Hubble Optics 12 Inch Premium Ultra Light Dobsonian Telescope
$4,890.00
A 12-inch Dobsonian that breaks down for travel.
The Hubble Optics UP12 is a 304.8 mm parabolic reflector for visual observers who need a telescope that packs down between sessions. Its f/4.5 optics and aluminium structure put the emphasis on usable aperture and compact storage.
Pack down the structure for the next observing trip.
The two-section truss design lets the UP12 break down into smaller components. Packing it safely matters as much as packed size: a luggage case and packing foam are separate accessories. Check your carrier's size and weight limits before travelling.
Packing example with optional luggage case and packing accessories. Finder and eyepieces are not included.
How the UP12 supports and focuses the image.
6-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 14.5 kg (32 lb)
Eyepiece height at zenith1320 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. UP12 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.
