StellaLyra · 10-inch f/5 Dobsonian
Go deeper into the sky you already love.
When you are ready to spend more time with star clusters, nebulae and faint galaxies, aperture becomes a compelling reason to move up. The StellaLyra 10-inch puts a 254mm parabolic mirror on a manual Dobsonian base, with the accessories to start observing straight away.
Choose it for immersive visual astronomy, patient exploration and nights when a darker sky lets a larger telescope show its worth.
Is the 10-inch the right step up?
This is a substantial telescope for someone who can comfortably move and store it. Its appeal is the extra light available for observing, with a familiar solid-tube setup and direct, hands-on control.
Before choosing it over a smaller Dobsonian, think about your normal evening: where it lives, how far you carry it and whether you can take it to darker skies. The telescope you use often will reward you more than one that is difficult to get outside.
Give familiar targets another look.
A larger aperture is a reason to revisit objects, rather than simply race through a longer target list. Spend time at a cluster’s edges, compare the brighter and fainter regions of a nebula, or look for a galaxy’s outline against the background sky.
The result depends on sky brightness, transparency and experience. Dark adaptation and shielding your eyes from nearby lights help; long-exposure photographs remain very different from what you see directly.
Small focus adjustments, useful control.
The 2-inch Crayford focuser provides a 10:1 fine control. Bring your target close to focus, then make smaller adjustments until the detail settles.
At higher power, give yourself time to distinguish poor focus from unsteady air. Use a crisp lunar edge or a star near your target as a reference, and avoid chasing every brief shimmer with the focus knob.
Find the field, then explore it.
An 8×50 right-angle, correct-image finder helps you aim the main telescope. Its upright view is useful when moving between recognisable star patterns on a chart.
Align the finder before observing, then begin with the lowest-power eyepiece. Once your target is centred, change eyepieces to explore the view in more detail. This is a skill you can build gradually, starting with bright, easily identified objects.
Set the movement to suit your eyepiece.
Adjustable altitude tension and tube balance help you accommodate changes in accessories. The base rotates horizontally while the tube moves up and down.
Follow your target with gentle nudges. There is no motorised tracking or GoTo, so practise at low power before moving to closer views, where objects drift across the field more quickly.
Prepare the optics for a good night.
The rear cooling fan helps the primary mirror approach outdoor temperature. A battery holder is included; batteries are separate.
Set up ahead of your planned high-power observing. A mirror that is still cooling can soften the view, even when focus and alignment are correct.
The rear knobs adjust mirror alignment, known as collimation. Plan for a suitable collimation tool and learn to check alignment, particularly after transporting the telescope.
Three eyepieces to get you started.
The included set gives you a practical progression from locating an object to inspecting it more closely. Start with these before deciding where an extra eyepiece would improve your own observing.
| Eyepiece | Power | Suggested use |
|---|---|---|
| 30mm 2-inch SuperView | 42× | Finding targets and wider fields |
| 15mm 1.25-inch Plössl | 83× | Clusters and lunar exploration |
| 9mm 1.25-inch Plössl | 139× | Planets and smaller details |
Magnifications are rounded from the 1250mm focal length. If more power gives you a larger but softer image, return to the lower-power eyepiece.
Your observing package
- Optical tube and flat-pack Dobsonian base
- 8×50 right-angle correct-image finder
- 30mm, 15mm and 9mm eyepieces
- 2-inch to 1.25-inch adapter and 35mm focus extension
- Cooling fan and battery holder
A separate mount is not required. A collimation tool, observing chair and red torch are useful additions.
Measure the route from storage to sky.
The optical tube alone weighs 15.5kg and is wide enough to deserve careful planning around doors, stairs and car space. Carry the tube and base separately, within your own lifting ability. Avoid treating the assembled telescope as a single lift.
| Design | Newtonian reflector / manual Dobsonian |
|---|---|

| Focal ratio | f/4.92 (nominal f/5) |
| Tube length / diameter | 1210mm / 305mm |
| Optical tube weight | 15.5kg |
| Base height / diameter | 640mm / 540mm |
Questions before choosing a larger Dobsonian
Will the 10-inch make a good planetary telescope?
It can serve both planetary and deep-sky interests. For fine planetary detail, careful alignment, thermal settling and steady air matter. Plan to observe when the planet is clear of nearby roofs and reasonably high in the sky.
Is an 8-inch easier to live with?
Its smaller tube can be a better fit when storage, lifting or frequent travel are the deciding factors. Choose the 10-inch when the larger instrument is practical for you and you want to prioritise aperture. The extra size is a real part of the decision.
Do I need more accessories immediately?
Start with the included eyepieces and learn the telescope. Check mirror alignment with a suitable tool, then let actual observing guide later purchases. Comfort and a clear plan for finding targets are often more useful at first than chasing extreme magnification.
Can it replace an astrophotography setup?
This manual mount is intended for visual observing and does not track the sky for long-exposure deep-sky photography. Contact us before choosing it if imaging is your main aim.
Availability reflects supplier stock and can change. Contact Dark Clear Skies to confirm dispatch timing if you need the telescope by a particular date.
