very nice.

Did you use an IR block? Apparently they can help with bloating of the brighter stars. Looking at it I don't think your focus is out as the dimmer stars are good and crisp.

Yes the IR Block should help, I'm trying to get to grips with the guider and then the focal reducer, next time I will add the filters.
