Hi all!
I was playing around with my new OIII filter last night. Up till now I had been concentrating on PN, but I had read that certain emission nebula came up well under OIII. So I checked out the ones that I had read about and were nicely positioned: M8, M16 and M17. M8 and M17 were particularly good. Fantastic contrast and the dark lanes were so much clearer. The filter really did its job. I then had a thought... since the article I had read was northern in origin... maybe the Tarantula (NGC 2070) would also come up good.
Now I live in the suburbs and Dorado was low to the horizon, so the viewing should have been awful... but the OIII filter made my heart stop! The detail! The contrast! Now, maybe under darker skies the difference would not be as great... but for me in my light affected backyard I could not believe the amazing sight I was viewing! It has been a while since I have observed the Tarantula nebula but I am glad I made the effort.
For anyone in light polluted skies (or any other)... if you don't have one, grab an OIII filter (mine was only $60 from Andrews) and have a look!!
