Astrograph Telescopes

For serious astrophotographers, an optical tube that has quality optics and suitable specifications is key to producing successful images. Astrographs come in many different specifications and designs, so each model can be oriented or preferred for a different type of imaging (eg. solar, terrestrial, deep sky etc). Some common designs include the Ritchey-Chrétien, Riccardi Honders, and Catadioptric optical tubes. Choosing an astrograph depends on how the astro-imager wants to observe, what focal length and focal ratio it has, aperture, optical coatings, and how suitable it is for the camera they intend to use.

A key specification very important to consider when choosing an astrograph is focal ratio in relation to aperture. This is an important to remember because focal ratio determines what the magnification and field of view the observor will get. Therefore, if the observor intends to mainly view deep sky objects with lower surface brightnesses, a shorter focal length will reduce magnification and increase field of view since most deep sky objects tend to appear very large but not bright. Astrograph telescopes with slower focal ratios such as an f/12 will provide higher magnification and smaller field of views; better for planetary observing.

    Officina Stellare - Veloce RH 300 Riccardi-Honders Astrograph OTA

    Officina Stellare is providing excellent care in constructing the rear holding cell of the Veloce 300 astrograph's primary mirror. The 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. The convection and thermal irradiation are greatly improved with the use of three high quality axial fans in the back of the astrograph's cell.

  14. Veloce RH 200 Full Package

    Officina Stellare - Veloce RH 200 Riccardi-Honders Astrograph Full Package

    Officina Stellare has focused on simplifying the collimation between the Veloce astrograph's mirrors to resulting in a stable, efficient but easy to use system. Collimation is achieved on three points (the minimum required points to generate a single plane) that use 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. Officina Stellare has made this one step easier! Finding the correct positions is a snap.
