Telescopes

ISTAR OPTICAL produce an extensive range of exciting refractors in achromat and anastigmat formats - ultra high quality lenses  at down to earth prices.

 

SEE SPECIALS BELOW!

 
Tube Assemblies - all prices subject to confirmation at time of order due to currency fluctuations.
 
Availability - Istar have anounced that production of all OTAs will be phased out this year, with only lenses being readily available.
 
We are able to quote for a bespoke OTA for special order.
 
All ISTAR OTAs use aircraft grade magnesium alloy tubing, providing strong and very rigid support. The fully baffled tubes are powder coated for durability, and come with a lens cap. Dewshields now are retractable, some with a bayonet locking system.
 
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.

NEW FOR 2016 - Moonlite dual speed rack and pinion 2" focuser on all OTAs as standard. 
 
However, a choice of focusers is offered - Moonlite, Starlight Feather Touch, or Baader SteelTrack, all in 2inch fitting.
 
Finder units are optional extras, and we would recommend the Teleskop Services, APM range or brand of your choice. 

Anastigmatic lens options - Rx technology

This optical arrangement yields near ED performance but with the major benefits of lower lens weight and faster cool down time than triplets - and considerable cost savings.

" ..the rich field obsever's dream ticket..."  " ...I trained the instrument on delta Cygni and was impressed to have glimpsed the companion."
 
" ... I was deeply impressed to fit the entire Pleiades cluster into the field of view!"   Neil's review is very complementary on all counts.
