I'm not worried at all

...naah, I think it's funny actually, many think an image has to be prefect before posting and then those commenting often feel comments must be solely about pointing out what they think is wrong with an image

...all's good and I agree with your comments..although it's not so much a registration issue as the tiny Ha stars in the AG12 data were hard to match 100% with the corespondingly larger blue stars in the Starfire data so there are some residule blue halos...they don't seem to bother me as much as others

, actually someone commented on blue halos in Rich Bowdens latest image and quite frankly I thought they were mad
Oh ye I meant to add, Tom Davis told me it would be hard to register wide field frames using the 16803 chip and the AG12 100% evrytime, so I was prepaired
