I decided to write an article about the difference between two eyepiecess. My Telescope, was delivered with an eye plossl 20 mm. Then I bought a Super Plossl 7.5 mm. With these two eyes I explored the sky for two years, although I knew the Baader Hyperion eyepieces, the budget does not allowed me to buy one until recently, its price is quite high for this time of crisis. here is a brief presentation of the specs between the two.
Use on: 1.25 "
4 optical system with lenses in two groups
Apparent field of view: 50 degrees -6 Mm eye relief
8 elements in 5 groups
Apparent field of view: 68 drade 20 mm eye relief
So far I have seen only one celestial body with Hyperion eyepiece and 20-mm field of view, I was fascinated. Although I have a short focal length telescope with f / 4.9! with 7.5 mm plossl I struggled to see through it, because its very little eye relief. Astrophotography Not to mention that by plossl 7.5 mm is almost impossible. Hyperion has two threads (M54 and M43) can be mounted on different cameras, some models can be mounted directly, some with various T2 adapter rings.
