Sky-Watcher Skymax 127 SynScan GoTo vs Vixen VMC110L
The Sky-Watcher Skymax 127 SynScan GoTo is a complete setup. The Vixen VMC110L needs a mount before it's usable.
First light
Sky-Watcher · 127mm · £399
The automated deep-sky platform
- 127mm maksutov-cassegrain 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
- 7.5kg total — requires a fixed garden spot or car transport
Vixen · 110mm · £599
The custom-rig optical tube
- 110mm maksutov-cassegrain — optical tube only, no mount included
- 1035mm focal length at f/9.4
- 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 Skymax 127 SynScan GoTo gathers 1.3× 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
Sky-Watcher Skymax 127 SynScan GoTo's longer focal length reaches higher magnification with the same eyepiece — better reach for planetary detail. Vixen VMC110L's shorter focal length gives a wider true field — better for large open clusters and extended nebulae.
Focal ratio
Vixen VMC110L's faster f/9.4 delivers wider fields with any eyepiece — better for open clusters and large nebulae. Sky-Watcher Skymax 127 SynScan GoTo's f/12.1 provides more magnification per eyepiece — better for fine planetary detail.
Mount type
Vixen VMC110L has no mount — add a compatible mount before you can observe. Sky-Watcher Skymax 127 SynScan GoTo is a complete ready-to-use system.
Weight (OTA)
Vixen VMC110L's optical tube is 1.9kg lighter. Relevant if you plan to use it on multiple mounts or carry the tube to dark-sky sites separately.
Optical design
Both Maksutov-Cassegrains — compact tubes, long focal length, excellent planetary contrast. Performance differences come from aperture and mount, not optical formula.
At the eyepiece
Sky-Watcher
Sky-Watcher Skymax 127 SynScan GoTo
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 clear structure — nebulosity spreading around the Trapezium, which splits at moderate power. The Andromeda Galaxy (M31) shows a concentrated core clearly. The Hercules Cluster (M13) shows some resolution at the edges at higher magnification.

The real tradeoff
Both scopes are capable. The question is which one fits the way you actually observe.
The Sky-Watcher Skymax 127 SynScan GoTo is a complete package — everything arrives in one box and you can observe the same day. The Vixen VMC110L 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 Sky-Watcher Skymax 127 SynScan GoTo is the practical choice.
The dark side
Every scope has a personality. Here’s where each one gets difficult.
Sky-Watcher
Sky-Watcher Skymax 127 SynScan GoTo
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.
Vixen
Vixen VMC110L
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
Sky-Watcher · Sky-Watcher Skymax 127 SynScan GoTo
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
- You want objects to stay centred at high magnification without having to manually nudge the scope every few minutes
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
The custom-rig optical tube
Vixen · Vixen VMC110L
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 Vixen VMC110L is a bare optical tube. You cannot use it without a separate mount — which adds meaningful cost and complexity. The Sky-Watcher Skymax 127 SynScan GoTo is a complete, ready-to-observe package.
For most buyers, the Sky-Watcher Skymax 127 SynScan GoTo is the right choice — you can observe the same night it arrives. The Vixen VMC110L 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 Sky-Watcher Skymax 127 SynScan GoTo, without hesitation.
