Hi All,
While watching the Olympics, I browsed through Mike's excellent Planetary processing guide again and realised that I have been missing the important "stack limit" section. DOH!.
I ran two images through registax again that I took on 16th May and 5th August respectively and it turns out I
can capture moons after all!

and that was with the Pentax digital camera too! Its interesting to compare the Pentax on the left with the 2.5x barlow and the one on the right taken with the 3x ED barlow and prime focus with the ToUcam. hmmm, noiiiiice!
Gotta be happy with that eh? Seems this does a lot for the quality and I feel a bit silly for missing it out all this time, oh well, RTFM right?
Thanks for stopping by and taking a squiz! (PS. before you ask, there is no moon in the second pic

)
Cheers
Chris
