Sky-Watcher Stargate 400P SynScan GOTO Dobsonian Telescope
$8,429.00
16 inch optics on a SynScan GoTo mount.
The Sky-Watcher Stargate 400P SynScan GoTo is a Newtonian telescope for visual astronomy. Its aperture suits lunar detail, planets, star clusters and deep-sky observing; darker skies make faint targets easier to see.
16 inchaperture
Collect light for visual observing
The parabolic primary mirror forms the image you view through an eyepiece. Sky conditions still set the detail you can resolve.
1650 mmfocal length
Choose magnification with the eyepiece
Magnification is telescope focal length divided by eyepiece focal length. Start at low power to find and centre a target, then increase it when the air is steady.
GoTomount
Motorised finding and tracking
Align the telescope first, then select a target for the mount to locate and track.
Pack the truss structure in sections
The truss structure separates for transport and is assembled at the observing site. Plan the handling of the optical assembly and base before travelling; this is a large telescope, even when packed down.
Using the Stargate 400P SynScan GoTo
Manual movement between targets
Freedom Find dual encoders let you move the telescope manually while retaining its alignment.
Observing conditions
Let the optics approach the outdoor temperature. Steady air and a dark observing location help you make the most of the aperture.
Good to know
Plan the handling
Allow space for assembly and clear access around the telescope. Check that you can safely move and store the large optical assembly and base.
Prepare the optics
Allow cooling time before judging fine detail. Check reflector collimation, particularly after transport or assembly.
Keep the Sun out of the telescope
Never point the telescope or finder at the Sun. Unfiltered sunlight can cause permanent eye damage.
