Ok, more like 696x8s, but all the same.
Because I wasn't guiding I set up SGP with several targets, though they were all M8. I do this because I can then set it to center the target at the beginning of each "target" this keeping M8 fairly well positioned throughout the night, even though I wasn't guiding. Unfortunately for me, I stuffed up in all but two of the targets, and set it to finish entire events, rather than cycling through the different events, resulting in getting a crapload of luminance and red subs, but bugger all blue or green.
I've basically spent all day since about 8:30am weighting, registering and stacking these subs. Unless you've got a super-computer, I do not recommend it. For those wondering why I did it, I had a choice between guiding and using my flattener, so I used the flattener and did very short subs.
Anyway, I think it's an ok result, especially for 8s subs. Sub count was:
L = 388
R = 262
G = 24
B = 22
Image was cropped because I preferred the composition like this. Full version (same crop) on
