Introducing our new accessory for reflector telescopes, the RB-Focus stainless steel and carbon fiber double vein spider system. It has been possible to reduce considerably the thickness of the veins to only 0.5mm. In addition to reducing weight, while improving the rigidity and stability of the secondary holder. It allows to maintain collimation after prolonged use or transfers to the field, a much more robust system created for all Newtonian-loving astrophotographers, who seek to improve the quality of their telescope and facilitate the use of this optical design.
Avoid collimation changes derived from temperature. This spider being made of the same material that everyone loves for its low weight and high rigidity, it is very resistant to temperature changes; ensuring that, regardless of whether it varies, collimation and focus remain intact.
Contrary to what many imagine, when they see the double vein design and think that the stars will come out with double spikes. By focusing these cancel, producing elongated and fine diffractions that give a stylized touch to the stars, especially for lovers of subtle spikes.
As an added value this design can be used to focus since having the perfect star we are sure that the telescope is in focus.
Improved collimation system, having 4 collimation points, factory bob knobs and a modified clutch system to improve the collimation and alignment process of the secondary installed, the RB-Focus spider makes it much easier to frame the focuser and collimation of the mirror secondary, achieving perfect mirror or diagonal alignments in a few seconds.
