Subject: [amastro] Re: Using O III with higher magnifications ?
I've had the same experience as Rich, that the O III doesn't help on most
extragalactic H II regions.
One time I was set up with an 18-inch all to myself and great skies, and a
list of knotty galaxies I culled from the Vickers CCD Atlas. I was going
to write this great article about how surprisingly easy these H II regions
were with the O III, but I couldn't find any!
There are some rare exceptions, but straight visual appears to be the
best.
