Description

Sometimes it is interesting to track the progress in acquisition and processing skills. I shoot the same object  two years ago Thor 2022 about the same time of the year.
This version is 8hrs Oiii and 6hrs Ha from december 2023; the weather in Namibia has been bad since, so I took 1hrxRGB stars from the 2022 batch.

EDIT: in praise of deconvolution
For no apparent good reason I didn't use BXT in the image.
Below a crop of the 'helmet' shows fine details in the nebulosity after applying BXT.
