Edmund RKE 28mm on Mark V experience
      #5729894 - 03/13/13 09:06 AM

I have tested RKEs 28mm vs 32mm GSO plossls, and ES 24mm 68deg, and all I can said is: I liked RKEs SOOOOO much, that I sold ES 24mm 68deg, and keep only RKEs 28mm!

They look beautiful! What objects were you observing with your MkV and RKE's? I've read a lot of good reports about them. How are the coatings and light transmission of these RKE's? In your attached photo, I do see a lot of bright reflections off of the eye lenses of the RKE's. Is this good? The reflections are the amount of light that's not getting through the eyepieces to your eyes.

Yes, they are beautifull combination with MkV bino!

I have tested them on Orion nebula, some star clusters, Jupiter and stars that are on limiting visuality, and compare RKEs with GSO Plossl 32mm and Explore Scientific 24mm 68deg!

RKEs 28mm produce definetly brighter image af all mentioned above, showe more stars, and wonderful FLOATING effect, and I feel I can touch stars with my finger, like someone have projected stars in front of my eyes in real 3D, definetly experience unique!

On Jupiter, perfect image with RKEs with no internal reflections which I can see when I use Plossl 32mm.

ES 24mm have large FOV, but, view is NOT interesting like in RKEs 28mm, and image is darker (bigger magnification), but anyway, RKEs show little more stars, and much lighter than ES, and did I mentioned wonderfull and unique FLOATING effect on RKEs??

RKEs have 1/4 lambda polished lenses, and MgF2 coating, vs ES 24mm and Plossl 32mm which have Fully multicoated lenses, but very interesting thing is that even with MgF2 coating, RKEs image is much brighter and image is more...CLEAR, do not know how to explain till you try!

FOV in RKEs seems MUCH larger than specifications tell...

Now I use only RKEs 28mm on my bino, with GPCs and barlows, which is also GREAT for planets!

I sell all my eyepieces, including Baader Genuine ORTHO 9mm and 6mm, and only RKEs stays!!!

So a pair of Televue Plossls of similar focal length wouldn't be as good?
I d like to get a pair of these but the testimonials are so hit and miss. One camp sais the new ones have poor QC another sais they're fine.
WHY. They are so good eludes me and why wouldn't Temevue for example make a similar performing ocular - or do they?

Thanks!

Denis, glad to hear you are loving BV'ing with the RKE 28's. I tried (in WO BV'er at that time), but holding the view was tough so I sold one RKE and kept the other for monoviewing. I was using my 8SE on the AT Voyager mount, perhaps it would have been easier if I was using the GoTo mount with tracking. I only gave the RKE's one shot, not enough, may have to pick up another one down the road and give it a real shot.

TeleVue 32mm Plossl are for sure excellent eyepieces, but I bet that RKEs 28,7mm produce brighter images, and indispensable floating effect in which eyepieces simply dissapiared!

Even if TV Plossls produce sharper images on edge of FOV, I will never replace my RKEs with them, or even ZAOIIs!!!

You must simply see to beleieve, and not enough to see just one fast time, but find out your comfortable view, and when you compare them as I did (approx 4 hours of comparing with ES 24mm 68" and Plossls 32mm GSO), it is clear which is winner in regards od light transmittion, image chrispness and...FLOATING effect!

Once you loves them, it is hard to let them go, and that is the reason why many owners of many expensive eyepieces, keeps RKEs in their eyepieces case!

I will for sure never let them go!

Believe it or not folks I have gone back to RKE's for just about everything!
I have had Naglers, Brandons, Meade SWA's and just about every Super/ Thousand series eyepiece.
I cut my teeth on smaller fields so they dont bother me the least.
RKE eyepieces are flat GOOD! plus they are sweet looking
(Red's my fav color) I have found no lens that is sharper and brighter in the center of field than the RKE, so for fine Planetary/Doubles detail they are Awsome.
I even use them as my main observing oculars.
I had a set in the mid 80's and bought into the Super Expensive gig for awhile.. but I always missed them.
Nothing against the other Brands mentioned at ALL.
Nothing beats an 11 Nagler on the Moon!
unless it may be a Pentax.. thats another story..
Good choice, there is a reason they are some of the longest running series of eyepieces made virtually unchainged since
the 70's.
My favorite set are the 15 RKE's for my BV.

I like also the 15's on the binoviewer, I have doubles on 8, 12, 15, 28, missing one 21
To be honest it is difficult for me to use the 28's on my maxbrights (I am new to bv).
the 8's with 2.6 glasspath corrector in my 80mm Stellarvue apo show great great detail on Jupiter.

So, can someone explain what the "floating effect" experience is about that I keep reading about?

I used to have and old 32mm Brandon that had a very large eyelens that took up the whole top of the EP and was only about 1.5" long. It had a large eye relief and I had to hold my eye way back to see the image. In a way it was as if it was floating in the air, is this what they are talking about with the RKE?

Thanks,

Bob

the Brandon starts to approach the floating magic ..but really, not close. The 28 is in a class by itself.
