||This image was processed entirely in Images Plus.
No calibration was used. The image was brightened using a LMS combine
of two arcsinH stretched versions, one to get the core detail and one
for the faint outer areas. Masked noise reduction applied to the
background using a frequency domain lowpass filter and the multipoint
background flatten tool used to remove the light pollution gradient. No
sharpening or star reduction has been applied to the image.
