Is the Sky-Watcher Skyliner 150P Classic a good first telescope?

Yes if what you mainly want is nebulae, clusters and galaxies, by eye, the moon and the planets: that is what this family does best. No if your priority is sharing it with children, taking it with me: other families do better for the same money. 18 kg: you need to be able to carry it outside, every night, unaided.

What can you see with the Sky-Watcher Skyliner 150P Classic?

Under a suburban sky, from its 150 mm aperture: The Moon (Detailed), Saturn (Detailed), Jupiter (Detailed), The Orion Nebula (Recognisable), The Andromeda Galaxy (Recognisable), The Hercules Cluster (Recognisable). Useful magnification from 25× to 300×.

How much does the Sky-Watcher Skyliner 150P Classic cost?

What it shows, really

These circles are simulations, computed from the aperture, the magnification and the sky — indicative, not exact. A real night also depends on the turbulence, your eyes and your experience. Closer to the truth than the photo on the box; still not a promise.

Under a suburban sky (Bortle 6), through a common 25 mm eyepiece for wide targets and a 10 mm for planets. Every circle is the true field — nothing is enlarged.

Made for

Nebulae, clusters and galaxies, by eye
The classic answer. Aperture is what deep-sky observing is short of, and this is where it stops being expensive.
The Moon and the planets
Plenty of resolution. You will be nudging it along by hand every thirty seconds at high power.
The Sun
In white light: sunspots with their penumbra, faculae near the edge, and granulation on a steady morning. Dawes' limit on the Sun: 0.8″ (116 ÷ 150 mm, arithmetic). Measure the outside diameter first, then one of: Omegon Helievo 152 (144–168 mm), Omegon Helievo 172 (164–188 mm), Omegon Helievo 192 (184–208 mm), euro EMC SF100 (187–221 mm) (€89–€125). Every time: certified filter over the front · finder capped · never an eyepiece filter · an adult with children · never without the filter · measure first.

Not made for

Sharing it with children
The eyepiece height wanders between standing and kneeling as you move around the sky.
Taking it with me
It goes in a car and nowhere else.

The Sun, safely

No solar filter in the box

The Sun with this model

No source we have states the outside diameter of its tube or dew shield. Measure it at the front, then take the cell whose range holds it. For 150 mm of aperture, one of these:

In white light: sunspots with their penumbra, faculae near the edge, and granulation on a steady morning. Dawes' limit on the Sun: 0.8″ (116 ÷ 150 mm, arithmetic).

Past about 100 to 125 mm, daytime air rather than aperture generally sets the limit on the Sun (experience: the AAVSO solar observing guide).

The listing names no standard; no international standard exists for filters on telescopes, binoculars or lenses (AAS).

Every time

A certified solar filter over the FRONT of the instrument, fastened so it cannot slip or blow off.
Cap or remove the finder. It is a second telescope, and it has no filter.
Never a filter at the eyepiece end: the concentrated sunlight there can crack it in an instant.
With children, an adult is there every time.
Never look, or point, without the filter on. Check it before each use; a scratched or torn filter goes in the bin.
Measure before ordering. A cell that sits loose can fall off.

The family it belongs to: 150–200 mm Dobsonian

What it does well

Enough aperture that globular clusters resolve into stars rather than staying fuzz
No mount to align: push it, and it stays where you left it
Nothing electronic to fail at −2 °C

What it costs you

Two trips outside, or one heavy one. This is what decides whether it gets used
The base is bulky in a way the tube is not — storage is the real constraint
Useless on a balcony: it cannot swing past a railing or reach anything high

Worth knowing about this model

The archetype. The instrument every beginners' forum names first, at the price where a first telescope stops being a compromise. 1.2 m long: measure the cupboard.
