The XT10 is the largest of the non-computerized, black-tube XT scopes, with more or less just a scaled-up design of the smaller ones. Let’s delve into the scope’s features now, shall we?
Overview
Optics
The XT10 is a 10” f/4.7 Newtonian. This moderately fast focal ratio means that collimation is more challenging and the tolerances are lower, but, more importantly, it doesn’t perform as well with cheap eyepieces. A wide-field eyepiece which works moderately well in an f/6 or longer telescope is disastrous in the XT10. To get the most out of this scope, plan on spending at least a few hundred bucks on eyepieces.
