These 2 images have been stacked , opened in Startools and auto stretched with just a bin , crop and a basic wipe ( no processing )
M8 Lagoon was capture a month or so ago on a similar night , same set up , 50% Waxing moon , 180 sec subs , similar integration but using Gain 100 or lowest read noise
M16 from last night using Gain 0 highest dynamic range 180 sec subs
By the way compare files sizes after saving as jpegs to upload
M8 805KB
M16 1.98MB ( 50% more noise ) I’ve had to reduce this image file size to load it into IIS
I’m going to have to image M16 again using Gain 100 lowest read noise and same subs etc…., but the moon won’t be the same week after next , heading into the new moon period ( crap weather for the next 8 days ) It’s not going to be a fair comparison
I’ve never had such a noisy image from my 2600MC
Comments welcome

Looks like ice on the sensor, maybe remove and recharge the desiccant
Also try the suspect cable inside. but I reckon icy sensor
