Context: I found a National Geographic HT114CF at goodwill for $5 with basically everything missing except the scope body itself so I said “what the hell, it’s 5 bucks” and now I wanna fix it up. I have a tripod and I have a custom adapter coming for it, but I need to know if this eyepiece adapter will fit both it and my existing lenses from my first scope, a Gskyer D 75mm F1 400mm. Any other questions for more context feel free to ask in the comments. I am fairly new to astronomy and especially the more technical side.
