Sandwich primary mirror
The ventilated sandwich design promotes cooling. A mirror close to ambient temperature reduces one source of image-softening air currents.

Hubble Optics 24 Inch Premium Ultra Light Dobsonian Telescope
$21,190.00
A 24-inch mirror with a compact f/3.3 optical layout.
The Hubble Optics UL24 is a 609.6 mm parabolic reflector for experienced observers with a practical plan for handling a large telescope. Its f/3.3 layout keeps the focal length to approximately 2012 mm, while the truss and folding altitude bearings allow disassembly.
Folding altitude bearings support a large visual telescope.
The UL24 uses a mirror box, eight sectional trusses and folding altitude bearings. These parts support disassembly, but the manual configuration still weighs approximately 70 kg assembled. Plan the route, lifting help and observing position before moving it.
Illustrative UL24 setup with optional finder and grips. Control hardware depends on the selected version.
How the UL24 supports and focuses the image.
18-point mirror support
The flotation cell distributes the rear support of the primary mirror. Lateral support and collimation are separate, so alignment does not rely on distorting the mirror edge.
Dual-speed focusing
The 2-inch linear-bearing Crayford focuser gives you coarse adjustment followed by fine focus. Eyepieces are selected separately to suit the targets and magnifications you use.
Choose how you find and follow objects.
Manual
Locate targets yourself and move the telescope by hand.
- PointingBy hand
- Following an objectBy hand
Guided Push-To
Digital position guidance helps you locate a target; you still move the telescope yourself. Push-To does not add motorised tracking.
- PointingGuided, moved by hand
- Following an objectBy hand
Automatic Go-To
After setup and alignment, the drive moves to selected objects and follows them as the sky turns. A suitable power source is required.
- PointingMotorised
- Following an objectMotorised
These are separate Telescope Control choices. Compatible hardware and software are required for phone or tablet control. Power requirements depend on the supplied control system.
Plan the space and handling.
Assembled weight, Manualapproximately 70 kg
Eyepiece height at zenithapproximately 1955 mm
Manual telescope figures exclude added control equipment and observing accessories. Plan carrying, storage and eyepiece access for your chosen configuration.
Good to know.
Choose eyepieces and finder separately
Eyepieces and a conventional optical finder are not included. Shrouds and other light-control accessories are separate options.
Check collimation after assembly
Collimation aligns the mirrors. Check it after reassembly and before observing. UL24 assembly and setup manual.
Keep this telescope away from the Sun
Never point the telescope or finder at the Sun without the correct purpose-made solar protection. Unfiltered viewing can cause permanent eye damage.
