

It has a 28 mm RKE with rubber eyecup.Eyecup may have been an option.

It has a "Proudly made in the USA"  Edmund Scientific sticker on the side.

It came with Richard Berry's "Using Your Astrscan". Fourth Printing 1986.

It came with Terrance Dickinson and Sam Brown's "The Edmund SKY GUIDE". Eleventh Printing February 1996.

It has the 2007 Image Erector.  Inforamtion & instructions sheet is marked 3/97. Presume this is the print date.

If the documentation is original to the scope, it suggests the scope was from mid-1997 or later.

I have one that is marked 10155 with a green sticker, purchased at an antique store in Missouri has no other stickers or markings on it on the outside, they seem to be all removed from it... Any thoughts on year of manufacture or origin?

Although the sides of the red telescope body is unmarked by the bolt holes, it's Made in USA and dates from the 1977-1978 timeframe.  I'm interpolating the data from the Registry two posts above in this topic.

I've found this "Antares astroscan" on a marketplace  here in Italy. I think it's an original Astroscan.
