Sky-Watcher SkyMax 180 Pro
A 180mm f/15 Maksutov-Cassegrain built for high-resolution planetary and lunar observation, with the long focal length and clean optics to exploit excellent seeing conditions.

What you'll see
This is a specialist high-magnification instrument. On nights of good seeing, planetary views through the SkyMax 180 Pro are among the best available from a production telescope. Saturn shows the Cassini Division cleanly, the globe's shadow on the rings, and subtle banding on the disc itself. Jupiter reveals individual festoons, barges in the belts, and the Great Red Spot with genuine internal structure. Mars at opposition shows dark albedo features, the polar cap, and occasionally limb clouds. The Moon is breathtaking — Hadley Rille, the Straight Wall, and tiny craterlets inside larger formations are all within reach at 200–300× on a steady night.
Deep sky is not this scope's strength, but it's not useless either. Globular clusters like M13 are partially resolved across the face with a granular, sparkling appearance. Planetary nebulae — M57 (Ring Nebula), M27 (Dumbbell) — are small but well-framed at this focal length, with the Ring's annular shape clearly defined. Bright galaxies like M81/M82 show their cores, but extended nebulosity and large objects like M31 are severely cropped by the narrow field.
The extremely narrow true field of view (roughly 0.3° with a typical 25mm eyepiece) means finding objects manually is difficult. The GoTo capability of the recommended mounts is essentially mandatory, not optional. This is a scope that rewards patience, excellent alignment, and steady skies — and punishes turbulence and poor collimation ruthlessly.
Worth knowing before you buy

2700mm focal length means an extremely narrow true field of view (roughly 0.
At f/15, the scope has very long cool-down times; the sealed Maksutov corrector plate traps tube currents, and 45–90 min…
