Here is my offering. I like all green labels and eye relief.
These I use for public out reach events. Don't like to use my Nagler's for that.

Paco, Thanks During these cloudy nights its given me time to read and gain knowledge from these great threads on CN. 
John, The T4 Nagler family great for fast scopes and very well known for there eyerelief 12T4,17T4,22T4! Very nice series along with some other fantastic eyepieces from Tele Vue.
2nd pic. members of the hyperion family best value for the amateur astronomer for a long time and maybe still is!

John,
Very Nice collection! May I ask with which scopes you use your Nagler T4's? My reason for asking is, I'm considering filling in the gaps in my collection with the 22T4 and 17T4. I already have the 12T4 and use it extensively as my Sweet Spot EP in my 80mm f/6 APO Triplet and I love it. Plus I'm planning on adding an Orion XT10i f/4.7 when funding permits and I'm trying to buy gear that will work well with both scopes.

I use them in a 20" F5 Obsession and a 10" F 4.7 Orion reflector. I have contemplated a Tele Vue coma corrector but just can't justify it as theses EP's are so well corrected. I also considered going all Ethos but why replace these great pieces. They have wonderful eye relief, contrast, and the views will slap you down. I must say though that the 22mm gets little use. I usually go from the 31mm (80X) to the 17mm (150X) or the 12mm (200X) when using my 20".

JJ,
Thank you very much for taking the time to reply to my questions. I confess I'm a little surprised by your response - on paper one might think the difference between the 31 and the 22 would make that more likely to be used than the difference between the 17 and the 12.

Paco Theoretically following the 1.4X rule for the EP increments the 22mm would be next in line from the 31. The 82 degree field of the T4's kind of blows that rule out of the water.
There is nothing wrong with the 22mm and I keep it just in case I view an object that I want to frame nicely. My 27mm Pan is in retirement because of the 22. Nothing wrong though investing in the entire T4 line if for nothing more than the eye relief.

Paco I see from your signature eye piece line up that you start with the 35 pan so the 22T4 will fill in nicely for you. With me using the 31T5 @ 82 degrees the jump to the 22 seems negligible to me in my 20". I put your 35 Pan into my eye piece spread sheet and the 22 did find a place then especially when looking at FOV.

Newfie Ninja, Another great photo of the Ethos kings! Also fantastic shots of the WO UWA and SWANS. UWA work great in fast scopes and the SWANS in slower scopes! Great Sets!

John, I wonder about the 1.4x "rule". Is it more about actual image magnification (or reduction, I guess in this case) or about inclusion of objects in the field of view? I have obtained eyepieces more with target image size in mind.

Ed The 1.4X is a general rule. It is much like audio in which for a person to perceive an increase in volume there must be a 3db jump. For a person to perceptively note increases of magnification so the 1.4. This works good as long as you do not exceed your telescopes maximum magnification. I believe this "rule" was developed back in the day of narrow field EP's and may not hold up so well with today's wide fields.

I have two complete sets. ZAO-II consisting of four EPs (4, 6, 10 and 16) and Edmund RKEs consisting of 8, 12.5, 15, 21 and 28mm with doubles in 15, 21 and 28. I also have TV Ploessls in 8, 11, 15, 20 and 25 with doubles in every size except 8.
Everything else is one of a few from this line and another from that line of EPs.
