Hi Brian,
Some of the best on the planet in fact. Astrophysics EDF 155/F7, Astrophysics EDF 160/F7.5, Takahashi TOA 150/F7.3, Takahashi FS 152/F8
The Tak FS152 is a flourite doublet and not quite to the standard of the other 3 which are triplets, but it's still a very fine telescope in every sense of the word.
The views in the 6" refractors are aesthetically nicer and for want of a better term "cleaner" than the views in a 10" newtonian, but they cannot match the larger telescope for resolvable detail, when conditions are favourable, seeing is good and the newtonian properly cooled and collimated. The view in the newtonian is a little bit "rougher" than the views in the refractors, due to the effects of diffraction, but it has more detail to offer, if you are prepared to spend the time on the image. That is simple physics.
Cheers,
John B
