To be honest I was staggered with what it looks like for a one hour image. Obviously F4 accumulates data fast, but the ASI294 is noisier than the ASI2600 that will be going on it and the result is a lot cleaner than I expected for only 13 subs, the star colours in particular surprised me, the 294 never produced star colours as good as the 2600 did so hopefully the 2600 is a step up again. I am in a mad scramble now to sort cabling out properly and hopefully have another go at the same target with the 2600 next new moon. It looks like a lot of targets with the OSC won't need more than 5 minute subs so with luck, one good night might produce really nice images.
I am not sure if the F4 reduces spike length or not, this one has a pretty chunky spider for the secondary so that may influence things as well.
