Baader Hyperion on Dob?

[Swedeman2013]

Hi, has anyone had success with Hyperions of 5 or 8mm on Skywatcher200's as I'm looking to upgrade from stock e.p's for planetary viewing ( and lunar). I hear they are great and not too expensive?

[YKSE]

It may not suit your scope I'm afraid, even though they are best eyepieces in Erfile design. your scope is f6, on the faster side for these eyepices. You can follow John's comments in this thread

Yes I have a Hyperion 8mm with a 200P at F5 and they are a little soft. They are ok I guess but im sure there are better in the price range.

I've had good results with the 5mm Celestron X-Cel LX, which is a cheap approximation to the Hyperion. My 24mm and 10mm Hyperions are also great with it as well. The XCels do have the benefit of being more dainty in size compared to the Hyperion hand-grenades!

I've owned both and I'd say that the X-Cel LX's are a bit better than the Hyperions. Not "cheap approximations" to my mind

I use the 5mm, 8mm, 13mm, 17mm, 21mm, 24mm Hyperions and 31mm Hyperion Aspheric in my 200P dob. They look good to my eyes on a variety of targets from lunar to planetary to DSOs.

The hyperions really do seem to split opinions, is there any chance you could get to try one out before you buy? in my 6" f8 the 21mm Hyp' is a lovely EP, but in the 10" f4.8 its absolutely awful. At f5 I imagine it would suffer a fair bit too. Having said that, the 8mm will perform much better than the 21mm in this respect. My advice (I've said it before and I'll say it again) is to look out for a S/H Radian... you should be able to pick one up for around £100 and will blow the Hyperion out of the water in a faster scope.

[Moonshane]

I agree about the Radians. also watch out for a used type 2 nagler. I got a 16mm for just over £100 and in some ways I prefer it to my 13mm Ethos. also in my humble opinion, you cannot go wrong with televue plossls. a 15mm and 2x barlow is a great match for your scope, giving mag of 160x which will work a lot of the time and be your best higher power quite often.

[Qualia]

I never got on with the 5mm Hyperion. Neither in my 10" Newt (250x) or 4" frac (200x). To be honest, I never have much cause to go for those kind of magnifications but when doing so prefer the sheer quality and 'concentrated tightness' of a Baader Genuine Ortho. If you were looking for a better quality, similar field of view and priced EP, I agree with both George and John and suggest that the X-Cel LX will be the better purchase. I found that it outperformed the Hyperion not only optically but also as a lighter weight, easier to manage eyepiece.

Other than that, one cannot go wrong with Andy's and Shane's advice: so long as it is in good condition, you simply can't go wrong with purchasing a Tele Vue secondhand. Each type will no doubt surrender up delicious views and long moments of pleasure. I think it is worth saving just that little extra (if necessary), knowing that once bought you pretty much have a lifer on your hands.

I use the 10 and 21 mm Hyperions in both a 200 and 250 Dob , with super widefield results.

Where else would you use them, doorstops ?

[twotter]

One thing I did forget to mention is the advantage that Hyperions have over all other fixed focal length eyepieces....fine tuning rings. Their modular design means I can unscrew the eyepiece, fit a 14mm / 28mm / or both fine tuning rings, to tweak the focal length and get the maximum magnification for any given nights viewing conditions. As far as I know the only eyepieces that are as flexible as that are zooms, and they come with their own pros and cons. I use the fine tuning rings far more often than I thought I would and I know I have had nights observing when they have turned an 'okay' night into a 'brilliant' night.

I still have my collection of plossls and use them from time to time in both my telescopes, but I find the 68 degree field of view of the Hyperions to be more comfortable and appealing to use. Looking through a plossls 52 degree field of view feels constricted and I can only imagine looking through an ortho would feel positively claustrophobic....though I do intend to find out for myself one day

I've bought a few of my Hyperions new, but most are 'pre-loved' and cost from £65. Weighing up their pros and cons I consider them to be a good buy for both my telescopes.

[bingevader]

Eye relief will be the other thing to consider with a plossl at those focal lengths, if it is something that bothers you or you wear glasses.

I'm still waiting to use my 5mm X-Cel LX so can't comment on that yet other than to say it's a solid, well build piece of kit.

Cheers

Looking at the responses to this thread, thats clearly the case

[Swedeman2013]

Thanks twotter, your feedback is really helping right now, I appreciate it

[swamp thing]

I would second (or is it third ) the radian option. These are great eyepieces in faster scopes.
