M13 reprocess

[bomberbaz]

Hello all.

I first captured and processed M13 cluster in mid May. There is only half an hour of data and the first image is processed via Gimp only. However  having recently been introduced to Siril I am doing my initial processing using this and then tidying up in Gimp

I should mention that I installed Py-astro tools to gimp and there are some very useful tools in this add on. Notably red sky purge and star enhancement, the latter came in handy with the second image.

So the latter image is pre-processed in Siril, then onto Gimp for finishing. (Forgot to crop 2nd image)
