Taken with filters as it was late and I would have had to refocus after manually changing them. The field of view is 94 x 71 arcmins. The 3rd photo was taken on the 28th February at a mean time of 22:04 with the 16". You can see that the comet pretty much fills the field of view of 10 x 8 arcmins. |
