The current standard is 1.25" or even 2" diameter. This was the Japanese standard at the time.

Set as it is, you track more as if you are drawing diagonals on an Etch-a-Sketch. Set properly the mount will track a celestial object seamlessly. The way your scope is currently set up, the movements are either up or down (alt) or horizontal (azimuth). When pointed properly (one axis at the north star) the telescope can be guided along the other axis which will follow the same curved path that the objects in the sky take as the earth turns. The kind of mount you have is called a German equatorial mount, eq mount, GEM. She will be thrilled to know aquatic mammals are treading the waters in her home state. You have an excellent scope which came from a relative which makes it so much more precious than anything bought on eBay or craigslist.īTW my daughter lives in Bozeman. Was your grandfather-in-law from down under by any chance? I recall there were some odd numbers related to scopes marketed in Australia. There are some examples such as yours that just don't fit.

This theory works perfectly until it doesn't. In the label I've attached 7 would describe the year (1967 or 1977 IDK which) 61 would refer to the diameter of the lens at 60mm and 356 would be the scope number in sequence of production for that particular year.

Just copy the "image code" and paste it in your post, press enter, copy the next picture "image code", paste, etc. If you upload the pics you want to post to photobucket, you can embed the images into the post. And to answer your final question.this forum works just like most others. My hubby cleaned each eyepiece with rubbing alcohol but it didn't make a difference. But when I try to see Venus and Jupiter, there's "blemishes" in the view.as if there's something on the eyepieces (or maybe the big lens at the end.just thought of that). This brings me to your next question about why I think I need to replace the eyepieces. I've looked at the moon, Venus and Jupiter. Yes, I can see distant objects through it.if I put one of the eyepieces in it. I do know, however, that my husband's grandfather bought it brand new. I do not know when it was originally purchased. Sure can! Will post them at the end of this reply after I address everyone elseĭo you know when it was originally purchased? Can you see distant objects through it?

they have been known to crack and blind people! Whatever you do, do not be tempted to look at the sun through either the main telescope or the finder, you will certainly injure your vision! These instruments sometimes included a so-called "sun filter", but they are dangerous in the extreme. The telescope tube is attached to what is referred to as an alt-azimuth mounting, which makes it more suitable for viewing distant terrestrial objects than for astronomical observations, although this does not preclude looking at the stars, it just makes it a bit more difficult. The main eyepiece is readily available from various sources in the $20-$30 range, while the finder eyepiece may be a bit more difficult to locate - take a close look in that box, they both may be hidden there. I see it is missing the eyepiece that goes into the right-angle piece on the end of the telescope (referred to as a "star diagonal") as well as the eyepiece at the rear of the smaller finder telescope.
