ES 8.8mm. is the 11mm as good?
« on: December 24, 2017, 03:20:08 PM »
I am using the ES 8.8mm 82 degree with a 150mm F12 mak and its lunar operation is extremely good.  It shows exceptional sharpness and scatter control, and I see no curvature to mention.
Does the 11mm perform in addition to the 8.8mm?

<p>Sure. </p>But only since I had both and employed equally, not because they'd typically be put head-to-head; they're quite different EPs.

Aside from the substantial AFoV gap, the ES has relatively very short ER compared to the XFs 18mm.  I think the XF is quite good for lunar and utopian, though not perfect.  If you think the ES is very good, I doubt you're most likely to find the XF better.  However if you're binoviewing I would say definitely attempt the XFs.  I suspect that the XF may seem a tad sharper on-axis, with better comparison, though have a little bit of off-axis color smear compared to the ES.  Irrespective of some articles asserting that XFs have lesser coatings than various other EPs, or show internal reflections, I've discovered the XFs to become razor sharp on-axis and with exceptional transmission.  (The XF 12 reveals field curvature but it flattens out within my refractors using a 2x amplifier/corrector onto a bino.)

Though I've used T6s and XWs more on Jupiter, and ESs many times, the most detail I've ever seen on Jupiter with my scopes was binoviewing XFs at 2x with my 4" APO doublet (147x and 207x).

Does the 11mm perform as well as the 8.8mm?
It's even better.Clear skies!

Well, the OP made my post look strange and out of place...

Before he edited both the title and the post, he was asking about the Pentax XF 8.5 compared to the ES82 8.8. There was no mention of the ES82 11.

Before it changes again...FWIW, the ES82 11 is well regarded by many, but I thought the 8.8 was a better EP. I thought the 4.7 and 6.7 were the best of the line. However, at the FLs I used most, I ultimately preferred the T6s.

IMHO, the 11mm ES82 Is the best of the series, along with the 24mm

Thanks for the explanation, slack. I was scratching my head for a minute trying to figure out where your first post came from. Funny now.

I have the ES 11 and 6.7. The 11 is my favorite and I've read it's a lot of people's favorite. A lot may depend on the particular scope used.

Hi to everyone.

Would any of you be a fan of the ES 82° 14mm instead of the 11mm for Mars, Jupiter and Saturn?

I didn't use the 14mm much when I had it, pretty much went from the 18mm to the 11 or 8.8mm. This one is known to have some field curvature issues. The 11mm is great for DSOs, nebulas, galaxies, etc...the 8.8 is good on planets (as is the 6.7). The 24mm, 11mm, and 8.8mm were the ones I used the most in my dob.

Never used the 8.8, but I own the 11mm and it is a fine ep.

I, like rowdy388, have both the 11 and 6.7 from this series. Both are great eyepieces for planetary or deep sky. The 6.7 seems to have a little more eye relief, which I think is due to the lens being sunken in a little more in the 11 along with it being a concave eyelens, vs the flat plano lens on the 6.7. I still recommend the 11mm

Here we go. If the ES 82° 11mm currently costs about $149.99 and the Baader Morpheus 12.5mm costs about $199.00 on Eyepiecesetc.com and the same sales price on Agena Astro website, wouldn't it be worth trying out the Baader if someone can afford the extra fifty bucks, of course?

Apologies for the edit of the initial title. I was wondering how the 8.5XF compared, but i then decided to stick with comparing to the ES 11mm. However i must say the images in the ES were impressive, and the 82 field did give a certain wow factor.

Definitely agree here should the OP want to buy new. Now if the OP looked on the used market, the 11 could be had for $100-$110.

IMO, it worth trying. Check out these reviews ( review 1, review 2, review 3). If one can't afford TV Ethos/Delos, the Baader Morpheus would be a nice alternative, it looks like they are in a higher league than the ES82s and are competitors to the TV Deloi.

Yes I am, but only when used with my 2.5 powermate. It is just the right magnification on some nights for Jupiter or Saturn as it fills a gap in my short focal length eyepieces.
