Yes, Ritchey Chretins are a fantastic choice for deep sky astrophotography! Amateur astronomers also buy telescope optical tubes so they can build a custom telescope system, with an equatorial mount and either a traditional tripod or placed on a pier in their personal observatory. They are also not as good as other telescopes like SCTs for planetary imaging due to their lower contrast as explained above, but you can still absolutely use one for capturing the planets just at reduced contrast." RC telescopes are usually best for imaging because of their lower contrast compared to most other telescope designs. The main mirror comprises 492 smaller hexagonal mirrors - it . You can use a telescope to take pictures of birds, animals, landmarks, people and more during the day. The focal ratio is calculated by dividing the aperture (mm) of the primary mirror or lens into the focal length. So it would be a no-brainer to get the biggest telescope you can afford, right? If you already have an equatorial mount (the one used with optical telescopes) with at least50 kg load capacity and Losmandy dovetail clamp (like an EQ8), thanks to the products developed by Radio2Space, you can turn your telescope into an amateurradio telescope, and start your amateur radio astronomy program without the need to have extensive knowledge of radio techniques. Next up is this 40-inch (1-meter) aperture telescope from Planewave. Other aberrations, such as astigmatism, can be greatly reduced with an additional field flattener. This is a good combination of field of view and magnification for people who want to do a bit of everything the astronomy hobby has to offer. We recommend a computerized equatorial mount to make it easier to align, find and track celestial objects. The Ritchey-Chretien is designed for imaging. A special system of rear tie rods increases the rigidity of the structure while minimizing the deformation of such a large diameter parabolic antenna.

Objects that were in sharp focus at a particular magnification on Saturday night may not come to focus with the same eyepiece on Sunday. An achromatic refractor is designed with two lenses that are therefore only capable of focusing two wavelengths of light, and are usually the most economical. The MPG/ESO 2.2-metre telescope was originally constructed by the Max Planck Institute for Astronomy (Heidelberg, Germany) and intended to be sited in Namibia. The folded light path allows for a short tube assembly even with relatively large apertures of 8" or more.
