    Default Orion EP Opinions



    I'd like to get some opinions about Orion's Eyepieces. Now, I only own 2 EPs, both Orion (which came with the scope). I have the 25 and 9 mm Plossl. I must also admit that I have never looked through any other EPs. I've spent a lot of time with these, and I'm getting to the point where I feel the need to add another to my belt. Naturally I don't want to spend a whole lot, and I'm not willing to spend the money for a Tele Vue. I get the impression that in general, the Orion branded EPs aren't bad (subjective, I know). Since I have a dob I was considering a wider field EP, and was eying the Orion Stratus line. So, what say you guys?

    What F/L eyepiece, Mike?

    I had a look at that line of eyepieces. The 20mm eye relief grabbed me right away. It occurs to me that for the price of 2 you could get yourself a 8-24 Baader Hyperion click-stop zoom. Zoom eyepiece design has come a long way in the last few years, probably fueled by the advances in optical mechanics in point-and-shoot cameras, and the increasing ability to manufacture ever smaller and smaller precise mechanisms.

    Hi Mike. I read somewhere that the Hyperion and Stratus eyepieces are very similar as far as FOV and eye relief. The 13mm Hyperion has become my favorite eyepiece based on my 1000mm F/L and seeing conditions. I don't use the 8mm very often. I'm thinking you'll get similar performance with the Stratus eyepieces. I was able to acquire my eyepieces used in the $80-85 range so I'm pretty happy with price and performance. If the weather ever clears you are welcome to pop over and try the Hyperions in your scope. Provided it ever stops snowing. Man I've got a 600 foot drivway with about two feet of snow right now. Might have to wait for Spring.

    I own 2 Orion Stratus (13 and 17)...and I also own 10 and 20 mm Pentax XW's along with a 35 mm TV Panoptic...

    In my f/10 scts the CHEAP Stratus work very very well even compared to the XW's...and to be honest threy work pretty darn good in my f/6 refractor...

    The Hyperion Eyepieces are a few bucks CHEAPER the the Orion Stratus....I purchased my Stratus on sale ..otherwise I would have went with the Hyperion's...

    I did try them in my buddies Orion 10 inch Dob...and they seemed to work fine in that too...but I did not use them long enough to really tell if they were good, very good, very very good,, etc... They were completely acceptable for a quick look however...

    I would like to second Pierre's suggestion about the Baader Hyperion Zoom. I've only had mine a couple of weeks and actually had it out like 3 times because of the ridiculously cloudy skies, but the views were outstanding and the convenience is hard to beat. I can't imagine you would be disappointed by it.

    Hey Mike, I'll throw my 2 bits in here also. I have an Orion XT8. It is a good scope. I had only a 10mm and a 25 mm to go with it. My first purchase was a 2x barlow. That gave me 4 lenses and the 2 I used most (25 and 25+2X barlow) both had good eye relief. I wear glasses and like the eye relief. I didn't notice if you had a barlow. I don't remember your exact focal length, but I think that with the barlow you will have magnifications something like 48X, 96X, 133X, 267X. After that, my next purchase would be a 2" wide angle lens, perhaps something in the 35 mm range. Then, I don't know where I would go, perhaps something in the 17mm range? With the barlow it gives good magnification and good eye relief. I gave my 17mm to my son and then couldn't get it back from him. I miss that EP. I use my 6.3 mm EP sometimes, but not often. The atmosphere won't allow it.

    I've had good luck with the expanse ep on my XT8 but I somehow got to picking up Naglers along the way after I got the expanse set. I still am using the expanse eyepieces as thier focal lengths fit into my set up very well. No complaints at all.
