Quote:At long focal lengths a Nagler 31 will be better but you'll see coma there too. Personally, I'll get an ES82 30 soon but most times I use my 20mm ES100.

Personally, I'll get an ES82 30 soon but most times I use my 20mm ES100.How is the 20mm ES100 working as far as coma goes? I have the same telescope but haven't had a chance to do a first light with the ES100.
Quote:I just received the ES82 14, which I decided to get instead of the ES100 14, to save money/volume/weight/waiting time, since at this focal length I jump 2x and I rarely need something in between.

KKokkolis, by not getting the ES-100 14mm, you're missing half of your life! Joke. 14mm ES 100-deg & 82-degTried my ES-100 14mm on a 16" Newt, and the majestic views wowed me and the astro-buddy who owned the scope; I think it will do as well on the 12" Dob.Best,
Quote:Hey Gene, are you going to post your thoughts on the Ethos/Delos comparison seeing as you have similar focal lengths? I would be interested to know.
Quote:the best ep I found was to first buy a Paracorr
it made a difference with all the eps
Quote:If it was smaller than the 20mm I would get it. I almost got one sometime ago. But I can use a barlow element I have to make the 20mm equivalent to 15mm with almost no weight gain and, since I had the older ES82 14mm (the same you have) and liked it, I decided to get the newer version that's easier to use.
Hyperions are good, but better with a 8" f6 and even better with a 6" f/8 (great at f/10-f/15 also). With 10"-16" f/4.5-f/4.9 one has to spend some more, perhaps for a Paracor.
