Spent a plesant 90mins with my 10" f4.8 Newtonian reflector early in the night. Cruised around Ara, Pavo, Corona Australis and Scorpius with the 14 82...among others. With no coma corrector the 14 starts to show coma from 20% out....by 50% it stays much the same to the edge lots of coma and probably FC in there too but impossible to see. There is also the usual ES colour fringing showing itself too. The 14 is the worst of the 82's I have with the colour.
Rule one...for me at least....don't use a fast reflector without a coma corrector.
With the coma corrector, mine is the ES HRCC, it's a different story. A few minutes finding close to the right setting and the stars have very little coma, still a bit of false colour.
Also tried the ES 30 18 and 11 82º....all of them get the
from me...specially the 18mm.
The 14mm....I like it in the reflector (more so than the ES 16 68 which I also briefly tried) the 14 82 is better in this scope. With the CC in the focuser FC is there 80% out, but not annoyingly so.
What's to like....
Can see the whole field easily, no eye placement issues...that is no blackouts or kidney beans, just easy on the eye. Not a perfect eyepiece, but as with all the ES line 90+% of much higher priced alternatives.
Last on the list is my 6" f12 refractor....TBC.
