Quote:I have to agree with Stephan and say the 10E is my most used eyepiece in my 14.5" dob. With it's 2mm exit pupil is seems especially made for observing galaxies from a dark site. If I was to do it all over again (with gained experience) I'd choose the 21/10/6 progression with exit pupils of 4.2, 2.0, and 1.2mm respectively.

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe

Quote:I am contemplating buying another ethos,probably 2 at some point. I need to go one at a time though. I would be selling some ES82 and eventually (maybe) my ES100 9mm. Only the ES82s near the ethos focal length would be sold. what i am thinking is to buy either a 13e and sell my 11,14,18 ES82s or to buy a 8e and sell my 8.8 and 9mm es100 and 18mm ES82. Right now I am leaning heavily toward the 13e. In both examples the 18mm gets sold because I have a 21e now and don't need the 18mm.

Quote:I have only owned and used the 13mm and I would recommend it. Also, in a 12" f/5 dob, it would be one of the most used FL's yielding 115x with a 0.9* TFOV, a good place to start I would think.
Quote:I wouldn't buy for 3 reasons, and these are all personal.1. If I was to buy something astro related that costs hundreds of dollars, I would rather buy a new primary/scope as that is a better use for my situation.2. I sketch and it is handy to have the edge there for reference when sketching. Less FOV is less to have to sketch.3. I also star hop and it is handy to know the diameter of the FOV for measuring distances.They seem like great gear, and if I wasn't so into sketching and record keeping, I would prolly go with the 21mm. In my scope this would be 2.1mm exit pupil, 50x, and maximum FOV
