| Comment : |
With a magnitude of 18 or less it's very difficult to find the comet.
Needs a long exposure time and a very dark place to succeed.
Then the comet can't be find it's not possible to aligned to it.
In this case it doesn't matter because it moves very slowly so it can be aligned on the stars instead.
But the two bright stars could help to find the place where the comet is.

With help of the two bright stars and the galaxy NGC 5164, magnitude 14.6.

| Comment : |
With the CdC (Skychart) software you can simulate and see where to find the comet.
The inner red circle is 1 degree diameter, the outer is 4 degrees.
The rectangle is the field with a full frame sensor at focal length of 910 mm, about 2.2 x 1.5 degrees. |
