Think they even get stuck in a clicklock or self centring eyepeice holders?

I've found It depends really on the particular cut back and eyepiece holder designs.

 

My Sterling Plossl cut backs are a steep taper and long.  They are a disaster in my Denk II and Bino-Tron (wiggle around and are a bit off-axis) but work ok in MK Mark V.  However, with my MarkV, I can't slide the right eyepiece out slightly for focusing of my right eye relative to my left (the fine focus collet in the right holder is frozen).  Straight cut backs seem to work much better than the tapered ones in my experience.  Of course, NO cut back is my choice.

I chose the 21mm LOA and sold my Pan 24's.  I found the 21 LOA eyepieces more comfortable to use than the Pans and they do not have those stinking, awful, rotten, no good, lower than a snake's belly, and stupid undercuts.

:lol: I guess you don't like them!

I would keep both. 24mm Pans are still my favorite for serious observing. LOA 21 3D are just for fun and work best on open clusters, and milkyway.

P.S. If you just go with LOA 21 3D you probably would want the 3rd eyepiece for 2D detail viewing.

Hi, I'm getting a 2nd 16mm Nagler soon. What do you mean a 3rd ep for detail viewing? Another 21mm to go with the 2 LOA's for regular viewing?

So which of the 2 would you use more on any given night? Strictly for DSO's. Which feels more comfy and let's your eyes sink in better? Like bunoculars.

 

They are very comfortable to use and my eyes do sink into them. They are very nice for open clusters, which are my favorite objects to observe. I may have to sell my pair of Meade 20mm SWA and get a 3rd. LOA for non 3d effect. Also, they are a lot lighter than the 20mm.

I just wish I could view a picture somewhere on how the image looks. A grand US is a lot of money for some us Canadians now lol. 

 

They made binoculars too wow... http://agenaastro.co...-binocular.html

 

REC old buddy how are you?...I remember having many binoviewing eyepiece combination discussions with you in these boards.

 

Nice to hear you got and are enjoying the LOA 21's. Ok I'll crawl back into my regular eyepiece discussions and leave ya'll to your 3D viewing lol.  :step:

Yeah, I was tempted to try these binoculars, but I have too many already in that size and don't have an extra $300 to spend. Actually I need to start selling some stuff I don't use.

 

The LOA eyepieces are great and not just for 3d viewing. They are extremely light and compact with great eye relief, which make them very comfortable on your eyes. Also they don't have those nasty undercuts that I hate! I find them to be very sharp and contrasty more than other EP;s I have in that range. I should probably sell the other pairs I have in that range and just buy a 3rd. non 3d LOA. I use the LOA's in my Denk II with my 8 and 10" scope. I use them in a lightweight pair of WO BV in my C102. I have it set up so that I don't need a barlow or an OCS to get it to focus. Nice wide fields of stars and clusters look great in them. The double star cluster is one of my favorite  objects to view in 3d. The best way I can describe it is that it gives you a sense of depth in the views. They are not good for the moon and planets as you would see the shadows of the arrays in the eyepiece. I mean you can use them, it's just that you would have to move the scope around to find a sweet spot so not to see the array.

 

The other objects that do well in the LOA's are globular clusters....pretty cool view. M42 is also pretty nice because it's so big and bright. I have used the setup both ways, with and without a nebula filter. M27 is cool too, because it sits in a nice star field and you can make it pop to the front of the view.

 

Looking at your you sig line, you sure have a lot of nice gear! One thought, if you did buy a pair and where not really happy with them, you may be able to return them to Russ in under 30days? Also they would sell used in a snap, say for $500 US.

 

Clear skies, lot's of good stuff out now to observe before the deep freeze comes up the "eh!

Rec, as I used to tell you a few years ago, take a pic please. lol I'm curious to just see one picture with the LOD's on any binoviewer. I'm really liking their shape. They look like exactly what I was looking for a few years back when I tried all those weird eyepiece combos.

Go to Agena's website, they have good pictures of the LOA's you can look it. There are 3 views of them, just click on to blow them up. Also, you can see them on the Denkmier website.

