While looking at it yesterday, I was experimenting with what can come off. The red-lined part you referenced does indeed pop right out. It's sorta like a little cap, almost. I wouldn't have considered it an adapter, but, in hindsight, that makes perfect sense.

According to B&H website, the diameter is 1.25.

Last bit of info I know to post (other than measuring when I get my measuring tape) hope this helps further... Thank you ALL!

What's pictured is all I have. No lenses (eye pieces?) came with.

Thanks! I had no idea the whole thing came off! 😂

This is from the box it came in. No other info included. Hope this helps more...

Thank you ALL! Here are a few pics of the telescope. I suppose I should have thought about including photos in my initial post! It's like, "Mr. Mechanic, I know we are on the phone, but my car, don't know the make or model, is making a weird noise! What's wrong with it??" I briefly skimmed the newer comments posted, but I am going to go back and give them the attention they deserve right now. Again, I truly appreciate each of you taking the time to help/encourage me! -Larry

Greetings All! Very Short Explanation: I'm disabled (43) and desperately trying to find ways to still bond/spend time with my youngest son (13). My son expressed an interest, about two months ago, in Astronomy after watching a few YouTube videos on the subject (specifically, the moon and our neighboring planets). He asked if one day we could get a telescope. I was somewhat surprised when, over the course of the following days/weeks, he didn't forget about his request or shift his attention to other, "more 13 year old pressing matters." In fact, he became increasingly MORE excited, despite our lack of progress on the subject (except for many hours of questions and research regarding all things space). So, I decided that somehow, someway, I would discover the means in which to make this dream of his a reality. However, due to our financial situation, I wasn't sure it would ever happen. Well, lo and behold, I stumbled across a Vivitar 76700 Reflecting Telescope, while killing time before a drs appt, at the local Goodwill, for only $14.99. I immediately withdrew my "Emergency $20" from my wallet, and I purchased it! When I finally arrived home, I began the process of putting it together. Unfortunately, I soon discovered that it lacked everything which is placed in the "lens hole/slot" on the top, back of the telescope (just a hole, no lens, barrel, or anything originally included to fill said hole. !!!EDIT/CORRECTION!!!: It DOES have the piece which screws onto the side of the telescope that has "adjustor knobs" below it for, I'm assuming, extending/retracting the lens(?). There is just nothing INSIDE this piece except a hole/space. Sorry! This is our youngest son (13), who is a "loner." He is very quiet/shy/lacks self-confidence, and suffers from mental/learning disabilities, but truly is "sharp as a tack" in many, many ways. So, when we discover something, anything, educationally speaking, that peaks his interest, we try our hardest to encourage him! Now, I don't really have any/much money to spend on getting this telescope in complete working order (I am NOT asking or soliciting for ANYTHING!!) , but I refuse to pass up this chance to bond with him, encourage this budding passion for Astronomy, and help get him OFF that blasted PlayBoxCube more frequently, and into something more beneficial for his young, developing mind! Now to my question(s)... What further (inexpensive) equipment would suffice in completing his new-to-us telescope, and increase his allure to the wonders awaiting his discovery in the heavens above? Quality vs Price? Trade-offs? On-topic/slightly off-specific-topic advice? Links, articles, groups, periodicals, videos...ANY suggestions gratefully welcomed! Thank you, in advance, for indulging my attempted-to-be-brief background/relevant personal info, and for taking the time to help this guy be a (better) dad again. I feel blessed to have found this particular site/group. Live Long & Prosper, -Larry
