On the other hand, let us not forget why people (including myself) love good refractors:
- more aesthetically pleasing views than Newts or SCTs
- higher contrast (due to no central obstruction)
- no or little cooldown time
- never need collimation
just to list a few. The ED100 would also be well suited to deep sky photography. Here the lack of sensitivity to ambient temperature fluctuations and collimation problems would be a big plus also.
Stu's makes a strong case for the refractor here:
