Our view

Very popular Celestron telescope with those new to astronomy. Highly portable complete small GOTO telescope with a useful built-in tilt platform that makes a wedge for equatorial mounting. This means the 4SE can be used for longer exposure photography, something the SLT telescopes cannot be used for. The tube assembly has a flip mirror at the rear of the telescope so that it can be moved aside for when a dSLR needs to be attached to the rear port.
Requirements. You will need a 12v DC Powertank or a regulated 230v AC to 12v DC adapter power supply. The SEs can run on AA batteries, but a set of these may only last one night’s observing.


Budget for a power supply, a weak sky pollution filter such as the Baader 1.25 Neodymium, a Neutral density filter or Baader polarising set for the moon. Also budget for a an A4 sheet of Baader Astrosolar for white light solar observation.

With any Cassegrain telescope you will have to consider the affect dew fall. The cheapest solution is a lens hood but when dew is a real problem then heater straps will evaporate dew off.
