Wondering if I can pick the collective brains..

I recently purchased a GSO RC8 and its basically the first time I have had to do any colimation, so not sure what to expect.

I was out tonight testing out a new focuser upgrade and rebalancing after some setup changes and did a couple of tests.

I checked collimation and indications are its pretty close (image uploaded, if its way off please shout out) but when I did a capture, I noticed the stars are seriously soft, though they do look focused. They look like stars all across the field of view.(bit of a first that..)

I did a slew back to my focus star at the zenith and double checked focus and all seemed ok with a Batimov mask.

Popped out of the obsy for a break and realised theres a lot of seriously warm air blowing about out there tonight so wondering if the seeing is totally messed up and this is the first time I have seen the impact or is it possible I have other colimation related issues.

Images were taken 2 to 2,5 hours after the roof was rolled off and cool down started so tube should have been ok?

Any guidance appreciated. Am hoping its just seeing related.

Many thanks
