TS Optics SuperView 30mm 2" eyepiece with built-in M57 thread
Eyepiece for visual observing as well as for digiscopy. With integrated M57 thread and adjustable eye relief
The SuperView eyepieces are particularly well
suited for projection photography with compact digital cameras. At the
same time they also perform very well for visual observing.
Applications
-
Visual observing: The 2" Superviews are excellent wide angle ERFLE eyepieces
-
Digiscopy: Both nature and astro imaging: projection photography with compact digital cameras with integrated objective.
Advantages and Features-
Eye relief can be individually adjusted for best possible observing comfort. The rubber eyeguard can be extended. You can easily see the entire field of view with or without eyeglasses.
-
The 2" Superviews are wide angle eyepieces with a large apparent field of view.
-
With their excellent multicoating, blackened lens edges and intentionally overdimensioned lenses the SuperViews offer superb contrast and an image free of internal reflections.
-
The SuperView has an integrated M57 thread. From there it is easy to attach most cameras. The M57 thread can be moved up and down on the eyepiece until you reach the optimum distance between the eyepiece and the camera.
-
Much larger illuminated field: One of the biggest problems for digiscopy is field
illumination. The problem is particularly critical on cameras with a
large lens diameter (bridge cameras). With the SuperViews you can keep
the minimum possible distance between the camera and the eyepiece. This,
coupled with the large diameter of the exit lens of the eyepiece,
maximizes the illuminated field.
-
The threaded connection between eyepiece and camera is very safe and also automatically centers the camera behind the eyepiece.
- Newtonian telescopes often have the problem that back
focus is not sufficient for DSLR cameras. With the SuperView you can
avoid that problem. The eyepiece will move the focus position further
out so that you can reach focus with your camera.
Optimizing the Distance
For digiscopy it is important to keep the minimum possible distance between the camera and the eyepiece. The eyepiece's thread can be moved up and down on the eyepiece so that you can reach precisely the best distance.
At the same time this allows you to adjust the position of the eyeguard for visual observing.
Once you have found the best setting you can lock it in place with a thumbscrew.
