Modern Telescopes, India's largest telescope store is the authorized distributor of baader planetarium. These prime eye pieces provides the best view of plannet and deep sky objects.
 
Eyepiece set with all seven Hyperion focal lengths (5, 8, 10, 13, 17, 21, 24 mm), incl. Eyepiece case
Huge 68 degree wide angle field, tailored to the maximum Visual angle of the human eye
Phantom group coatings in Zeiss class for complete freedom of reflections and maximum image contrast
Modular design of the eyepiece body allows modification of the eyepiece focal length with optional finetuning rings
Camera ready! Almost all DSLR camera bodies can be connected but also simpler fixed lens cameras directly to the Hyperion eyepieces
 
Make the most from your telescope!
 
Most telescopes are supplied with one or two simple eyepieces in the set, which do not exploit the performance of the optics. Moderate contrast and sharpness and small field of vision quickly spoil the fun of the sky observation. With Hyperion eyepieces you get everything out of your telescope!
 
They are suitable for photo! Keep your Astro eyepiece impressions forever by connecting the cameras and camcorders at the Hyperion!
You can distinguish between the series with "Prime lenses" f = 5 mm, 8 mm, 10 mm, 13 mm, 17 mm, 21 mm, 24 mm, the two great eyepieces aspheric 31 mm and 36 mm, as well as the Hyperion zoom eyepiece with infinitely variable focal length of 8 mm to 24 mm.
 
Focal length variability and filter insert
A variety of additional Hyperion focal lengths can be obtained by using our 2" fine tuning extensions rings 14mm and 28mm, or even with our 2" eyepiece filter set. Thus an eyepiece of 5mm focal length can be converted into one of 2.6mm focal length - without loss of sharpness - above all, because no additional lenses are introduced into the bean, which is unavoidable when using a Barlow lens. Also you can of course astronomical 1¼" eyepiece filters in the 1¼" screwing the eyepiece barrel.
 
Further focal modification there are tweaking our rings (FTR) with 14 - and 28mm length. The different possible focal lengths when removing the first lens group, and in combination with filters and fine tuning rings can be found in the table above.
 
Baader Phantom Coating® Group
Baader Phantom Group Coating is a 7-layer broadband coating with extremely low residual reflection. The term "Group" indicates that for each type of glass of the lenses, which come into the Hyperion eyepieces to apply, each effective anti-reflection layer system was expected.
All these various anti-reflection coatings on each glass surface were then optimized so that they are most effective where the human eye has its highest sensitivity at night - at about 520 nm - in the green region of the spectrum.
The best anti-reflection appears almost colourless: this proves that the anti-reflective coating over the entire visible spectrum is equally good effect. Phantom Group anti-reflection coatings are - depending on the type of glass - almost entirely colourless. In this way it is ensured that the least amount of light for a night-adapted eye is lost without any stray light.
If a multi-coated lens (eyepiece or lens) with direct view from the front shows a strong green reflex, then it is not phantom group to a Baader anti-reflective coating! The intensive green reflex is a sign of a little sophisticated coating technique and means that in the spectral range between 500-550 nm the most light is reflected, i.e. is lost.
