Refractor Telescope Optical Tube Assemblies

 
 

If you want many of the benefits of the refractor design without having to clear out your savings account, you may wish to check out the Explore Scientific 127 mm Achromatic Refractor. With excellent optics for such a short focus achromatic doublet, this telescope excels at low to mid power deep sky viewing. Under dark skies, star clusters will show their incredible beauty with pinpoint star images. Large nebulae like M8 “The Lagoon”, and M42 in Orion will show beautiful structure and clarity, making it hard to pull your eyes away from the eyepiece!

If you are looking for a super quality imaging refractor that can be handled with a mid-sized equatorial mount, you may wish to check out Sky-Watcher’s Esprit 100 mm ED APO Triplet. This fine telescope has what it takes to perform like a much more costly OTA. With a three element FPL-53 ED lens and a thread on field flattener designed specifically for this telescope, pinpoint clarity is yours from edge to edge when using your favorite camera.

Aperture for aperture, the unobstructed design of a refractor can often provide better contrast than most obstructed designs like Newtonians and Cassegrains. Also, since lens coatings generally scatter less light than mirror coatings, the background sky is noticeably darker. On top of that, most refractors are extremely well baffled against stray light, therefore your target of interest appears to jump out with clarity and brightness far surpassing what is normally expected with their often modest apertures. All this and much more is yours with a quality refractor from High Point Scientific!
