Telescope Comparison
Orion AstroView 90mm EQ Refractor vs Sky-Watcher Evostar 80ED + HEQ5 Pro
One finds objects for you. The other makes you learn the sky — and gives you more aperture in return.
First light
Orion · 90mm
The sky-learner's equatorial scope
- 90mm refractor on a manual equatorial mount
- Good for: Moon, planets, bright star clusters and nebulae
- Setup includes rough polar alignment before observing — more steps than a simple alt-az
- Mount axes feel counterintuitive at first; users find they become natural after several sessions
- Keeps the door open for adding tracking motors and moving into astrophotography later
Sky-Watcher · 80mm · £690
The automated deep-sky platform
- 80mm refractor 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
- 22.5kg total — requires a fixed garden spot or car transport
The full picture
The numbers that separate these two scopes — and what they mean at the eyepiece.
Aperture
Orion AstroView 90mm EQ Refractor 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
Orion AstroView 90mm EQ Refractor's longer focal length reaches higher magnification with the same eyepiece — better reach for planetary detail. Sky-Watcher Evostar 80ED + HEQ5 Pro's shorter focal length gives a wider true field — better for large open clusters and extended nebulae.
Focal ratio
Sky-Watcher Evostar 80ED + HEQ5 Pro's faster f/7.5 delivers wider fields with any eyepiece — better for open clusters and large nebulae. Orion AstroView 90mm EQ Refractor's f/10.1 provides more magnification per eyepiece — better for fine planetary detail.
Mount type
Sky-Watcher Evostar 80ED + HEQ5 Pro adds GoTo — it finds any target in its database after alignment. Orion AstroView 90mm EQ Refractor requires manual navigation.
Weight (OTA)
Similar optical tube weight. Any portability difference between these setups comes from the mount, not the tube itself.
Optical design
Both are refractors — no mirrors to collimate, good contrast, colour-free stars with ED or APO glass. The differences between them are in aperture, focal ratio, and glass quality.
At the eyepiece
Orion
Orion AstroView 90mm EQ Refractor
At moderate magnification, Saturn's rings are cleanly separated from the disk. Jupiter shows two equatorial cloud bands and four Galilean moons. The Moon rewards extended sessions at the eyepiece — the terminator is full of crater and highland detail. The Orion Nebula (M42) is bright and structured, the Trapezium straightforward to split. Open clusters are excellent — the Pleiades, the Double Cluster in Perseus, M35 in Gemini. The Andromeda Galaxy (M31) shows a clear bright core. The longer focal ratio gives the sharp, high-contrast images that quality refractors are known for — planetary detail and pinpoint stars with a good eyepiece.

The real tradeoff
Both scopes are capable. The question is which one fits the way you actually observe.
The Sky-Watcher Evostar 80ED + HEQ5 Pro handles object location automatically — align once, then it slews to anything in its database. The Orion AstroView 90mm EQ Refractor asks you to navigate by star-hopping with a finder scope and sky chart.
For most beginners in light-polluted areas, GoTo removes the biggest early frustration: not being able to find anything. Choose the Orion AstroView 90mm EQ Refractor if learning the sky manually is genuinely part of what you want from the hobby.
The dark side
Every scope has a personality. Here’s where each one gets difficult.
Orion
Orion AstroView 90mm EQ Refractor
Mount axes feel counterintuitive at first
An equatorial mount does not move up/down and left/right as you expect — it follows the rotation of the sky. Users consistently report that it takes several sessions before it begins to feel natural.
Sky-Watcher
Sky-Watcher Evostar 80ED + HEQ5 Pro
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.
Not a spontaneous telescope
At 22.5kg total, this goes out when you plan to go out — not for a quick look on a clear evening.
Which is right for you?
Two different buyers. Two different right answers.
The sky-learner's equatorial scope
Orion · Orion AstroView 90mm EQ Refractor
You’ll love this if…
- You want to understand how an equatorial mount works — and you're prepared to spend a few sessions on polar alignment before it becomes second nature
- You plan to observe from a fixed spot in the garden, where the mount can stay roughly polar-aligned between sessions
- Astrophotography is on your radar even if you're not starting there — this mount keeps that option open with a motor drive upgrade
This will frustrate you if…
- You find the equatorial mount's axes feel wrong — objects move in unexpected directions and polar alignment adds a step each session that takes several outings to become automatic
The automated deep-sky platform
Sky-Watcher · Sky-Watcher Evostar 80ED + HEQ5 Pro
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 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
Our verdict
The Orion AstroView 90mm EQ Refractor is designed to get a new observer to the eyepiece quickly with minimal friction. The Sky-Watcher Evostar 80ED + HEQ5 Pro assumes you already know what you want from the sky, or are genuinely willing to put in the learning time.
If this is your first telescope, buy the Orion AstroView 90mm EQ Refractor. You'll spend a year learning what you actually want, and those lessons are cheaper at its price point. The Sky-Watcher Evostar 80ED + HEQ5 Pro is the scope to buy when you've outgrown your first one and know exactly why you want it. If I had to choose for a first-time buyer: the Orion AstroView 90mm EQ Refractor.
