This is my second processed image using my new Rig , as you can see im slowly getting there with my image processing.

I have both Pixinsight and Photoshop CC however I can't seem to process well in Pixinsight and only use for registering images , all image processing is done in Photoshop CC 2019.

I have also learnt how important the luminance layer is to a successful DS image.

Very lucky to still have my rig , slept through my alarm early hours this morning , just as I got the rig inside before work it hammered it down with rain, won't be doing that again.
