bigger OT for my 127 slt mount

Recommended Posts

hi ladies and gentlemen, i have a few silly questions to ask.

i have a nexstar 127 slt on original fork mount. im wondering what would be the biggest OT  i could put on the mount without stress on the motor or obstruction. im thinking i might be able to put a 6inch tube  that would weigh the same or even better less than the 127 tube? 

2nd question: can anybody tell me if the celestron  x-cel lx x3 barlow is a good enough barlow for the 127 slt ...(for imaging moon and planets with my zwo) ? or would you recommend using a different balow and if so what would yr choice be?  this barlow is a 3 element design and fully MC. 

THANKS CHAPS

A Nexstar 127 is about the  heaviest you can put on that mount.   A 130mm Newt is IIRC the biggest bundled with this mount.
