I was 0.1' out on RA and 0.0' on the Dec with all my measurements.

This is the first time I've managed to get the comet too and I've been
trying since 11 May!  Most of my data up until now has had the comet some
way off from the predicted position and neither myself nor an experienced
astronomer could be sure of it in any data I had between 11 May and 9 July
and that was using some big aperture scopes.  I'm obviously pleased I
nabbed it now.  What altitude was it when you imaged on 11th?

Kind regards
Wendy Clark
