Our view

The SLT to choose for those pinpoint star images and wide-field star clouds. The102 is a short focal ratio achromatic refractor, and thus ideal for low to medium power views of deep-sky objects. Because of the refracting objective and short focal ratio, this telescope performs at its best showing the brighter deep-sky objects in good contrast against the background sky. It makes an ideal telescope for an introduction to visual astronomy. It can also be used successfully as a white light solar telescope by adding Baader Astrosolar film over the full aperture.
Requirements. You will need a 12v Powertank or a 230v AC to 12v DC adapter power supply. This will need to be tip positive and regulated. The SLT mounts are designed to work from AA alkaline batteries, but because of the amp draw during full slew of the motors, they may only last for one nights observing, such is the nature of small batteries, particularly in temperatures close to zero.


Budget for a power supply, a weak light pollution filter such as the Baader 1.25” Neodymium filter, an A4 sheet of Baader Astrosolar, a single 1.25” Baader polarizing filter and a wide-angle eyepiece (something with a wider apparent field than about 60 degrees).
