Update on the sensor cleaning - 99% successful thankfully - there is one small blob left which is pretty easy to remove in Photoshop, but at some point I will probably do another cleaning run with the swabs and isopropyl alcohol and get rid of that too.
Last night was fairly clear so I did 3 hours of 30 second exposures on the Eastern Veil Nebula with the Askar 71F / ZWO 585 MC Air combo and got this:

No issues at all with the wifi BTW so that problem seems to be sorted thank goodness. I got ambitious and set the scope to shoot another target after the Eastern Veil but my Ecoflow power bank ran flat after 20 mins and shut everything down… 
i shall have to use my bigger Ecoflow box if I do any more all-night sessions.
ETA: this was shot through a narrowband filter which cuts light pollution and emphasises the hydrogen (red) and oxygen (blue-green) emissions.
