Thanks for the explanation, Ray. If you ever feel like writing up an in-depth article about your newt mods one day, you'll have at least one very interested reader
Ray, do you use weights/etc to counter balance the focuser-end weight??

Used to be a pig of a scope to get/keep aligned, but is now very stable. The RCC1+filter wheel+OAG+SXcamera weighs just a little over 1kg, which helps. There is a tiny bit of astigmatism that focuses out to smaller than the average seeing disk, but the system may be able to do slightly better when this little niggle is resolved (probably the main mirror mounting). Not currently willing to waste a night chasing it down though, since cloud free darkness is very hard to find lately.

Will write up what was done and post it in the astrophotography equipment forum in the next few days. Thanks for the interest. Regards ray
thanks for the feedback Robin. Agree that the core is less yellow than is generally accepted. Others have commented on the colour (Mike and John suggested more colour, Greg more yellow, Jase more blue). I am in the process of trying to work out exactly how PixInsight handles colour with the aim of developing a set of procedures that produces results nearer to the mean of available images.
