Sky-Watcher SkyMax 150 Pro + HEQ5

This is a scope that rewards patience and good seeing conditions. At 1800mm focal length and 150mm aperture, planetary detail is genuinely impressive: Jupiter shows multiple cloud belts, festoons, and the Great Red Spot; Saturn reveals the Cassini Division cleanly and banding on the disc; Mars at opposition shows the polar ice cap, dark surface markings like Syrtis Major, and hints of limb brightening. The Moon is spectacular — crater walls, rilles, and the terraced interior of Copernicus are all within reach at high magnification. Double stars split cleanly thanks to the long focal ratio and unobstructed optics; Dawes' limit here is around 0.77 arcseconds, putting tight pairs like Castor and Albireo well within reach, and challenging pairs like Rigel's companion become achievable.

Deep-sky objects are visible but constrained by the narrow field of view. The Orion Nebula's bright core and trapezium stars are well-resolved, but you won't frame the full extent of the nebula. Globular clusters like M13 show granular texture with stars beginning to resolve at the edges. The Andromeda Galaxy shows only the bright core — the 1800mm focal length crops the outer halo entirely. Open clusters like the Pleiades are far too large for the field; smaller, denser clusters like M11 work better.

For imaging, the HEQ5 Pro mount is a proven platform for planetary work with a high-speed camera. The f/12 focal ratio means deep-sky imaging is impractical without a focal reducer, and even then, the narrow field and slow speed make it a poor match for nebulae and galaxies. But for lucky-imaging of planets and the Moon, this setup is excellent — the long native focal length gives large image scale without a Barlow.
