So I picked up a Sears Discoverer today for $50.

Has a crack in one of the focuser knobs and the rubber on the feet is dry rotted. There is some tarnishing on some of the chrome and the stand shows a little wear.

Came with eye pieces Ke22mm, HM9mm and SR4mm, a Barlow, a sleeve for the AA light batteries that has replacement bulb info on it. Has some image flipper gizmo maybe for land viewing?

Everything seems to work. The best setup I've had so far. Super excited!

Tip: Use a red bulb instead of a clear bulb.  smile.gif

  That 'flipper gizmo' is the telescope's low power finder. Nice find. Good price. Enjoy. waytogo.gif

Nice find. A classic from the 70s. You can see the manual for this telescope here:

Congratulations on getting a great scope. I picked one of these up last month and it is just so much fun. My 4451 seems to be very close to yours (slo mo cables are somewhat different, but who knows - one of us might have replacement knobs). Mine is Haint Blue, though, not white. Wonder which one came first.

Great find! At the end of April I've finished restoration of exactly the same model, branded as "Olympia": https://www.cloudyni...oration-thread/

 

Be careful not to wash up the print color labels on eyepieces while cleaning them - I've found out they are not resistant to isopropanol.

Chain spreader, mount, tripod seem to point to late 60's. Did this come with a wooden case?

Good ole Haint Blue should predate white tubes?

Like it was said in post #5 probably late 70's. I don't think the ones with a flip finder ever came in a wood case.

It is correct. The plastic knobs and the type of mount point to the end of the 70's in my opinion. I think these are the last "white" models, before the era of silver refractors with silver painted wooden tripods began - which in my opinion already heralded the end of the era of Japanese domination ...

Great find and price for such a very good scope. The optics in these scopes will rival any other achro, and surpass many of them. Hope you have much fun with the scope, would have been proud to have owned that one when coming up, and even now.

It did not come with a wooden case when I got it. The only thing it came with that I didn't post a picture of is an eyepiece adapter that I believe flips the image for land viewing. I will add a pic of that on Wednesday.

Mine was in cardboard - the original box.  It was a decent performer once I aligned the flip finder.

I think that Sears went from the Tower bronze-brown telescopes in the 50s to the gray tones in the early 60s and the haint blues in the mid 60s. White tubes appeared in the very late 60s and 70s. At some point in the 60s stores were selling a mix of grays and haint blues. If you bought from the catalog where the photos were in B&W the tube color you would receive could be either of those. I guess this happened every time they transitioned to the next tube assembly color.

I saw the moon last night. Very bright and sharp.

 

The eye pieces can use some cleaning. Going to clean them and look at the moon again tonight. 

 

Couldn't ask for more for $50

 

The 3 1/2 hour drive to get it was worth it

By the way - can anyone tell what the real name of this model is? I mean the manufacturer's nomenclature, not the names given by dealers like Sears ...
