A zoom eyepiece is really practical: It combines several focal lengths that can be adjusted simply by rotating the body. So, you don’t need a whole eyepiece set, and don’t have to switch them out if you want to increase magnification. Unfortunately, zoom eyepieces do not attain the edge sharpness and field of vision of a fixed focal length lens.
With the Hyperion Universal Mark IV zoom eyepiece by Baader Planetarium it’s a different matter! This tried and tested zoom eyepiece has been improved even further, and offers, for magnification factors with 24 to 8 mm focal lengths, a very good image and at the greatest magnification factor, a field of view of 68°. Unlike other zoom eyepieces, the field of view is not narrowed at greater magnification!
You can now purchase the Hyperion Universal Mark IV for just 220 euros. You save € 25 on the recommended retail price!
In the set with the 2.25x Barlow lens you can now even save 27 euros!
The word universal in the name of the Hyperion Universal Mark IV aims to offer almost unlimited uses: Use the zoom eyepiece visually with a long focal length Dobson telescope to view the planets and planetary nebulae, or with a Bino viewer or with a spotting scope for bird and nature watching.
This zoom eyepiece is also very good for a-focal photography:
Many adapters are available for the wide range of uses of the Hyperion Universal Mark IV.
