I cannot see anything/much on the left hands side, or the right either.
Green is usually amp glow, and for whatever reason on one side or the other.
Cause is the amps on the sensor chip. The pixel collects the light, effectively changes it over to an electrical charge and when output the amplifiers boost and maybe change the pixel signel. Say change as I recall reading it is something like currant collected to voltage out - maybe the other way round.
Each pixel has - I understand - it's own little amplifier. And simply they get warm and we get a signal.
There are CMOS sensors in the pipeline that reduce this, not sure if remove it is 100% accurate. Have a search for s-CMOS, and eventually someone will produce a very low currant amplifier on the devices, just not yet exactly. Although ZWO do a 533 (??) device that boasts zero amp glow.
Simon Todd has this on it but it reads more a 183 camera review or detail then amp glow.
Problem is I suspect caused by much in astrophotography -we are using sevices and items that are not specific to AP. Most sensors are for CCTV etc and so the collection period is maybe a few seconds and often less then a second. So amp glow is not a problem for those periods. We haowever want 30 seconds, 60 seconds and many want 600 seconds. The devices were not really intended for that usage, so produce "problems" when they are made to do it. Your DSLR was really intended for exposures of say 1/100 sec, not what I guess is 30 seconds.
