Hello,
I am fairly new to astronomy. I own a 10" dob. for viewing. Recently was digging around & found an old telescope. I would guess age around 25 to 30 years old. Sticker on scope says: Sears no.49 24071 150 power Achromatic coated lens
F=600mm D=50mm Japan. I took a look at the lens in this & to my surprise it is glass. Two pieces of glass separated by a thin plastic like spacer. My question is; Can I use these lens to make a spotting scope of some sort (terrestial or birding)? Is it worth it or these lens no good since it probaly was a cheap scope? Or maybe make a finder? If it is worth it to make a spotter can I put this in a shorter tube since this one is about 2 feet long. Can someone please point me in the right direction.
Thanks very much for your time in reading this.
