ISTAR OPTICAL produce an extensive range of exciting refractors in achromatic and apochromatic formats - ultra high quality lenses, all with interferometer test report, at down to earth prices.
Tube Assemblies
All ISTAR OTAs use aircraft grade magnesium alloy tubing of 3mm wall thickness, providing strong and very rigid support. The fully baffled tubes are matt black texture powder coated for durability, and come with a lens cap.
The fully adjustable push-pull lens cells and other tube fittings are CNC machined from titanium magnesium alloy, with either a polished natural finish or anodised with colour dependant on product type.
Note that above prices for Perseus range are for the bare OTA without focuser.
A choice of focusers is offered - Istar, Moonlight, Starlight Feather Touch, or Baader SteelTrack, all in 2inch fitting.
Other ranges are fitted with Istar's own high quality, dual speed Crayford-style 2inch focuser, available separately at £215 to include backplate.
Finder units are optional extras, and we will either supply Peak2valley's own design 65mm superfinder ( £195) or brand of your choice. The Moonlight focuser comes with finder dovetails as standard, otherwise finders would be fitted directly to the main tube.
