Tecnosky achromatic refractor with 152 diameter and 900mm focal length with 2.5 "rack and pinion focuser

Thanks to the large aperture and short focal length this telescope is well suited for deep-sky observation at low magnification; with wide-field eyepieces the Milky Way and open clusters will be composed of thousands of point-like stars like pinheads.

Characteristics of the Tecnosky 152/900:

  • - Doublet air spaced, Ohara K9 and F4 glasses in collimable cell. All surfaces are FMC treated
  • - Aluminum tube with internal diaphragms and perfect opacification. Retractable lens hood with locking knob. It holds even very heavy CCDs perfectly. Long excursion with graduated scale and 3 "thread for Tecnosky giant flattener. 1:10 reduction knob. 2" to 1.25 "adapter with brass locking band included.
  • - great rings with vixen dovetail handle and bar
  • - New version with improved and lighter intubation, only 9.2kg!

Deep sky observations:

certainly one of the main fields are wide-field observations, which give very fine stars and sharp and contrasted images beyond all expectations. Thanks to the 152mm diameter and the ability to withstand magnification up to 300x without significant image decay, you can also observe globular clusters, double stars and planetary nebulae.


The Tecnosky 152 has a superb 2.5 "focuser that allows photographic loads up to 5kg without bending or slipping. No vignetting up to medium format and the possibility of using our TS FLAT flatteners. RGB with a monochrome camera and a UHC luminance filter, which significantly reduces chromatic aberration.

Lunar and planetary observations:

Obviously it would not be the main vocation of this instrument, but it will leave you amazed: observe Jupiter easily up to 200x without any filter and the moon at over 300x. By using a filter such as the Baader semi apo the performance is significantly improved. You will discover new fields of application with this refractor!

The refractor offers amazing color correction thanks to O'Hara's K9 and F4 glasses. The cell is collimable and built with solidity in mind. Furthermore, the lenses are not distorted or unglued during transport and temperature variations.
