Very nice image John. Heaps of sharp detail but just a little on the green side.
As for Reg6, not over joyed with it. It removes a lot of controls that I like and the mapping is no better than any other registax since it was introduced. Besides I worked out a long time ago how to get seamless images with mapping in earlier versions of registax. Also not keen on the removal of the reference frame feature. I found it useful but it was removed because others thought it was not. In general it seems like reg6 is designed to do automatic stacking without any control over what goes into the stack. I will not be using it until proven it is superior to reg5. Personal opinion really.
Well done again John on getting some nice data again.
