Re: [APML] Up-Scale eyepieces



Hi Glenn,
  I've owned quite a number of eyepieces and sold or traded most all of them away.  Without a doubt "the best" single one I ever owned was a 16mm Nagler.  I've heard about all the light loss from extra elements but after comparing that particular 16mm to even various orthos it always came away the winner.  Better by far than Vernonscope Brandons (never buy another thing from that guy as long as I live either) on planetary detail, very nice for some deepsky too.  I've no experience with Radians but have heard only "great" about them.  I had a very nice 7mm Nagler too, but pretty short on eye-relief.  Remember some of these might be difficult for eyepiece projection photography.
  After looking at a few links posted earlier today and somehow happening to recognize an institution's name, you appear to not wear glasses <G> and likely use both eyes extremely well <G> so the 31mm Nagler may not bother you.  I do wear glasses and often observe without them but even so the 31 Nagler I owned had very little eye-relief.  I don't remember what it's quoted as, but it definitely appeared to have much less.  I really disliked that and found it very bothersome for the price.  I sold it because of this.
  A better low power eyepiece is the 40mm Pentax XL.  The first one of these I owned was right after they were introduced, it was absolutely spectacular and came in as the second best eyepiece I've ever owned.  But I traded it away!!!  Unfortunately, I bought a second one a couple years later and it was not nearly of the same quality.  I returned that one to my dealer for something else.
  I'll mention I have a Meade 24.5mm Super Wide Angle that I like very well as a great all around performer, very surprisingly so.  The University Optics orthos are a real bargain and I have two of those.  Finally, a Meade #140 2x apo triplet barlow I have seems to be the best barlow by far that I've ever looked through (I know, it's a Meade...).  The moral of my particular story is if you get your hands on a real performer never part with it as they seem to vary within the same make and model even.        
 
 
Best of luck, I know you will be sharing some truly excellent photos,

Subject: [APML] Up-Scale eyepieces

Though this is a list on astrophotography, we have to frame up our pictures and glimpse the telescopic sky scene before putting in the inevitable CCD autoguider! I suspect that these moments of looking at the stars while out trying to photograph the stars are among the most pleasurable of all for us in this hobby. In this regard, what eyepieces serve the best?
 
In particular, on this question, one can spend quite a lot on quality occulars. At the recommendation of Jon Kolb I purchased a Takahashi 5 mm focal length occular with LED-illuminated reticle for guiding purposes. This was expensive!! But it's worth it: the occular has excellent resulution to the edge of the field, good eye relief and fine mechanical quality throughout, especially in the engraving of the reticle.
 
Nagler-type eyepieces are judged to be good quality, so I hear, and those that have attempted to copy Nagler eyepieces have sometimes fallen on their faces, so I hear from the grapevine.
 
Do any of you have eyepieces that you are especially fond of?
