BST StarGuider 60º 25mm ED Eyepiece
I have had this eyepiece since December 2020 to replace the stock Eye Piece that came with my Skywatcher Dob Telescope
Features
- Two ED glass elements minimise chromatic aberration.
- All air-to-glass surfaces are fully multicoated for high contrast, high light transmission and minimal ghosting.
- Blackened lens edges reduce internal reflections and further increase contrast.
- Six-element / four-group design minimises field curvature for a nice flat field.
- 16mm eye relief (suitable for spectacle wearers).
- Large 21mm eye-lens diameter for comfortable observing.
- Convenient screw-out eye cups.
- Tactile rubber grip for easy handling in the dark.
- 1.25“ nosepiece with milled safety undercut.
- Accepts 1.25“ astronomy filters.
- Suitable for use with telescope focal-ratios f/5 and above.
Celestron Luminos 2.5x 2" Barlow
I bought this in December 2020 to be used with both Scopes.
Celestron's top-of-the-range barlow lens.
The Celestron Luminos Barlow inserts between the eyepiece and eyepiece holder on the telescope and increases the magnification by 2.5x.
Premium quality 4-element fully multicoated lens assembly delivers superb field flatness and minimal chromatic aberration.
Will accept both 1.25” and 2” eyepieces but the barlow itself has a 2" nosepiece so requires a 2" diagonal or focuser.
Features
- 4-element fully multicoated barlow
- 2.5x magnification
- Can be used with 1.25” and 2” eyepieces
- Brass compression rings securely hold eyepieces without marring the eyepiece barrel’s finish
- Threaded to accept 2” eyepiece filters
- Rubber grip for easy handling in cold weather or with gloves
- Large set screw knobs
