<<So, what is the appeal?>>
Portability, super quality image, minimum cool down time, contrast,
splitting and measuring double-stars refractor is the best, large aperture
scope more sensitive for atmospheric disturbances, refractor has the largest
field of view for visual or photo purposes etc...
Primarily for CCD photography, since the advance in technology and
affordability of CCD's, you don't need a large aperture telescope, which
require heavy large mount, to take excelent images of DSO's..
