New Explore 12mm 92 degree is in. Game changer
« on: December 30, 2017, 04:12:31 PM »
The new Explore Scientific 12mm 92 degree eyepiece with 20mm of eye relief is in and it's quite impressive.  It really takes wide field and observing comfort to a new level. It turns out the fov is more like 95 or 96 degrees when comparing to a 13E. After using it at the WSP I knew I had to have one since I use glasses at this exit pupil to alleviate astigmatism . The eyelens is an amazing 1.75 inches across which might be about the biggest one on the market. It's no wonder that David Leavy said this was his favorite all time eyepiece when using the prototype. I love my 13 Ethos and will do a comparison when we can get some decent weather here in Chicagoland. ...Attached Thumbnails

I did some early comparing at wsp and my initial impressions were that the performance of the ES was comparable to the amazing Ethos. The differences between them if any will be very minor from what I was able to tell. ..

Have you compared it to the ES 14 100?

So you used the eyepiece with your glasses and everything was hunky-dory? Have you ever used any other long eye relief eyepieces, like XWs or Delos and can you compare the ES92 vs those?

You seem quite stoked about the ES92, but I'm wondering if that is just because you are in a very small minority that was trying and somewhat succeeding (?) with using an Ethos with glasses on in the past and now the additional 5mm of usable eye relief is the game-changer for you (~13mm usable eye relief for Ethos vs ~18mm usable for the ES92).

Unconcerned with eye relief, I hope to hear the clarity and transmission is top rank. How it stacks up to your TVE13's optical performance should be revealing. For me, that is the critical piece. I look forward to your analysis when you get some cooperative weather.

The thread title says "game changer" but nothing posted so far explains why that is.

Syed I have owned XWs and own 2 Delos eyepieces and used them extensively. They are about as comfortable lines of eyepieces ever made. While this eyepiece doesn't have an adjustable eyegaurd and does only have a rubber eye cup that I don't use, the comfort I get when wearing eyeglasses is very good. All other 100 degree lines don't have this level of comfort when used with glasses.

Been using the 17mm version for a few weeks now and agree - this is a game changer. Compared directly with the 17T4, I find that the new ES is actually a little sharper along with the extra 10 degree AFOV. I've already ordered the 12mm too.

Please let me know if both versions have blackout problems during daylight use.

Thanks.

Do you have any comments on distortions, edge of field and the like?

Thank you Darren. I was also thinking that if the eyeguard was removed, maybe I could squeeze out another 1-2mm of usable ER.

If it is not too much trouble, could you post a pic comparing the ES92 eyelens vs the Delos eyelens? Another question... How did you manage to get the 12mm, I thought only the 17mm was available currently?

Here ya go. The Delos eyelens is just under 1.5 inches while the new ES 12 is a solid 1.75 inches. Daytime testing in a C8 showed no ring of fire effect and a slight amount blackout with a wandering eye but certainly nothing to worry about. I'm not sure when I'm going to have a chance to use with a fast dob again. But perhaps soon with my f/6.9 I will.  Also I was at the Winter star party of course and Greg treated me very well and was able to place an early order for me so I could possibly be the first to have one of these 12mm versions. ..Attached Thumbnails
