Thanks John! They're a great little unit.

Yes a crop would be interesting. It is sometimes hard to tell which is tracking errors and which is coma when so widefield. The outer edges of my 30 second 14mm images show greater trailing as well compared to centre (which is usually further away from the SCP).
