Assignment: Telescope Comparison Students will research three different telescope companies online and then complete the table below for each telescope selected. Research one less expensive telescope (less than $750), one more expensive telescope (more than $1,000), and a different third telescope of your choosing (not a repeat of previous two). See Module 5, Telescopes & Observing , for details on telescope design. Telescope #1: Less than $750 Company Celestron Website https://www.celestron.com Telescope model (Name and catalog number) Omni XLT 150 telescope #31057 Total weight of telescope 12 lbs Price $699.95 Aperture diameter (in inches or millimeters) 150mm Optical design (refractor, reflector, compound) Newtonian Reflector Manufacturer’s description (product summary) Omni XLT series features the stable platform of the CG-4 mount and high quality optics. Using aspheric shaping technology in conjunction with hand- figuring the optics, the Omni XLT presents an image with virtually no spherical aberration. We also added our famous StarBright XLT coating system to further enhance light transmission. What does the telescope include? Eyepieces Finder scope Mount Mount, tripod, eyepieces
Other accessories Would you buy this telescope? Why or why not? Yes, I would by this telescope. Because it is inexpensive and yet still good quality. Based on the reviews, it has a rating of 4.5.
Telescope #2: More than $1,000 Company Explore scientific Website https://explorescientificusa.com/collections/telescopes/ products/ed102-essential-series-air-spaced-triplet-refractor- telescope Telescope model (Name and catalog number) ED102 Essential Series Air-Spaced Triplet APO Refractor Telescope - ES-ED10207-02. Item Number: ES-ED10207-02 Total weight of telescope 12lb Price $1,199.99 Aperture diameter (in inches or millimeters) 119mm Optical design (refractor, reflector, compound) Apochromat refractor Manufacturer’s description (product summary) The Explore Scientific ED102 Essential Series Air-Spaced Triplet APO Refractor Telescope is a true apochromat refractor that reveals our Moon’s stark chiseled craters, Jupiter’s orderly cloud belts and the blue-white stars of the Orion Nebula popping against the complex misty cloud they call home. The ED102 Essential Series Apochromatic Refractor will open up a treasure trove of night sky treats, and provide a solid optical platform to begin serious deep sky astrophotography. A nice compromise between portability and aperture, this versatile high-end telescope offers true diffraction-limited optics and has an objective lens size that performs well in lunar, planetary and deep sky viewing situations. Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine HOYA FCD1 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings.
