Hi Lee, Thanks for the feedback mate. Yes I did notice the stars, I used to have some really bad focuser tilt at one stage and I spent about 3 hours one Saturday afternoon totally dismantling the focuser, secondary and the spiders. After re-assembly it was much better but still a small amount was apparent. I have been slowly adjusting it some more each session to hopefully eventually get rid of it. I also think it has something to do with deconvolution, as this process seems to make it worse. I have been playing with settings etc to try and eliminate it but as you know the learning curve is steep, I'll get there just takes time. My camera is a modded 1100D. Not cooled although this coming wet season I am hoping to do a peltier cooling mod on it.
