Re: (IAAC) NGC 4216
Hello, Nick. I'm Kent Blackwell in Virginia Beach, VA USA. I last looked
at N4216 with a 12-1/2" f/6 back in March of 1992, and remember seeing it
as gorgeous in my 6" f/6 Celestron Newtonian telescope. What a wonderful
area surrounding it as well. Page 193 of my Uranometria is filled with
notes. Great field around this stunning galaxy.
I just observed the Witchead Nebula in Eridanus last night. It's eluded me
previously, but managed to see it at 90x with my 16" f/6.2 and a Lumicon
Deep Sky filter. Normally I like the OIII filter, but the Deep Sky was
best on this. Looks like a faint California Nebula.
