I bought this spotting scope a couple years ago. I admittedly do not know much about it. It’s an older model extendable scope. It’s a 20-60 power CT85. I’m happy to do my best at answering questions, but like I said I don’t much about it. I’m not a big fan of spotting scopes so I carried this a lot, but always just use my 15x56 binos to glass. $500 obo and I’ll ship to the lower 48.
