I still haven't figured out how to focus the finder scope on my Tasco 17TR. I can unscrew the objective and move it an inch away from the tube and it comes into focus but there seems to be no way to focus it and keep it on the OTA.
I don't know if it's a Towa, it merely states "Made in Japan" 1985 Tasco sales inc.
Edited to add that I just found one for sale at Astromart and can see how it's done.
I took mine completely apart and didn't see that draw tube. I'll have to look again at it but it's not here with me right now.
So far my viewing has been marginal with it, but I need to spend more time with it before passing judgement.
