Explore Ultra-Wide Eyepieces - Comfort, Quality, Value. Explore Scientific 82° Series eyepieces, with their 82° apparent field of view, immerses you in a very comfortable ultra-wide field that naturally promotes relaxation at the eyepiece. When you relax your eyes and take in the scene presented before you, it is much easier to observe for longer periods of time, and details begin to materialize that may not have become apparent to you at first glance. Another great benefit of ultra-wide eyepieces is the ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.
Protection from the Outdoors - By making the eyepiece body Argon-purged, the waterproof eyepiece internal elements will remain as pristine as the day they were assembled.
Argon atoms are larger than that of Nitrogen and therefore they are less likely to leak or diffuse their way through the seals over the life of the eyepiece. The atomic radius of Argon is larger than Nitrogen by 0.13 angstroms and has a larger atomic volume by 11.2 cubic centimeters/molecule. Argon also has superior inertness vs Nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse reactions with eyepiece components and therefore extends the longevity of the internal components, and also prevents chemical reactions with other elemental contaminants that may be introduced through a weakened seal. And, finally because Argon is less conductive of heat than Nitrogen, Argon cools slower thereby buffering the effects of rapid temperature changes of the optics.
The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Our waterproof eyepiece is easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements. To insure a perfect seal we test every eyepiece in one meter of water for 30 minutes.
This kit includes an 82° 6.7mm, 82° 11mm, 82° 18mm and 82° 30mm Argon-Purged Waterproof Eyepieces and a soft sided case. These eyepieces are individually boxed in our Will Tirion ?famous? star map box along with the soft-sided case inside an outer box.

PRISM software - the benefit of the full integration
I'm commission a site for serius observations and there are a lot of requirements and technologies to be harmonized and so many areas of post-processing that require dedicated software that you can really get lost. PRISM is open and allows full integration of any equipment in few mouse clicks with an impressive set of analysis and post-processing and automation tools that can drive efficiently you into a professional experience of the sky wonders.
Software is very well thought of and is packed with anything you would ever need.
The interface is gorgeous, it integrates well all the features.
Price is very convinient; I am very glad that Hyperion does not require a subscription fee, like others unfortunately do.
I don't give a 5 star because the pointing model for Alt/Az mounts is unavailble.
