Refractor. I personally wouldn't recommend Newts for imaging for new comers, stick with a nice refractor, learn the trade, then move up to a newt and the leasons learnt will help you massively. . Astro-imaging is a great way to share your views of the sky with friends and family. c) Newtonian reflecting telescope d) Cassegrain reflecting telescope (detailed ray diagrams not required) There are two types of telescope that we will study: refractor and reflector. SCT vs Newtonian for CCD imaging. A convex lens is used at the end of a tube to bring an image into focus at a point. Is there a rule of thumb at which apertures a reflector starts to outperform a refractor? SCT vs a high-end refractor. Believe it or not, I can tell you that the most intrinsically perfect system for astronomical work is a Newtonian reflector. Many seem to think there's a certain magic to certain types of systems, something special about a Maksutov, or a Cassegrain, or a refractor, or some other exotic system. A review of three Astro-Tech astrographs (the AT6RC and AT8RC Ritchey-Chrétiens, as well as this AT8IN Imaging Newtonian) in the December 2009 issue of Sky & Telescope said "While all three of the Astro-Tech scopes represent excellent value, the AT8IN, with its 8-inch aperture and $499 price tag, wins the biggest-bang-for-the-buck award . These scopes were born to do astrophotography with pinpoint stars across the field and coma-free sharp image. For example would an 81mm refractor do better than an 8" SCT or Newtonian for either observing or imaging? 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. I think those who dab in refractor work have a bit better time with dual scope imaging which you can stack data from different scopes and not have to worry about diffraction spikes from say a newtonian, refractors are just easier to match up with each other for this purpose. Whether you are new to astro-imaging, or a seasoned expert, we have you covered. Something other than a Newtonian. My 2 pennies to the fract vs Newt war . With an astrograph telescope, you can easily look back at your favorite celestial objects and enjoy views of the sky anytime you want. Takahashi FSQ-85ED Altair Astro provide the Starwave 70 ED, f/5, (so 350mm focal length) Quad APO Imaging Refractor which is equipped with a rack and pinion focuser and has an image circle of 42 mm An optional focal reducer gives a focal length of 328mm, a focal ratio of f/3.9 and a 40mm imaging circle. Edited February 20, 2011 by Catanonia 10. . 200 mm SCT vs 130 mm refractor? 11. 12. Refractor vs. SCT Comparo, sort of. I would in particular like to compare the William Optics GT81 and the Celestron EdgeHD 8" Will the Celestron do worse?