Observed DSOs from my driveway Friday 2/17/2018 8:30PM-12:30AM Saturday 2/18/2017 with binoculars and
then with my f4.1 17.5" Discovery Split Tube Dob and ST80 finder. Second use of Vision King 5x25 binos that I
received in May, and second time I looked at winter DSOs with the 8x42 Space Walker 3D binos. Nice clear new/no
moon night with light clouds near SE horizon when I stopped. One new neighbor kept 4 bright outside lights on
all night, and did not answer his door. It was fifth use of my new 2" GSO focuser/diagonal permanently
installed on my Orion ST-80 mm finder with 2" Nikon 17mm HW 102 AFOV eyepiece with EIC 14mm (w/o
spacer). This time I used my Denk II 3x3 binoviewer w/ Newtonian OCS and LOA 21mm 3D eyepieces in my 17.5" dob.
I liked seeing the objects change depth as they drift through the sky in my manual dobsonian.
Looked at DSOs in Canis Major, Monocerus, Gemini, Orion, Lepus?, Taurus, Auriga (near zenith), Cassiopia?, Perseus,
Andromeda, Triangulum?, and Leo. Since I just rolled out my dob from the garage I did not re-collimated my dob, nor
re-allign my Telrad and ST80 finder, and I did not use the Paracor II this evening. I used my perminent Astrocrumb
filter slide with my 17.5" (not ST80 finder) to look at emmision and planetary nebulaes unfiltered (natural), skyglow,
ultrablock (good contrast), and OIII (greatest contrast, fewest stars). Found most objects from memory, but briefly
used O'Meara's "Hidden Treasures" and Brent Wattson's Telrad charts for help when needed. Last objects looked at were
in the light polution of my neighbor to the north and then Leo which was rising above my house. In addition to it being
very cold below freezing with snow on the grass, my back and shoulders were sore from aiming my Telrad near the zenith
for Auriga's clusters and wearing so many hooded sweatshirts, facemasks, hooded down jackets, and deep sky apparrel
long hooded vest. The latter was great for masking out neighbors light pollution at the eyepiece.

Listed from lowers power widest TFOV to highest power and lowest TFOV.

Space Walker 3D 8x42 15.8 deg Binoculars (used first/second) - very clear except when bright stars were on edges of
arrays creating artificial doubles. Able to change depths of objects by slight left/right panning:

Dob thanthan in the ST80.
*M35 but NOT NGC2158

P.S. Got up this morning hoping to look at Markarin's Chain, but with the full moon and dawn approaching 3/3/2018
6-7AM only able to look at Jupiter, Mars and the near Full Moon. Used 4.7mm Ethos in both my 17.5" f4.1 dobsoian w/o Paracor II,
and Orion ST-80 finder. Looked at Jupiter unfiltered (2 bars and redspot?), skyglow (two bars & redspot),
ultrablock and OIII. Trees prevented me from finding/seeing Saturn.

HL/HM/HH powers all unfiltered. 3D not really noticable on this dim object in ST80.
*M35 but NOT NGC2158 dim in ST80 and hard to see in LL mode, but gets easier with higher LM, ML, and LH/MM/MH,
HL/HM/HH powers.

Nikon 17mm HW 102 AFOV with EIC 14mm (w/o spacer) eyepieice in Orion ST-80 finder (3.57 deg TFOV, 29x, 2.8mm exit pupil) used second:
*Orion Sword: NGC1981(HT30)/not NGC1977(Not HT32)/M42/Not M43/Col72(HT31)/Not NGC1999(Not HT33) - Nice view of entire sword unfiltered
*M45 Plieadies Cartoon Rat in dress Able to see all of it
*C41(Mel25 Hyades V or Z/N) had to pan to see all of it but could make it out
*M44 Beehive able to see all of it
*C39(NGC2393) Eskimo nebula not able to see in finder
*M35 but NOT NGC2158

Nikon 17mm HW 102 AFOV with EIC 14mm (w/o spacer) eyepieice in the 17.5" f4.1 Dob (0.78 deg TFOV, 131x, 3.4mm exit pupil) used first:
*NGC1981(HT30)/not NGC1977(Not HT32)
*M42/Not M43 (unfitered OK, skyglow better, ultrablock great, OIII best but some stars disappear).
*Col72(HT31)
*Not NGC1999(Not HT33)
*M45 Plieadies had to pan to see all of it
*C41(Mel25 Hyades V or Z/N) had to pan to see all of it but could make it out
*M44 Beehive had to pan to see all of it
*C39(NGC2393) Eskimo nebula (unfitered OK, skyglow better, ultrablock great, OIII best but some stars disappear) much better in 17.5"
Dob thanthan in the ST80.
*M35 but NOT NGC2158

P.S. Got up this morning hoping to look at Markarin's Chain, but with the full moon and dawn approaching 3/3/2018
6-7AM only able to look at Jupiter, Mars and the near Full Moon. Used 4.7mm Ethos in both my 17.5" f4.1 dobsoian w/o Paracor II,
and Orion ST-80 finder. Looked at Jupiter unfiltered (2 bars and redspot?), skyglow (two bars & redspot),
ultrablock and OIII. Trees prevented me from finding/seeing Saturn.

Wow, what a night! Never thought of using them in my ST-80. I have an old Celestron version and not sure if the stock focuser would handle it. I'll try my WO which is lighter.

 

Last night I had them in my C102 and no need for a barlow to get focus. Had a wonderful view of M42 with an Olll filter in my Meade 20mm SWA.
