View Full Version here: : Orion Stratus EPs' worth checking out

I have finally taken delivery of my latest eyepiece....a 17mm Orion Stratus with a 68 degree FOV. Bintel kindly agreed to import from the US for me for AUD179.

It is a beautiful looking EP :love: , as large as a 22 Panoptic, with the top glass of the EP having about the same diametre as a 30mm GSO superview. It comes in a leather pouch (most certainly not wallaby).

As for performance, I took it out for a stroll last night before Luna awoke, we did a tour of the usual suspects: Tarantula Neb, Saturn, M43/43, some Puppis OC's, 47 Tuc, etc.

My initial observations:

1. Very easy with eye relief.....no blackout / kidney beaning whatsoever. Would definitely suit persons bespeckled.
2. Lovely contrasty images, performs very well on open clusters and globs, with good sharp stars and dark skies.
3. Some mild degradation of image at edges, but nothing that really compromises the main FOV.
4. Performed beautifully on Saturn, with no obvious degradation in quality of image compared with 22 Panoptic.
5. Did well splitting some close doubles (not sure of names of the doubles...I was scanning the skies without GOTO).
6. It has both 1.25 and 2 inch settings at bottom (also like the 22 Pan). The 2 inch setting is unfortunately short, and I was initially a little concerned until I built up some confidence that it wasn't going to drop out of the diagonal!
7. In my 2500mm focal length SCT it provided a very comfortable 147x magnification, which means it will give me lots of use in the future as a solid mid-magnification EP.

Overall comments? I am very happy, I think it will have a long life in my collection of EP's. I might look to get the 13mm in due course if I continue to enjoy its performance.

I understand that Bintel actually imported three of them, so there are two more available for those who are quick! Bintel is considering bringing in the range of Stratus' as a less expensive option to the Televue range. I think that would be a very good move on their part, especially for those of us with slower scopes who struggle to see too much difference between EPs' in the$300 to $600 range! :whistle:

Thanks for the report, Rod. The Stratus are impressive EPs indeed, especially considering the price. My 13mm is as capable as a 13mm T6 Nagler on-axis, and I spend many hours comparing those two. Edge performance is also very good in my f6. Just the very last couple of degrees suffer severely but like you said it is nothing distracting. Maybe it is because the original (Vixen LVW) was a 65 deg but the Strats are field stopped to 68.

Bintel should import them, and keep the markup minimal. These EPs do fill a huge gap in the market, with super-wide FOV that works well even in fast scopes. You can already get the very similar Baader Hyperions in Australia but the markup is so high, you'd be better off buying overseas. Go Bintel! (Bintel Melbourne are not very impressed with the Stratus though. :shrug: )

I've got the Baader Hyperion 13mm, would be interesting to compare with yours Steve. I suspect that it's exactly the same EP as the Stratus despite claims that the EP is different. In my LX 90 (2000mm f/l) eye placement is sensitive, in the wrong place and you get blackout and kidney beaning. I've found that with the rubber eyecup folded up the eye falls naturally to the correct position. My experience with the 13mm is the same as Rod's, excellent contrast, noticeably more detail than my 14mm S5000 Meade Plossl and sharp almost to the edges. Image scale seems larger than the 1mm difference in f/l would indicate as well on the Baader. It's difficult for me to make a subjective judgement as I have no access to Panoptics and Naglers which seem to be the benchmark, but I am quite impressed with the 13mm. :D

Rod,

I am glad you like it. I reckon if this was a throwback after having to sell the 13mm Nagler T6, you wouda been chasing me for retribution :)

BTW I was talking to Don Whiteman about your eyepiece yesterday and he mentioned that Bintel wanted us to review it for them and post the results on IIS forum. He asked what we had to compare it agianst and I mentioned my 14mm Pentax XW and Andrews 16mm Nagler T2.

Does anyone thats coming to Kulnurra have anything else to compare the 17mm Stratus against such as:-

16mm nagler T5
17mm Vixen LVW
18mm TV Radian

15mm GSO Superview

John,
I can't make the 25th...I've got to do a fair amount of traveling in the next few weeks...but, I can "loan" my 16 mm T5 for comparison if it is helpful...I'm not too keen on mailing it but, we could probably meet this week sometime if you are interested in its use...I'm pretty stacked with actual work stuff this week so let me know what day might work best and a range of times...You are at the Gordon Club right? If so, I'm just on the other side of the train station up nearer the Pacific Highway so it should be relatively easy to get together...

Scott,

Yes I am at the Gordon Club, that offer is very much appreciated. Send me a PM when you get a chance with your contact numbers and I will give you a call and arrange a time to meet.

doesnt sound like a fair comparison tho.

David,

Whilst its not a fair comparison comparing the $180 17mm Stratus with the $60 15mm Superview, its likewise not a fair comparison comparing the 17mm Stratus with the $400 plus 14mm Pentax XW or either of the 16mm Naglers.

What we want to establish is, "what do you get for your $180" and where does the eyepiece sit quality wise in the whole scheme of things.

fair enough. if someone wants to take it up there they can either pick it up from me at work in rockdale or from home.... just return it in one piece ASAP :)

Ving,

I have confidence that ausastronomer (and others) can take care of your baby if it works out that they use it...

He just picked up my 16 mm T5 and I was pleased to see him carry it two handed out the door...of course maybe he tripped once out of my site...but he did handle it nicely while I watched him go (misty eyed)...
