Re: NGC 1977, Running Man nebula in Orion
Still Almost finished.... :o A few more luminance images perhaps? We'll see.....
1[sup]st[/sup] image is narrowband Ha, OIII, SII mapped RGB as the Canadian-France-Hawaii Telescope team (CFHT). The Hubble tricolor palette, in which SII, Ha, and OIII are assigned to R, G, and B, respectively didn't look right.
2[sup]nd[/sup] image is a combination of L, R, ,G, B, Ha, OIII, SII taken using GRAS 7 in Israel over 3 nights.
