Thanks for responding so quickly Nick.

My magnitude estimate at 14th is based on a jpeg and furthermore there is a field star in amongst the coma so I am willing to believe it could in fact be nearer to mag 16. The jpeg tends enhances the coma contribution by stretching the fainter end of the image. Until I can get my hands on the FITS frames I am stuck.

The image you sent me separately just includes the location the comet was at when the FTN images were secured and where the field star is located.

Can you do an fwhm on your comet image?

Richard
