but there is no cure for aperture fever and you need to regularly recoat mirrors and collimate.

Hmm Everybody seems to really want a refractor - could it be that views through refractors are best? Hmm that may be off topic - at least for this thread.
No problem, new thread. ;-) And define "everybody", lol.
Most people start with either a small refractor or small reflector, then aperture fever sets in. Face it: Aperture is King, and a 12" portable refractor is impractical (and horribly expensive).
Everyone has owned multiple reflectors so once you have that light-bucket, naturally you begin to look to other designs. Later in life, many of us can afford to get that really nice refractor- as a secondary instrument.
They have their advantages. Smaller aperture so not as susceptible to poor atmospherics (subject to debate). Lack of a central obstruction means lower over-all diffraction. For the planets and doubles, a nice refractor is hard to beat.
But for the faint fuzzies, refractors lose out to light-bucket Newts every time. Aperture trumps the refractor advantages, assuming the optical quality being top-notch in both instruments.
I'd much prefer to observe the planets through a 10" or 12" Newt than a nice 6" refractor, solely because the resolution will be much better and the image brighter.
But, to each, his or her own.
I prefer to own both reflectors and refractors. It's telescopes that get my juices flowing. Telescopes. _______________________________________________ Utah-Astronomy mailing list http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy
