    No simple answer...depends on what usage the owner has for his telescope...and a few other things like viewing comfort etc...

    You intend to image...then a Equatorial (GEM) mount is preferred IF you also intend to get into longish exposures then an expensive Gem is preferred or even required...

    If you are visual and like being comfortable as well as being easily able to just point the scope pretty close to your target OR only intend to do short exposure imaging then a Alt/Azm mount may be advantageous


    I'm 66 ...old body, bad knees, bad back, blind in one eye, deaf in the other ear, (I'm perfectly balanced) and I do not image...

    I'll personally take an Alt/Azm mount any day... I do own both types of mounts btw..

    I agree, altaz is better for visual observations, more intuitive to move and definitely lighter in weight. I'd recommend the Vixen Porta or Porta II mount, which is wel built, light, stable, and it has slow motion controls. It costs about 300 US $, but for $ 320-390 they typically throw in a small Vixen telescope, and they're pretty good (L70, A80, or the 110 Mak type, or the R130SF). Each would cost about $ 200 by itself. By the way, I would NOT recommend the Mini Porta, too shakey.

    Here's a telescope with an EQ mount: Celestron AstroMaster 114 EQ
    And this telescope is on a AltAz mount: Celestron NexStar 8 SE

    I've learned that a EQ mount is better for astrophotography. However, an AltAz mount is easier to use and align. Also, you can eventually use an AltAz mount (with or without a wedge) for astrophotography.
    Some AltAz mounts on a wedge can work better than a cheap EQ mount. It really depends on your budget and what you want to do with the mount. A nice GEM mount will cost over $1000.

    Sorry, forgot to mention that I also use a Celestron altaz mount that only costs $ 90. It has slow motion controls and it works not bad, but it is not as functional as the Porta.
