Processing

Calibration, stacking done in Images Plus and an arcsine stretch applied. The feature mask  tool was used to split the stars from the image and a mask made from the nebula only image. An arcsine stretch was used again on the original unstretched image with the mask to keep the stars small. The result was again split into stars and nebula images and the nebula underwent masked stretching and noise reduction. The star layer was then recombined with the nebula. The core shot was processed similarly and resized, then a LMS combine was used to maintain core detail using the two images in Paint Shop Pro. The contrast was enhanced using the clarify function and the image was sharpened a bit using a high pass filter. Finally the image was reduced for web display.
