    Description

    My first mosaic using PI. A combination of 4 frames of ~ 30x20 arcmins covering the majority of M33.

    The pre-processing is pretty intensive - it took several hours to get it right, combining the files, cropping them, making an initial mosaic, then using the gradient merge to take out the joins.

    So, at least 3 hours of processing to get this - but I have learned a lot and will try again with other subjects.
