Hello,
I'm new here. My grandpa was given this telescope by a neighbor who didn't want it anymore. Seems to have a lot of bells and whistles, but I can't find any markings on it. Any help identifying it, information about the quality of the telescope and the lenses, and suggestions on cleaning would be greatly appreciated (it's been sitting in his basement for a while). I'm hoping to gift it to my boyfriend for Christmas, so while I'm not planning on selling it, it would also be nice to know a general value.

Without images I'm going to have to use my psychic powers on this one:

 

"I divine its an old Tasco, 60mm achro refractor, or 3" newtonian on alt az mount"

"Value $50-"

Make sure you add a pic of the name plate usually on the focuser !

Looks like a Sears re-brand of a Towa (Japan) Model 305 -- 60mm F15 refractor on the EQ-2 mount.

That is what it is.  I have the same one, but with a little different finder.  Other than that, it is identical to mine.  Mine is early 70's vintage.  It is a fun scope with which to begin this hobby.

Here are some closer pictures of the mechanism. it has 2 different numbered dials and 2 long fine tuning pieces. The only sticker we've found anywhere on it is just a little on that says "passed" on it

Yep, it's a Sears 60mm f/15. But it looks like someone stuck the barlow in the at the eyepiece end of the finder. lol.gif

From the looks of it's length, it appears to be a Penncrest (JC Penny). Depending on the year they were labeled either way. They were made by the same Japanese maker (Towa), as some Sears branded scopes but they have a 1000mm f/ instead of a 900mm. Some of them perform very well. Mine had the objective's crown lens mistakening flipped when I bought it. It needs more testing and the mount needs regreasing and adjusting but so far it seems to perform well.

Do you have the storage box?

Does yours have any residue from where a label is usually located? 

There's also a chance it could have been the same scope and branded by another company.

 

When I get a chance I'll measure mine so you can confirm that it's the same model.

If your's is shorter, it would likely be a Sears.

Thank you so much! I'll measure this one as well.

Yes there is some residue from a sticker near one of the eyepieces.

No, he sadly did not give it to us with a box. Is that something I could find?

To both of you, how did you go about cleaning and fine tuning yours? The metal pieces on mine seem to be quite dirty and the plastic material covering the two long adjusting pieces are in bad shape as you can see in my most recent pictures. Would I be better off to remove this coating? 

I'm just hesitant to start taking thing apart to clean esp. if there is something I really shouldn't mess with.

Here's some approximate lengths from my Penncrest.

If yours measures a little less than 4" of either of these measurements it's likely a 60/900mm Sears.

Penncrest-Length.jpg

 

Finding an original wood box would be very difficult, and next to impossible if it's longer like a Penncrest.

Yours is likely newer since it has plastic knobs on the mount, so it may have come in a cardboard box. 

 

Mine never had plastic tube wrapped controls. If they are chrome and in good condition under it,

you might remove it and clean and polish them. 

 

I use Nevr-Dull and or Blue Magic metal polish for cleaning the chrome on my scopes.

Simple Green and or Awesome for the smooth painted tube and parts or dilluted dish soap like Dawn, sometimes followed by car wax.

Dust and brush the wrinkle black parts the best you can and then wipe with a dampen rag with cleaner. Brush of any left over lint.

Do not clean any lenses unless you know how to properly clean them. Read up on it first.

 

As far as value. It depends on what it turns out to be, it's condition and completeness.

Either way complete kits (with box) might go for $75 to $200.

IMO, an incomplete scope like yours $50-$75

The sticker on my Sears scope is in the same place as shown for the Penncrest scope, so that won't be much help - unless you find the sticker itself.  I suspect the best way to identify it would be to measure how long the tube is - the Sears scope has a FL of 900mm, but the Penncrest appears to have a FL of 1000mm.

 

How did I go about cleaning and fine-tuning my scope???   HAHAHAHA!!!!  I stuck it in its box 40 years ago and kept packing it with me whenever I moved!  I haven't really had it out and put together in decades.  Mine never had the plastic covering on the flexible adjustment knobs - they are chromed bare 'springs'.  Like Kasmos says, the plastic clamp-knobs are also different than what I've got - mine are small (tiny, actually) metal knobs - they hurt when tightening because they are so small.  Don't know if your plastic clamp-knobs are OE or if they are upgrades.

 

Again, like Kasmos says, some of these scopes are good, some not so good.  There does seem to be a following.  Many, many people started the hobby with one.

 

Caution - you should NOT use the sun filter to look at the sun (it may crack while you are looking through it and magnified sunlight could ruin your day) - use the projection screen instead, without any filter.  There is no danger with using the moon filter while viewing the moon.  Also, remove any batteries that may be inside the accessory tray light - leaking batteries will wreck it.

Congratulations! I used to own the Sears 900mm version of this scope and it was excellent for its class.

Just measured this morning, it is the Penncrest 1000mm version! Thank you all for your help. If I come across anything else concerning or interesting as I embark on getting it back in shape I'll be sure to share. Now that I know what it is, I've also found a few good discussions on here about it. Thank you again!

That's very cool. It's much rarer than the 900mm Sears, so IMO it's the one to have. Besides the ones on Cloudy Nights, and the ones I've seen come up for sale in the last few years, I've probably seen no more than 10 total. Whereas there's almost always a Sears for sale somewhere.
