Hi Philip,

All are very nice. I like the enlarged Trifid the best.

Hi 5ash or philp, i found out a long time ago, get the system guiding or autoguiding. The potential is there. You will find even the 'good' images are better. Meanwhile you are getting much better at squeezing out the detail.

Nice shots there. Yes guiding (auto or manual) is the go. That said, thats pretty good going for no guiding. My mount has slow (and controllable) perioding error that doesnt allow unguided shots that long. They have to be guided.
