Quote:Hi cr500guy and welcome to Cloudy Nights. Is it possible to hang onto the Ethos and purchase a quality 82° eyepiece with a similar focal length to your Ethos to help you decide?
Quote:Tough callI feel the 100 is nice but not really required personal preferance.I actually prefer the 70-82 degree EPsYou can get a few ES 8184.108.40.2061all for the price of one Ethos!
Quote:Although I have a couple of 100 degrees eyepieces I still find 68-82 degrees as suficient, particularly the ones with great eye relief because in the 100s I can see easily around 70 degrees at once, the same amount I see with my Delos and Aspheric and somewhat less than with Naglers T4. So, yes, you can mix them and most people do. Even those with a full Ethos armament get that 31mm Nagler after all. 82 degrees is the closest, so the ES82 is a good option but you might even consider the ES100 that will go from 25mm down to 5.5mm to acompany your Ethos if you decide to go with a full 100 degrees set.

Quote:Quote: I thought of using them for planets... And just because someone's using higher magnifications doesn't mean they're peekin' at planets! Oh my, no. My very first glimpse of M57's central star in my 15" Dob was with my 9mm ES-100, Barlowed up to ~424x... in fact, using the very 2x Barlow i linked above! I then attempted the same with a ~1.6x Barlow ('Barcon') at ~300x... could still get an occasional blip sighting, tho was more frequently spotted at 424x. This has occurred a couple of times from my mag-5 backyard. 'Tis a bit easier from a truly dark site. Conditions plus ample magnification is the key.The advantage in using a 100* EP for such (non-planetary) things really comes into play at these higher magnifications- especially in an undriven scope! The larger field (per magnification) gives you more time to let the scope settle from focusing and/or nudging, and just stare comfortably for a period, awaiting a momentary stilling of the atmo- whence the faint+obscured star may wink out at you suddenly!So one can easily make a case.... for getting these babies outta their case!

Quote: IME, APers and visual observers don't mix very well.
Quote: I try to do what makes sense.
Quote: I preferred the XW for its higher transmission and image clarity, but the extra wide field of the ES 100 9 gave me a more leisurely look.
Quote: Quote: IME, APers and visual observers don't mix very well. No "us" and/or "them" mindset with these guys. We have a blast!
Quote: Quote: I try to do what makes sense. Well, keep trying. It'll come.
Quote: A few great eyepieces are better than a whole box full of second-rate ones.
Quote:I was skeptical about the need for a 100° eyepiece until I purchased one. Now I'm hooked!
Quote:But whatever else ya do, do NOT look thru a binoviewer... lest you develop THAT addiction, as well.

Quote:Too late for me and bino viewing too... glad to say I recall someone saying all you need is a 9mm 14mm 20mm 100* eyepieces and a 2X barlow and you have all you'll ever need. On the other hand I've never regretted selling a Pentax 10 XW and getting 3 ES 82's in its place.One 100*.... only two to go?Matt
