C/2013 R1 Lovejoy and C/2012 X1 LINEAR over the next few weeks as seen from Mayhill NM. The rectangles represent the field of view of T14.
On 6 February (06:08 UT) comets C/2013 R1 Lovejoy and C/2012 X1 LINEAR will be in conjunction in longitude with a separation of 2° 09' 13". On 7 February (01:24 UT) they will be closest together at 2° 06' 51".
The comets are around magnitude 11, and are currently near 72 Oph (Lovejoy) and magnitude 4.2 IC 4665 (LINEAR). They can be captured in a mosaic using T12, with careful postioning of the image centres. See this zooamble example from Jahn Jost.
Over the next week the comets will draw closer together, by around 2 Febrauary both comets will (just) be in the same T14 frame, of course being best on 6-7 February.
Stacks of 120 sec exposures should work well. Howevere the pair are only 29°-30° above the horizon at astronomical twilight in the morning, just above the 25° limit of T14, so exposure time is limited.
