C/2013 A1 (Siding Spring) is dealt with in detail here.

C/2014 E2 (Jacques) continues to put on a nice display while continuing to fade. The comet is now around magnitude 11. The ion tail is gone but there is still a nice well developed coma.
The comet is now well visible from the northern and SSO scopes as it passes through Aquila, although still best from the northern scopes, where it can be imaged for most of the night. C/2014E2 has only a couple of nice encounters this month.
The comet passes 9' from the open cluster NGC 6756 (mag 11) on October 15. Then on October 28-30 the comet is less than 45' from the globular cluster NGC 6760 (Mag 9)

Comet C/2012 K1 PanSTARRS from SSO during October. The large rectangle is the field of view of T12. Click to embiggen and print.
Comet C/2012 K1 PanSTARRS is now high enough in the southern morning skies to image. It currently is showing a great double tail. Currently magnitude 6.9, it is brightening slowly towards a predicted maximum of around 6 late this month.
The comet passes through Puppis, coming close to a number of nice clusters.
On October 14-15 the comet is one degree from NGC 2482 a mag 7.3 open cluster. On the 16th it passes 10' from the open cluster Tr9 (mag 8.2).
On the 17th it is within T12 distance of a number of open clusters, including NGC 2483 (mag 7.6) and NGC 2453 (mag 8.3). On the 21st the comet is within 2 degrees of Cr 132 and Cr 140 (Magnitude 3.5).
On the 23rd the comet is at the edge of Cr 139. This will be a difficult shot as the open cluster is very bright (magnitude 2.1) and care is needed to make sure the stars don't over expose while imaging the fainter comet.

Comet C/2013 V5 (Oukaimeden) has emerged from the evening twilight and is now accessible to the SSO scopes. However, it is a race between the rising comet and the rising twilight. By around mid October the comet will once again be too low for the SSO scopes at astronomical twilight.
The comet is currently around magnitude 7 in Hydrus, heading for Libra and Saturn.
On October 1 it is 39' from the globular cluster NGC 5694 (mag 10.2). On October 11 it is 9' from the globular cluster NGC 5897 (magnitude 8.4).

C/2012 X1 LINEAR is around magnitude 12, and fading slowly. Visible in the evening to early morning sky for the SSO scopes, it moves through Indus with no interesting encounters.

On October 4 39 Laetita is 0.5 degrees from the NGC6455, and on October 5 Ceres is 0.4 degrees from Saturn.
