Thanks Mike and Glen.

Field of view in the crop would be close to 60 arc min.
Once I stack them I think the ion tail shall be easily visible to the edge of the frame..
cheers Gary

As listed on comets-ml, they have been able to image a dust tail.

Comet Boattini was 50' below sigma Ari this morning. The comet is about 5' in diameter and fainter than magnitude 8. It was easy to see in 20x80 binoculars but difficult with 7x50s. M33 was brighter and larger than the comet in 7x50s.

I saw the comet again this morning with the 12" Dob. Yesterday there was moon and haze, today was much better. The diameter was about 5' and it was easy to see in the 50mm finder.
