20060722 Home@Walnut M4 again

Transparency is quite good again, so tried to capture M4 again with longer exposure at 18.1s each frame, low gain at 300 at first and then ~350.

Total 110 frames captured lasted for 33.12 minutes.

Redo using registax with its derotation function:-

Both the M4 and NGC 6144 is more resolved and well defined.
