Description

Well for the third year in a row, I've decided to image the Rosette nebula. But unlike previous years, I'm now armed with a QHY268M, 3nm Antlia narrowband filters, and a bit more astro wisdom in general (still with my 10" Quattro). So you could say I've been using Rosette as something of a milestone target to see how I've progressed in this hobby. Anyway, after spending the better part of Christmas eve processing my 46-odd hours of SHO-RGB data (that I kept), this is what I have to show for it. Unfortunately, my field of view isn't wide enough to get the whole nebula (extra half degree would help a lot) so there's some nice outer regions (H-alpha rich) that can't be seen. What this meant practically is that I wasn't willing to push the [OIII] to much or that's all you would see. Because my tone map approach to doing an SHO composite gives largely white stars, I decided to incorporate some RGB stars into the image.
