Product Description

The Officina Stellare Rila Series are known for having a fast focal ratio with a wide corrected field of view while maintaining a lightweight body. The apertures range from 300mm all the way to 800mm. The Rila 800 has a f/5 focal ratio.

Once Officina Stellare decided they would make this dream telescope a reality, they put Italian optical designer, Massimo Riccardi, on the job. Riccardi wanted to create a telescope that had the following characteristics:

  • It had to be a fast system.
  • The design needed to be compact and lightweight for its aperture.
  • It would have the least number of surfaces possible while still producing a large corrected field.
  • The secondary obstruction would be as small as possible.
  • These features were made a reality and then some with the creation of the Officina Stellare RiLA (Riccardi Large Astrograph) Series. The design, which is a modification of the Harmer-Wynne, has an aspherical primary and a spherical secondary. A special corrector is placed just before focus. The RiLA is corrected in the visible near IR range, with more than 80% of its energy focused in a 4-6 micron RMS spot.

A wide range of apertures is available, starting at 300mm and topping out at 800mm. The optics are housed in a zero expansion aluminum carbon tube system and there are Losmandy style dovetails mounted on the truss for mounting versatility.
