| Date/Location Notes |
28 September 2013 - Las Cruces, NM Published as Astronomy Magazine Picture of the Day, 1 Oct 14 (screenshot). Published in Milenio Newspaper (Monterrey, Mexico) pg 12, on 15 Dec 2013 in an article written by Cesar Cantu. Thank you, Cesar! Picture of article, here. Process notes: Result strictly HaRGB, where Ha was used for Luminance. A test process of Ha_HaRGB (similar to what was done in the NGC6888 result) showed little improvement for this particular object, thus I did not use it for this result. |
