    Default Baader Hyperion 17mm Eyepiece



    I was at the local scope store today looking to get a polar scope. However it was not in stock so I ended up looking at some eyepieces. I ended up purchasing a 17mm Baader Hyperion Modular Eyepiece. Luckily I headed straight up to my dark sky site in Thornbury, Ont. I managed to get it out for a while and all I gotta say is WOW!! The 68 degree field of view made Jupiter & M45 jump right out on me much clearer than any of my other previous eyepieces. I'm going to be heading out again in a few hours to check some more things out. But I have decided I am going to buy the entire Hyperion line because even though I only used this eyepiece for maybe a half an hour the views were simply amazing. Any the fact I can switch between 1.25" & 2" on the same eyepiece is an extra bonus. The $151.00 I spent on this eyepiece is well worth it!

    Major difference. The eye relief was so much better than any other previous eyepiece I have used. Stars were sharp right to the end of the field of view. I fell in love with this eyepiece the minute I looked through it.

    Keep your eye out for used Hyperions or Used Orion Stratus (same thing) ....

    I own a few Pentax XW's and a Few Panoptics that I use in my F/10 Scts and the 2 Orion Stratus (13 & 17) in my case more then hold thier own ..(and this is not even considering the price differential)...

    Good eyepieces ..GREAT Prices...

    I have a few of the Hyperions including the 17mm. The 13mm and 17mm are my favorites. I've been able to pick mine up for around $80-85 used in the US. Good performance for the price.

    Agree, Hyperions are great; but before you buy the entire line, you might want to consider trying the Hyperion 8-24mm zoom first - have come across forum posts saying if they had known about the zoom earlier, they'd have gotten it instead of the 8mm/13mm/17mm's. Just 2 cents.

    Best,

    I am thinking of getting the hyperion zoom as well in addition to the fixed focal length eyepiece set. Mainly I want to get the fixed focal length set for the added feature of being able to eyepiece projection imaging right from the eyepiece. I am going to be seriously getting into astrophotography in the new year and will be upgrading to a bigger scope (10" LX200 ACF) which I have already started making payments on, and these eyepieces from the reviews I have read will compliment my new scope nicely. That and I am one of those strange people that if I buy a few things from a set, I have to complete the whole set. It's made my wallet cry in the past.

    I can afford to buy two hyperion eps or one Nagler 13T6. What would you folks recommend?

    I'll vote for the Nagler for reasons previously outlined. Cue the Hyperion crowd......

    It depends on how much importance you give to a wider field of view and tolerance for some softness at the edge if you have a fast scope to use the eyepieces with. Hyperions have a published AFOV of 68-deg while the Naglers come in at 82-deg. There are adherents to the 68-70 deg EPs because it gives an eye-full view without the necessity to move the eyes/head around to be able to see the entire FOV as is the case with the Nagler where you have to move your eyes around to see the edge of the field. (There are exceptions where some are able to see the entire 82-deg field in one setting.) Then there's the speed of the scope to be used - if you have a fast f/4 or f/5 scope and want sharp to the edge views then the Nagler is the way to go. On the other hand if you have a slow scope like an f/10 SCT, the Hyperion will do very well with it. On my f/10 C8 scope, I do not see much difference between a Nagler 12mm and the Hyperion (zoom set at 12mm) which are both tack sharp to the edge, it's just that the Nagler has a bigger AFOV. Also for the price of two Hyperions, I'd get a Hyperion 8-24mm zoom instead. Just 2 cents.

    Best,

    Hernando
