Telescope Comparison
Meade LX85 8" Newtonian vs Sky-Watcher Quattro 250P
The Meade LX85 8" Newtonian is a complete setup. The Sky-Watcher Quattro 250P needs a mount before it's usable.
First light
Meade Instruments · 203mm · £1,099
The automated deep-sky platform
- 203mm newtonian reflector on a computerised mount with motorised tracking
- Good for: Moon, planets, bright nebulae, star clusters, and deep-sky objects
- GoTo system finds any object in its database after initial star alignment — no star atlas needed
- Tracking motors keep objects centred as Earth rotates — useful above 100×, essential for photography
- 22kg total — requires a fixed garden spot or car transport
Sky-Watcher · 254mm · £999
The custom-rig optical tube
- 254mm newtonian reflector — optical tube only, no mount included
- 1000mm focal length at f/3.94
- Requires a compatible mount before you can observe anything
- Best for: observers who already own a suitable mount or are building a specific imaging rig
- Not a complete purchase — budget at least £100–300 extra for a mount before observing
The full picture
The numbers that separate these two scopes — and what they mean at the eyepiece.
Aperture
Sky-Watcher Quattro 250P gathers 1.6× more light. On bright targets — Moon, Saturn, Jupiter — you won't notice. On fainter targets — dim galaxies, faint globular clusters — the gap is real.
Focal length
Meade LX85 8" Newtonian's longer focal length reaches higher magnification with the same eyepiece — better reach for planetary detail. Sky-Watcher Quattro 250P's shorter focal length gives a wider true field — better for large open clusters and extended nebulae.
Focal ratio
Sky-Watcher Quattro 250P's faster f/3.94 delivers wider fields with any eyepiece — better for open clusters and large nebulae. Meade LX85 8" Newtonian's f/5 provides more magnification per eyepiece — better for fine planetary detail.
Mount type
Sky-Watcher Quattro 250P has no mount — add a compatible mount before you can observe. Meade LX85 8" Newtonian is a complete ready-to-use system.
Weight (OTA)
Meade LX85 8" Newtonian's optical tube is 5.1kg lighter. Relevant if you plan to use it on multiple mounts or carry the tube to dark-sky sites separately.
Optical design
Both are Newtonian reflectors — the same optical formula. Any performance difference comes from collimation quality, focal ratio, and eyepiece choice, not the design itself.
At the eyepiece
Meade Instruments
Meade LX85 8" Newtonian
The Moon fills the field at low power with more detail than you'll have time to explore on any given night. Saturn's rings are unmistakable from the first session; in good seeing, the Cassini Division — the dark gap between the A and B rings — is a genuine target at higher magnification. Jupiter shows two equatorial cloud bands clearly, the four Galilean moons changing position night to night. The Orion Nebula (M42) shows wide nebulosity with the Trapezium splitting cleanly into four points at 80×. The Hercules Cluster (M13) begins to resolve into individual stars at the outer edges at higher magnification. The Andromeda Galaxy (M31) fills a wide-field eyepiece; the bright core and inner disc are obvious, and on a dark night the dust lane becomes visible with careful looking.

The Sky-Watcher Quattro 250P gathers 1.6× more light than the Meade LX85 8" Newtonian — a difference that's marginal on bright targets but visible on fainter ones: dimmer galaxies, faint globular clusters, and extended nebulosity that sits below the threshold of the smaller aperture.
The real tradeoff
Both scopes are capable. The question is which one fits the way you actually observe.
The Meade LX85 8" Newtonian is a complete package — everything arrives in one box and you can observe the same day. The Sky-Watcher Quattro 250P is a bare optical tube that needs a separate compatible mount before you can point it at anything, adding significant cost and complexity. Unless you already own a suitable mount, the Meade LX85 8" Newtonian is the practical choice.
The dark side
Every scope has a personality. Here’s where each one gets difficult.
Meade Instruments

Alignment required every session
GoTo star alignment cannot be skipped — the mount needs to know where it is pointing before it can find objects. This adds several minutes to the start of every session, every time.
Collimation: the skill nobody mentions in the listing
The mirrors go out of alignment with use. Stars look bloated rather than sharp when this happens. Users report that a Cheshire eyepiece makes collimation straightforward once learned, but most beginners don't discover they need it until their second or third month.
Not a spontaneous telescope
At 22kg total, this goes out when you plan to go out — not for a quick look on a clear evening.
Sky-Watcher
Sky-Watcher Quattro 250P
No mount included
You cannot observe until you buy a separate compatible mount — add at least £100–300 before you have a working telescope.
Nothing to look through on day one
Until a mount arrives, the optical tube is a piece of glass you cannot point at the sky.
Which is right for you?
Two different buyers. Two different right answers.
The automated deep-sky platform
Meade Instruments · Meade LX85 8" Newtonian
You’ll love this if…
- You want to navigate straight to targets without a star atlas — align once and the scope slews to any object in its database on demand
- You observe from a light-polluted garden where star-hopping to faint deep-sky objects would take most of a clear night
- Astrophotography is where you're headed — the tracking equatorial mount is the essential first component of any imaging setup
This will frustrate you if…
- You find the star alignment required at the start of every session frustrating — GoTo alignment cannot be skipped, and several minutes on a cold night before you can observe is the reality
- You notice that stars look bloated rather than sharp and don't know why — users report this is usually a collimation issue that's straightforward to fix once you know about it, but the listing doesn't mention it
- You want to take it out for spontaneous sessions — at this weight, getting it in and out of a car on your own requires planning and ideally a second pair of hands
The custom-rig optical tube
Sky-Watcher · Sky-Watcher Quattro 250P
You’ll love this if…
- You already own a compatible equatorial or alt-az mount — this is the optical tube you've specifically chosen to put on it
- You're building an imaging rig piece by piece and know exactly what you need at the end of a focuser
- Choosing an optical tube independently of the mount gives you more flexibility over your overall system
This will frustrate you if…
- You buy it without fully accounting for the mount — add at least £100–300 to the purchase price before you have a working telescope
- You expected a complete package and didn't realise this is a bare optical tube that cannot be used without a separate mount
Our verdict
This comparison has a catch: the Sky-Watcher Quattro 250P is a bare optical tube. You cannot use it without a separate mount — which adds meaningful cost and complexity. The Meade LX85 8" Newtonian is a complete, ready-to-observe package.
For most buyers, the Meade LX85 8" Newtonian is the right choice — you can observe the same night it arrives. The Sky-Watcher Quattro 250P makes sense if you already own a compatible mount, or are deliberately building a specific imaging setup piece by piece. If I had to choose for a first telescope: the Meade LX85 8" Newtonian, without hesitation.
