Deep Trifid Nebula, colorPosted By Ron Wodaski |
I did the final testing of the control software for the remote telescope in Chile tonight, and managed to grab a 20-image sequence of the Trifid. Individual exposures were just 30 seconds, but the system has a reducer and operates at about f/7 so the end result has really good S/N. Taken with AP7p camera on C14, Paramount GT1100s, using f/6.3 reducer.
Color is from some older images of the Trifid taken with my former refractor (FCT-150). The depth of the luminance image allowed me to really push the brightness in the dim zones, yielding some subtle and interesting colors one often does not see in this nebula.
Sharpening is all unsharp masking; I'm going to try some deconvolution because of the great S/N.
