Product Info

Manufacturer Description

GSO's Super-Plossl eyepieces have been some of our most popular sellers over the years. Users will experience incredible views without breaking the bank or impinging on your telescope's balance. They represent what is perhaps the best buy today for astronomers on a budget or for beginners. But don't be fooled by their low prices - these might well turn out to be all the eyepieces you will ever need!

The GSO Super-Plossls are available in a 1.25" barrel size and 9 different focal lengths ranging from 4mm to 40mm. The 4mm, 6mm and 9mm models are great for high power planetary and lunar observation.  The 12mm and 15mm are perfect intermediate focal lengths, performing well on both deep-sky and planetary subjects.  The 20mm and 25mm models would be excellent choices for low power scanning of open star clusters and viewing larger galaxies. The 32mm and 40mm models offer a wide field and are superb for wide field scanning, detailed observations of large diffuse subjects or as a finder eyepiece.

Features:
- All eyepieces are fully multicoated (FMC) for maximum light transmission
- High quality lenses provide the best-possible sharpness all over the field of view
- Blackened lens edges reduce light scattering and improve contrast
- Fold-down rubber eyecups to keep out stray light
- Barrel features a safety undercut for added security
- Comfortable eye relief at all but the shortest focal lengths (As in all Plossl eyepieces, eye relief can get tight at the shorter focal lengths but this is design constraint, not a fault of these eyepieces)
- Includes two end caps

      Cons:

      Comments:

      My goto for aligning and lower mag viewing. Helps me dial in my scope's goto and gives fantastic views of DSOs and solar system alike. Well worth the money.

      5.0 I will be buying more GSO products.

      Pros:

      Quality Lenses

      Cons:

      Comments:

      I'm using this eyepiece on my 6" reflector telescope. I immediately saw the difference in viewing sharpness of Saturn when compared to my old eyepieces. Nicely made and packaged well. I will be ordering additional GSO Plossl eyepieces.

      4.0 Really good value eyepiece

      Pros:

      Quality Lenses,Strong Construction,Accurate

      Cons:

      Short eye relief

      Comments:

      I needed an eyepiece to fill the gap between my Meade 9mm and Orion 25mm eyepieces. I am on a tight budget and this eyepiece fit the need and cost perfectly.
