Description

This image is a 2 panel mosaic with the goal of bringing out the surrounding dust near M45. I was careful to correctly color balance the image which resulted in a bit of reddish purple near M45. I'm guessing it's a mix of a little H-alpha and reflection nebula? The dust around the center of M45 lost a little detail due to the agressive stretching elsewhere. Startools can leave some halos around brighter stars with the stretching mode I used. Exposures were kept short at 50s and each panel had 120 exposures. It took quite a long time for APP to finally spit out a final stacked mosaic on my 4 core computer.
