New EPs for Binotron
      #5789326 - 04/09/13 11:05 PM

I have a pair of Pans 24 waiting for Binotron's delivery.
What would I gain by having also RKE 28mm or Brandon 32m pair ?
Scopes Apos 101 f5.4, 105 f 6.2 or 130 f6 (deciding which to keep), Schmidt Newt 6"f5 and Dob 16" f4.6...

Hi Daud...I don't think you'd gain anything. The 24 Pans offer a larger field than either of the others (and certainly higher optical quality than the RKE's). The 32mm Brandons will probably have some negative eye-relief issues vs. the Pans.

I have the 24mm Pans and 32mm Brandons Daud, and I like the 32mm Brandons for their flat orthoscopic field. The Pan 24s are awesome, sharp, and great for deep field - but they have quite a bit of pincushion distortion. I also find the Brandons noticeably better on axis for planetary, just a hair sharper and with less scatter. But you would be fine with just the Pan 24s. That being said, I am on the lookout for a pair of 28mm RKEs just out of curiosity. I had a pair from Surplus Shed but they were extremely defective, I'd still like to see what the fuss is all about.

When I have tested 28RKE vs ES 24mm which is simmilar to Pans 24, without doubt winner is RKE28!!!

Right, same here. I also got a pair from Surplus Shed and they were extremely defective... dirty, little scratches, dust that wouldn't come off, and the barrels (and I think even the eye lenses) were slightly different sizes. That said, I enjoyed binoviewing with them, but the Pan 24's got a ton more telescope time.

Surplus Shed do not sell them for a long time, so the best is buy them directly from Edmund!

I like my Pan 24's best of all, they are very sharp and easy on the eyes for extended periods. I have never tried the Brandons but the RKE28's are bright and fun to use,( they really do make the stars seem to float in front of your eyes), my only issue with them is the 24mm+ of eye relief makes it hard for me to keep the view centered without any kind of eyecup. (If you wear glasses to observe? they might be just the thing!)

In what criteria did you find the 28RKE's beating the 24Pans? 24Pans have high light transmission and resolution for their amount of optical elements. What telescope did you use in your testing these eyepieces? Your 10" GSO? Is it an f/5? Did you use a Paracorr? What visual objects did you base your testing on? Are these two eyepieces about the same physical size and weight?

Peter,
Pan24's are larger and heavier than the RKE 28's.

My love of my 28 RKE's is similar to Denis0007dl's, however, I have never tested them against any premium glass as the 9 pairs of eyepieces that I have available for binoviewing cost less COMBINED than 1 pair of 24 pans (including the pair of new, not surplus, RKE's).

The reason I enjoy them is they are MUCH sharper up to their field stop than anything else I own and they seem, to me, to show more detail than anything else that I own. I barlow them with a powerswitch up to 6.5X and for now, they are the ONLY eyepieces that I use when binoviewing. (With my powerswitch on my 10" Z10 I can get 60x, 99x, 120x, 148x, 197x, and 291x using the 28 RKE's.)

They are certainly cheaper than the pan 24's, but the pan's are going to offer a wider field of view.

Is their anyone that can loan you a pair to try out?

They are an acquired taste for sure, but I LOVE mine. (Look up my other posts for my past RKE ravings.)

Peter T.

In my experience between RKE28 vs ES 24 68", simmilar to pans 24, RKEs clearly wons, picture is brighter on f/5 newt, stars are beautiful diamonds, picture is more clear, and fantastic floating effect that not even Pans have!
Of course, they are also lighter and heaper, but even RKEs would be same price and weight as ES 24 or Pans 24, my choose would be RKE 28 without doubt!

Unfortunately, you really can't say that since you haven't compared the RKEs to the 24 Panoptics. The Pans are most definitely a step up from the ES. I personally find the "floating effect" to be severely over-rated as far as enjoyment is concerned. True, it's a novelty; but that novelty wears off after a couple uses and the Pans become my clear winner between the two. For absolute center of field clarity, I switch over to the 24mm Brandons. You can't have everything, it seems, in one package.
