M45

The evening was surprisingly clear for one with clouds in the forecast so I headed out to SCO, the observatory of the Halifax Centre of the RASC for some time under the stars. As I finished polar aligning several other member arrived and began lugging their equipment out and setting it up. The first target for the evening was M45. I was able to collect about 40 minutes of data before my second target, M1, rose high enough in the sky to image.

I used short exposures to preserve colour in the stars and lots of subs to bring out the nebulosity around the brighter stars. The short sub-exposures prevented saturation of the fainter stars so more of the colour gets maintained during the stretching process and after the initial stretch, split start processing ensured that the star colour was preserved throughout the rest of the processing.
