12.5mm Docter Eyepiece

I have read many ' glowing ' reports about these ....

......has anyone here ' looked ' thru' one.

Docter is an amazing unique ep with some German voodoo thrown in (aspherics??)

im not sure if anyone in Oz has one -but i presume there is atleast 1 or 2..reviews on CN put it at one of the best ep's around..some like it better than ethos. im pretty sure John B posted about it a yr or 2 ago -when one of his US visitors dropped it into a focuser for him

you might as well get a leica asph zoom -covers 8.9-17.8mm

Yep - John B ausastromer reviewed it - basically the best EP he has tried coupled with one of the biggest prices

According to many owners on CN who have this eyepiece.... it's an absolute keeper ... never to be ' sold ' .... or the ' very last ' eyepiece they would ever part with.

Some even have 2 of these for Bino use.....

In Europe, it's only 50 euros or so more than a 13mm Ethos...

Make sure you do a review on here when you get yours Flash
I've decided against forking out for it, because a) it's too lumpy, b) I have a 13mm Nagler, which is just what the Docter ordered, and c) it's not a Total Solar Eclipse.

... yeah but by all accounts a very impressive eyepiece... and yes ...one is on its way to me now....got shipping information today from Agena USA.... she's in the post.

Some people may think .. what a waste of money... they would have spent it on other items, let alone a ' single ' eyepiece.....for me it's no different to forking out on any ' high end ' item.


Cost me just under the GST requirement to import it.....only just tho'.

Obviously, this will be my most ' prized ' eyepiece, and will be the first I grab when Scope time is favorable.

Should go well in my TeleVue Genesis SDF Petzval ' Fluorite '


Looking forward to receiving it

Col.....

Everybody has different priorities. Do let us know how you are going with yours (when the time comes). Some comparos will also be appreciated I'm sure.

Now that is going to be difficult for me, as I don't have any focal length eyepieces with the 84* fov .

The only 12.5mm eyepieces I have here are the Celestron Ultima 12.5mm and the Vixen LV12mm ... both very nice eyepieces.... but I'm sure they are not even in the ' race ' .

After I've had good use of it.... maybe I would forward it to a ' trustworthy ' person to deliberate a proper comparison with an alternative ' high end ' eyepiece of similar specs ..... such as the TV Nag' 12mm or TV Nag' 13mm.... both of which are 82* degree fov.... close enough anyway... and possibly a TV Ethos 13mm .. but it is 100* degree fov.....be a good comparison.

Of course...I would want it back ..... ....

I would love to compare it with the 13T6, LVW13 just to see how much difference is seen on axis. I think the mere fact that it is made with the typical German attention to detail would be a big attraction.

I wouldn't recommend you loaning it out though........ the temptation to 'lose' it in the mail would be too great !!!!

Yes ... that's a risk to consider alright .... let me know when you may come up this way again.....bring those eyepieces with you....

We'll have an ' eyepiece shootout ' ....

On another note ....if this eyepiece is a ' jaw dropper ' and is everything and more that it is reported to be .... I will get another for use in my TV Bino's.... let's hope the exchange rate doesn't head too far south...

Very encouraging report.....Bino use.

http://www.cloudynights.com/topic/49.../#entry6554772

extract : from CN posted by Mark

It's fantastic. Probably more than half my viewing is with 2 Docters in a binoviewer, both barlowed and unbarlowed. Yeah in my opinion it's indeed worth it, absolutely a jaw dropping experience. (tec 180, mark V)

extract : from CN posted by Ian

I have only used a pair in the Docter 40x80 binocular but the view is exceptional. I am going to buy a pair to use in my 100mm APM apo binocular. The view is immersive due to the generous eye relief, wide field and large eye lens with very well designed eye cup. Congrats on your new eyepiece. I don't think it will be long before another is heading your way!

and another report from CN posted by Stephan

Another happy Docter 12.5 UWA bino user here. Definitely lifetime keepers! The Docter works phantastic in any bino configuration - just plain 1:1, or focal extended by any Barlow, Powermate or the Baader FFC.

If the focuser of your TV Genesis-SDF can handle the weight of the bino plus a pair of Docters (check up to fully vertical position), do yourself the favour and buy that second Docter.

hmm... I can see myself getting another one ....

Col.....

Certainly an interesting EP. I suspect Docter's actually conceived this EP for bino use.

I'd love to see a set of Abbe orthos coming from this company, given its heritage. I must visit them next time I'm over there.

From a CN post by T Homma the ER is about 20mm

I have given this EP a bit of thought in terms of its physical appearance, discernible dimensions and stated specs. When considering it's size in particular with fov (and especially ER if indeed only around 10mm) I feel the optical mechanics of this EP may be closer to a 13mm T1 Nagler than anything else.

However, having said this I want to stress that a German made glass and coatings can make a gigantic difference (as Dr Zeiss will attest) and there is likely to be a no contest between the T1 Nagler and this Docter
