Is your problem insufficient in-focus or out-focus? If out-focus, is there a drawtube? It will be secured by a thumbscrew just behind the focuser. The knobs control fine focus, the drawtube is for rough focus.

...unless as previously mentioned, yours is the more scarce non-drawtube type. If it is, the focuser should have very long travel. And if that's the case and it's still not coming into focus, I'm stumped.

It sure was bright but I had trouble getting it to focus.




All the more reason I think you may have the telescope as in the photo I posted. See if you can pull and/or twist the black focuser drawtube out like you see in my pic. It may be stuck in there from not being used for a while.

Very nice first Classic - congrats. You'll enjoy that one.

Hey guys, doesn't that one look like it may have the tube extension fully retracted? If so, you my friend, have even a rarer classic.




Hello Albert, as I was going thru my data base of 75 or so Tasco 10/15TE scopes, that was the first thought that came thru to my mind as well. I do not see the thumb screw to tighten the slide out inner draw tube. Therefore I bet it must be the very early late 50's or very early 60-61. The 1962 Tasco catalog shows the 10TE with the later inner chrome sliding draw tube that everyone is familiar with. In fact the 62 catalog is still showing the larger more square wood box that your scope used. The catalog picture may have been from 61 or earlier for all I know in the 62 catalog.

So I'm betting that wdretired has the same box or "wooden crate" as he calls it.

Of interest with respect to serial numbers are that I will now have three (assuming wdretired's scope is the older pull out extension style) serial numbers that are 9704XX. I've attached a picture from my undated late 1950's thru 1961 at the latest catalog which advertises the introduction of the 10TE to the United States which matches these scopes. I can only assume that these must be the earliest 10TE models that were produced by Tasco. Could that mean that these scopes are from 1959 give or take a year, that is what I have come to believe.

Note that Tasco started using serial numbers 9705XX and up for the styrofoam insert boxed scopes that are the 10/15TE-5 models which I believe to be for the years 1969 and later.

I sure appreciate your patience with a truly beginner. I will check to see if the "focuser" will move/pullout. I like the fact that I can unscrew one screw and take the whole telescope tube out without having to dismantle any of the long viewing tube. I'm also thinking I'll take some more photos because without a manual, I have no idea what any of the actual descriptions are. You guys have me really excited about this. I've never had anything "Classic" before. One more question. How can I clean the eye pieces. Are they suppose to come apart to clean? I noticed some dust on what seems like the inside of the eye piece. In the "Spare Parts", are a couple of small glass/metal rings that look like they belong to the inside of an eyepiece so I was thinking that someone was "Customizing" their own eye pieces. I'll try to take more pictures later. Thanks guys for all your help.

Before you start taking things apart, ask questions. Lots of questions. (For example, there's a thread around here, somewhere, that explains how to completely overhaul your EQ mount.)

Thank you for the information. I sure will look for that thread. Some wanted to see the box the telescope came in so I'm putting up a photo of it. What are the two blocks of wood with the felt on the edges? It's got me scratching my head.

I would like to know what the flat black metal thing is here that has a thumb screw in it. Does this belong with the telescope? The hole is almost the size of the shaft holding the balance weight.

That's for solar projection viewing, it attaches to that part in your box that looks like a lollipop & that in turn attaches to the draw tube

I agree with Albert about yours being the rarer model, & more of your focuser should slide out, where it meets the white optical tube

Solar Projection Viewing . . . I guess I have some learning to do before I get into that. I took a picture of the slide out tube I think you were talking about. I slid it all the way out and I still could not get it to focus. At this point I can't help but believe that maybe the eye pieces aren't all there. I took a photo of two little metal/glass barrels (above photo). Are they suppose to be screwed into the eye piece? I've tried screwing them in one of the eye piece (and it seems to fit) but I'm just guessing. Can you tell me what size eye piece I have? I think I'll just order a new one and start from scratch if I can find the correct size. What power (mm) should I get for viewing the moon?

Do you have a "regular" 90 degree or right angle shaped diagonal to place the eyepiece in? What you have is for giving you a correct right/left side terrestrial diagonal. I would advise low power for the moon, like a 26 or 32mm. The higher the eyepiece number, the lower the magnification.

Call me crazy, but I think they're saying the black tube, that the finder is mounted to, might slide out too. If that's true, you might get the extra distance you need to get your scope to focus better. (Take a look at the picture that was posted earlier. You'll see that the finder is further back from the main (white) tube than yours is.)

Don't break anything. I'm not 100 percent sure that I know what I'm talking about!

EDIT: I'm talking about the picture posted by Albert on the previous page. The one with the hockey goal in the background. (Notice the extended black sleeve that has been slipped out. Do you have one of those?)

This picture may help. Grab a hold of the finderscope stalk(not shown here) and gently pull to the rear to achieve rough focus. You have a classic!

Thank you for the information. I was able to get mine to pull out so I'm thinking that will cure the problem. It's raining outside or I'd be out side testing it out. Another question I have. With the smaller eye pieces these telescopes have, what is the best method of photographing what you see? Are imagers the best way to go or can you hook up digital cameras to the lens?

You are right that the RA needs to rest on the support, but the lever will still be in the wrong place. But as I mentioned, it will work where it is as long as the locking lever is working against the brass spreader. I am at work, but I think the casting is different (raised)for where the locking lever goes. The top screw which connects to the split ring has just a countersunk casting like the other screws. The lever should be closest to the counterweight shaft.




Hello Charlie and wdretired,

Here is my 10TE mount that I reversed the Polar Axis to match the orientation that wdretired is showing in his picture. In my opinion his mount is identical to all of the 10TE mounts, he just needs to rotate the RA and Dec Axis to have the Polar Axis resting correctely on the Polar Axis angled rest stop bolt.

Note: Before rotating the mount to the correct orientation, you should do so without the scope or counterweight. You need to have the Polar Axis housing of the mount resting on the rest stop bolt to help support the weight of the scope and counterweight. If not, then you are relying only on the Polar Axis Clamp Screw to hold the scope in position when you set your latitude for Polaris.

I'll post a picture next of my mount reorientated correctly to rest on the Polar Axis rest stop bolt.

Stephen

Here is photo showing my 10TE mount rotated back to the correct orientation so the Polar Axis is now resting on the rest stop bolt.

Last, here is a close up showing the Polar Axis rest stop bolt supporting the weight of the Polar Axis housing.
