2 inch 32mm Wide-Field Super-Plossl Telescope Eyepiece NEW XL lenses For Sale
2 inch 32mm Wide-Field Super-Plossl Telescope Eyepiece NEW XL lenses:
This is a very popular focal length / Low-Power eyepiece that I make as a budget eyepiece using the same lenses that are found in eyepieces with the smaller diameter 1.25" barrels. The original eyepieces use the larger diameter lenses, but the manufacturers placed them above the smaller 1.25" barrel because the 1.25" is a more popular size. The smaller 1.25" barrel chokes the afov down so much ( below 40 degrees ) that they simply don't perform as well as using the same lenses in a 2 inch barrel.
This is a NEW version using higher quality XL lenses that make a big difference in performance and appearance. The new lenses have beautiful multi coatings & blackened edges to improve contrast and help eliminate the "ghosting" effect of standard lenses. This *budget 2 inch 32mm W/F Plossl may be the best dollar value out there in a 2 inch eyepiece.
Russell Optics puts them into a 2 inch housing to make this budget 32mm Wide-Field Plossl with 20mmeye relief and is threaded for standard 2 inch filters. The lenses are coated with anti-reflective material to reduce glare and stray light, but at the same time allowing as much light through as possible. This yields a brighter image in smaller telescope ( up to 8 inch diameter ). When the lenses are in the larger housing and 2 inch barrel it opens up the afov drastically to 60 degrees afov making it a much better performer. This is by far the least expensive way to build a low-power, budget-minded 2 inch eyepiece using all new components. These make great star-party eyepieces, and a great gift idea for that budding astronomer on a budget.
*Please note.....on Telescopes with a central obstruction ( Like SCT's, Maksutov's, or Newtonians ) a basic rule of thumb is to keep the magnification above about 35x. Once you go below 35x you stand a chance of losing contrast. If your obstruction is larger than 25% of the primary you could also get a "ghost" image of that secondary mirror.
If you have any questions or concerns I will gladly help you make the correct choice for your particular choice.
