Hi
For various reasons, I find a correctly orientated image, (vertically & horizontally) as given by an Amici prism in a diagonal, much easier for me to use with my observing.
I absolutely loved the Baader Amici prism with the ClickLock. The build quality is lovely and it gave really great views - except when you try and use it on an object brighter than about magnitude 1.5, whereupon you see the infamous diffraction spike ruining your view.
I know this is a fairly common issue with prisms and with Baader Amici prisms in particular but I have also heard of people trying several and then finding one without the diffraction spike issue. Mine was bought from a reputable online only astronomy supplier on the USA west coast who assured me they tested the prism prior to my purchase but they obvioulsy did not. They did give me a refund in the end. I would really love to try and obtain another Baader prism but without the diffraction problem.
My question is, have you done the process of trying several prisms before getting a good one? Who did you use? (please feel free to PM me) Did you end going directly to Baader? I would do that ordinarily but I now live in the USA, not Europe. Have you another non Baader correct orientation prism that you could recommend to me ? (Although I have to say once you use a Baader diagonal with a ClickLock there really is no going back to the fiddly adjustment screws!!!)
Thanks for any advice, sharing of experiences or recommendations.

Baader Hyperion Eyepieces
5mm - £70
10mm - £70
24mm - £70
Or all three for £190
I bought these over on ABS a while back, used them a couple of times, and have never touched them again, so selling for future upgrade points.
They seem like perfectly OK eyepieces, but the Baader and TV zooms are perfectly good for my portable viewing, and take up less space and weight.
Price includes UK postage. Payment by bank transfer (preferred) or PayPal (buyer pays fees).

Does anyone who has one of these zoom eyepieces know if there is a t-thread hidden under the twist-up rubber eye-cups like there are on some other zooms?
I don't have a zoom in my set yet and don't want to break the bank. I just aim to use it mainly for visual e.g. being lazy with one 'no faff' eyepiece or when I'm being more dedicated, scoping out the seeing at different magnifications before changing to a dedicated eyepiece.
I'd only use it for occasional photography but would rather buy one with a T-thread.
For reference here are the different branded versions I can find:
OVL Hyperflex version: https://www.firstlightoptics.com/ovl-eyepieces/hyperflex-72mm-215mm-eyepiece.html
Skywatcher Hyperflex version: https://www.365astronomy.com/SkyWatcher-HyperFlex-7E-7.2-21.5mm-High-Performance-Zoom-Eyepiece.html
I had read in the previous thread that the Lunt version of this zoom is also generic but the only one I can find looks quite different and is twice as expensive and has a different field of view so not sure about that?

Thanks for any feedback (or any other recommendations for circa £100 zoom lens that might have a hidden T-thread)!!!
