Rick,
Thanks for the prompt I have just done some digging on the new version of PixInsight and I might be renewing my licence. It has been year or so since I gave it a run and I see the the two main crashing and slow downs I experienced on OSX seem to have been addressed.
Sorry John for hi jacking the thread a bit off topic but maybe it has helped my setup improve as well thanks all.
I totally agree on the para-focal claims though I have used Meade, Orion, Baader and lastly Astronomik filters which have all been "para-focal" and whilst close to the same focal change they are not quite equal even on the f10 systems at work.
Justin
