About the Officina Stellare PRC400 Pro 400mm Ritchey Chretien Telescope…
PROFESSIONAL LEVEL TELESCOPE – Exceptional quality telescope for Advanced & Professional users. Exceptional performance for those that wish to achieve everything. Sublime performance on the moon, planets, stars, double stars, star clusters, globular star clusters, nebulae & galaxies.
The PRC400 Pro 400mm Ritchey Chretien Telescope is supremely crafted, uniquely design RC telescope featuring LK7 (or optional Sitall for ST model) optical glass. It is housed in a zero expansion carbon fiber, open truss tube body embellished with CNC aluminum trim and brilliant clear coat finish. The Pro RC400 has a clear aperture of 400mm and operates at a focal length of 3200mm with an f/8 focal ratio. The overall length of the Officina Stellare Pro RC 400 optical train assembly measures 1100 mm and its overall average weight is 42 kg with an average tube diameter 590 mm. The spot size for the Officina Stellare Pro RC 400 telescope at 26mm from axis with optional flattener is an exceptional 5 microns.
What a beauty…
Telescopes such as the Officina Stellare Pro RC400 Ritchey Chretien are created around the finest quality optics available – each one realised under precise quality requirement conditions, using the highest renewed standards in terms of quality of the materials being used and the production processes involved. Officina Stellare mirror blanks are of certified origin and epitomize perfect homogeneity. They offer, as a standard, very high reflectivity protected aluminised and multi-layer anti-reflexion coating. In terms of customer satisfaction, it is possible to make special coatings (silver, gold etc.) for specific wavelength-related needs. In addition, there is an in-house, pneumatically insulated, 6 meter long and 500 kg weight optical bench using a Zygo mark IV interferometer with phase shifter coupled with a highly sophisticated analysis software for producing extremely precise measurements and tests. Officina Stellare verifies each and every one of their instruments before delivery to the final user.
The materials Officinia Stellare use in their premium quality telescopes include ultra purity single block machined aluminium and carbon fiber because of their lightness, their mechanical and thermal properties, plus optimal resistance to environmental conditions. Mechanical components for the Officina Stellare Pro RC400 are machined using CNC computer assisted machines from full block aluminum to guarantee superior precision. Carbon fiber components are produced following strict specification and tolerances. Each component for Officina Stellare Pro RC400 is computer designed and optimised for the best structural performance.
When it comes to the Officina Stellare Pro RC400 Ritchey Chretien, the holding systems for both mirrors, rings and all the structural components, even the smallest, are CNC machined from a single block special aluminum (6061/7075, Ergal and Anticorodal), stainless steel, titanium and brass. The tubes are made of true carbon-graphite fiber obtained with the use of high vacuum process, allowing Officina Stellare to obtain the best stability of the focus vs. temperature changes while still maintaining the best structural rigidity and lightness.
Significant care is taken in the making of the rear holding cell of the primary mirror for the Officina Stellare Pro RC400 Ritchey Chretien. The entire rear cell for the primary mirror is figured to have the best rigidity/ weight ratio and for the fastest possible thermal stabilization between the environment and mirror. Great attention has been applied to simplify collimation resulting in stable and efficient but easy to use system. The collimation for the Officina Stellare Pro RC400 is accomplished by acting on just three points (the minimum required points to generate a single plane) using a special, great diameter preloaded bolts (one for each point). This results in a single hand use, simply turn the bolt left or right to move the mirror back and forth (no more complicated operations using push pull screws and locks) in a very intuitive way.
Light shields for the primary and secondary mirrors of the Officina Stellare Pro RC400 Ritchey Chretien are computer designed and optimized to ensure complete illumination of the field still maintaining a complete protection from stray light. Inside the light shields there are also micro baffles that reduces, coupled with an opaque painting of the surfaces, to nearly zero any possible parasite stray light. In some cases and for particular applications, the light shield for the secondary mirror is made using a special layout that maintain the efficiency of the system while reducing the obstruction for the system. The back plate of the telescope comes standard with a system for adjusting the planarity of the focal plane in order to compensate for any small misalignment in the imaging train, always unwanted and annoying specially on today’s large CCD cameras.
It doesn’t get any better than this!
