ABSTRACT
The blue nebulosity of M45 for instance is all the more striking when seen in context to its dusty surroundings of the Integrated Flux Nebula. With a range of star intensities and varying intensities of nebulosity, it is a good example to work through in order to explore mosaic image acquisition and processing in practice. The images were taken with a 132-mm refractor, fitted with a non-reducing field flattener. Following the standardized workflow for merging images, each image was calibrated, registered and integrated to form 25 individual traditional stacks. Image integration, removes the RA and DEC information from the FITS header. The Image Solver script re-instates it. The luminance file was processed normally; first with Deconvolution and then stretched with a combination of Histogram Transformation and Masked Stretch. After a little noise reduction, the cloud details were enhanced with Local Histogram Equalization and Multiscale Median Transformation tools.
