It went into operation in 1970, and its early successes showed the excellent image quality and observing conditions at the top of Mauna Kea. From my research, many 1M telescopes are $250,000+. However, when it comes to your own equipment, if you want or need to keep your glasses on, we recommend all of your eyepieces have a minimum of 15 mm of eye relief, 18-20 mm is even better. While there are still equatorial mounts on the market that have motors available for both axes (a minimum requirement for astrophotography), computerized mounts are more plentiful than ever and can be an economical choice since you won't have to worry about adding motorization to your manual mount later on. It is common to find fast imaging Newtonian reflectors for sale as optical tube assemblies only, allowing the astro-imager to use his choice of equatorial mount. } A special system of rear tie rods increases the rigidity of the structure while minimizing the deformation of such a large diameter parabolic antenna.

The2.2 meterinside diameter provides plenty of space to operate up to a 14 Schmidt Cass or a refractor 1400mm long. As an example, the Planewave 700 is $210k and already blows the budget - but the 600 is only $75k. . The optical system utilizes a Nasmyth focus through both. Schmidt-Cassegrain telescopes use a folded light path design to keep the tube assembly portable for their aperture. RC telescopes use hyperbolic mirrors to eliminate optical errors like coma and chromatic aberrations off-axis while producing the flattest focal plane possible without lenses. The standard Schmidt-Cassegrain Telescope, or SCT, has a medium focal ratio of f/10, making it a jack-of-all-trades; good for terrestrial viewing, enjoying the planets, deep-sky observing, or astrophotography. Astro-Physics introduced the redesigned Stowaway at the Northeast Astro-Imaging Conference on April, Our new 254 mm f/14.5 Maksutov-Cassegrain generated a lot of excitement when we introduced the proto, Astro-Physics introduced the re-imagined "Gran Turismo" at the Northeast Astronomy Forum (NEAF) on A. Astro-Physics sends periodic emails to announce new products, software updates and notices. ", Without counterweights the radio telescope would be completely biased towards the front (because of the weight of the primary reflector and LNA + feedhorn group with support rods) and therefore could not properly point and track objects in the sky. There are also focal reducers available to shorten a longer focal length and create a wider field that is better for astro-imaging, especially with today's larger sensors. These can work well for casual viewing and will allow you to see the planets of the solar system, other objects in the night sky, and but deep-sky objects like galaxies and nebulae may .
