What it does well

  • Tracks accurately enough for exposures measured in minutes
  • Everything else in the hobby can be bolted to a good mount later
  • The results are genuinely spectacular, and genuinely earned

What it costs you

  • 45 minutes of setup before the first frame, every night
  • A steep learning curve involving guiding, calibration frames and processing software
  • Buying the telescope before the mount is the classic and expensive mistake

Fit against each goal

  • Serious deep-sky imaging · 5 out of 5

    The mount is the instrument. Everything else is negotiable.

  • First astrophotography · 2 out of 5

    It works, but it is a great deal of machinery to learn on.

  • Nebulae, clusters and galaxies, by eye · 2 out of 5

    Small aperture, visually modest, on a mount that makes visual observing awkward.
