IC 4628 (Prawn Nebula) (finally reprocessed!)

First time in imaging this one, I have a feeling that it is considerably larger than the area that I have done, even if it isn't, there appears to be a fair bit of Ha surrounding this region.
Lost about an hours data throughout the night due to the auto guider dropping out (connection loss). Not sure why it does it, it isn't running through a hub or near any electrical wires. Hopefully won't be an issue in the coming weeks.

It is a bright region so I may just leave it where it is data wise, could add a lot more time to get better SNR but there isn't much faint stuff to worry about. There is only one remotely dark region in the field towards the top left.

Tried adding synthetic RGB stars (combining in HSO), it has worked to an extent on some of the brighter stars but it has also been dulled down a bit as I removed the ringing artefacts. Happy with the result for now though.

Replaced one of two potential flexure areas in the imaging train, tilt has moved from being diagonal (top right to bottom left) to just being at the top now. Looks like I will need to get a Precise Parts part made to remove it. OR it is slight tilt in the sensor as it feels stiff at the moment.
