By
it, I mean
this!
After a lot of googling (without knowing what to call it), I'm assuming it's a 2" Focuser Adapter?
I mount it onto my telescope and proceed to place either my 10mm 1.25" lens or my 25mm 1.25" lens - yet I can't focus on anything.
What do I do with it? I haven't seen 2" lenses anywhere.
Can I get it to work with my 1.25" lenses?
