my first scope (which i bought in feb of last year) was an elcheapo wobbleotronic ebay refractor which for some reason had reasonably good optics and offered ok views. I was thinking of making it into a short-tube by just cutting the tube down and rescrewing the focuser on (which can be done with relative ease(i have checked)).
I just want to know the implications of this. how does it effect the focusing .balance and performance etc?
love playing around with ideas like this
