Newtonian astrograph vs refractor


Borg's Refractor Astrographic Systems Differing design principals for visual vs. While not the first to consider melding the best attributes of refracting and reflecting telescopes into a single instrument, Dmitri Maksutov did conceive an optical system that was to spawn a class of very compact, high-definition instruments that would be relatively easy to manufacture. Both are Granted, refractor telescopes sometimes suffer from chromatic aberration. Starwave 152 V2 Red Tube f/5. Newtonian telescopes, which are popular for star gazing, are usually unsuitable for a spyglass, since the eyepiece is on the side of the scope. . In the Maksutov-Newtonian, the meniscus is closer to the spherical primary, commonly inside its focal point. The TeleVue TV-60 60mm f/6 APO (Doublet) Refractor OTA is an excellent choice for the astronomer on the move who demands a high quality compact system. This usually manifests itself as a purple or green fringe around the objects. designs compared to with refractors, and a reflecting telescope also typically  Apr 28, 2019 In fact you can get a very good Newtonian astrograph if you are willing to spend But you also list of number of refractors, say you don't like collimating. Although many observers would say that the very best images come from apochromatic refractors, this may only be true up to 5” or 6” beyond which size, the sheer complexity and cost of producing the many accurate surfaces from completely distortion free glass conflicts with the desire for greater aperture and a more compact design. When I got into imaging in the early 2000’s I converted the old telescope into an astrograph and it worked pretty well but there are limitations. As you say reflectors do offer greater aperture than comparably priced reflector telescopes, but they suffer from things that refractors don't. Stellarvue refractor telescope with solar filter, set up by the National Capital Astronomers, at the Rock Creek Park Nature Center in Washington, DC. Only 4 stars because the focuser leaves a bit to be desired but still for this money you can buy a Moonlite for it and have an excellent f/4 astrograph.

This is the oldest style of telescope and has many advantages. I think that eventually I want to do some astrophotography, and I have read that a Schmidt-Cassegrain is better for this, but they are more expensive. I love analogies and my analogy for seeing vs transparency is to use a swimming pool. There are many reasons why the refractor group is big, but the Maksutov Newtonian is the most refractor-like of non-refractor telescopes if you know what I mean.

The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used for long focus camera lenses. At the end of year 2012 I have sold my Losmandy G-11 mount because I knew that one day I will have to adopt a Newtonian system as my primary astrograph (and I did not want to overweight the perfectly working G-11 and I did not want to keep two „big“ mounts as I am using only one at a time). bear in mind the 500 rule, divide your focal lenght by 500 to find out the longest exp time you can use before trailing shows. The focal lengths of both instruments are very comparable; 1200mm for the Newtonian and 1280mm for the refractor. Like any other telescope, their primary function is to gather as much light as possible, rendering distant objects brighter and easier to see when magnified. Astrographs, as they are commonly referred to, often have fast focal ratios which make them very efficient at gathering light and large image circles that have been corrected for optical aberrations.
