Description

Work in progress, trying to get as many subs as possible. Tracking remains somehow erratic, probably due to my mount being pushed to its limit. Original image scale is 0.91"/pixel, here rescaled to 50%. Raw files were first converted to linear TIFF files, then stacked using DSS and finally processed in Startools. The resulting image was slightly tweaked with Photoshop.
