  • The Officina Stellare 600 RiLA Astrograph is a fast telescope with a wide corrected field of view; perfect for imaging with today's large CCD sensors!
  • The 24" f/5 RiLA has a very simple optical system consisting of an aspherical primary and a spherical secondary, plus a special corrector at the back near focus. This low expansion optical set is easy to collimate and produces high resolution images across a wide field.
  • Back focus is 290mm, and the polychromatic spot size at 52mm off-axis is only 6.4 microns.
  • The RILA 600 houses the optics in a carbon fiber/aluminum open truss tube.
  • This OTA package includes two Losmandy-style dovetail bars, manual control on both mirrors, a black fabric shroud and caps.
  • Please Note: Image shows the f/3.8 version of the 600 RiLA Astrograph.

Officina Stellare 600 RiLA Astrograph with Low Expansion Optics and Aluminum-Carbon Truss

Officina Stellare is one of today's leaders in the production of high quality astronomy equipment for the discerning professional or advanced amateur. Their products can be found in observatories around the world, and their high speed tracking lens systems are a relied upon component in the industries of aerospace and defense.

One of the reasons Officina Stellare is so popular today is because they listen to their customers. In fact, the RiLA series of astrographs was created because customers asked for a fast telescope with a very wide, corrected field of view. They wanted something that didn't weigh a ton, but that would accept all of the imagers, rotators, focusers, guiders, and other equipment that makes up the imaging train used by today's astronomer.

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.

The Officina Stellare 600 RiLA Astrograph has an aperture of 24" and a focal ratio of f/5.  The low expansion optics are housed in an aluminum carbon fiber truss tube, and there are Losmandy style dovetails mounted on the truss for mounting versatility. Three ventilation fans are part of the design, which helps the telescope reach ambient temperature as quickly as possible. The mirrors can be heated to keep dew at bay, and depending on the package or accessories you choose, most everything can be electronically controlled via the TC-1.
