Ciao, stranomersi! Today, I want to show you a great observatory class telescope that offers a stellar design to provide a large, correct image circle with an universal f7 foca ratio. This is the Ridicade 400 and we created a bundle with the exacto for inches robotic focus. Ridicade means a Riccardi Darkircam and its an optical system based on a spherical secondary mirror with integrated, corrected group that not only provides a very large, correct image circle but it's easier to collimate in respect to standard richecretian design. In particular, the Ridicade 400 is 400mm in diameter and 2,800mm focal length. The telescope weights 44kg and it has a carbon aluminum, true stube designed to be very stable with temperature changes. In order to bundle with our robotic focusers with design a specific adapter to let you connect a Zato for inches to the M120x1 female thread that you have in the back cell of the Ridicade 400. This allows you to have our high precision and load capacity robotic focusers. Oficina Stellare Ridicade 400 has 294mm back focus from the rear self and since the Zato for inches plus the adapter is 95.5mm thickness you still have 194.5mm space that allows you to use even thick imaging trains composed by many accessories. And if you add the RCO 3 inches camera rotator and field rotator after the Zato for inches, you still have 174mm back focus after the rotator. You can also add the eagle, for example, by connecting to the upper losmandi style of the bar by using the plus clamp. This allows you to remotely control and power all your devices in a very easy way. I really like this Ridicade 400 telescope and the Zato robotic focuser because it provides observatory class performance with a large correct image circle in an easy to climate optical design and a telescope that you can install in a 3 meter diameter dome.
