The first Quarter Moon is Thursday March 1, the Full Moon is March 8 and the lst quarter Moon is March 15. While the Moon is a great hindrance to many of us imagers (especially the comet folks), the narrow band folks have a lot better time of it.
Comet C/2009 P1 Garradd has been delighting us for quite some time now, its encounter with the globular cluster M92 producing some outstanding images. Rolando Ligustri has been following the comets evolution with terrific results.
Garradd will bring us more delights, on the 25-26th it will be close to magnitude 11 NGC 6015, then on February 29 it will be close to magnitude 12 NGC 5949. Currently magnitude 6.6, it doesn't dip below 7 for the rest of March. Garradd is a moorning comet for February and most of March, so you need to be imaging from 2 am on.

The stand out encounter will be in early March, when the comet moves across the face of the Ursa Minor Dwarf. On Mar 02 at 12:55 UT the comet will be 0° 09' from the galaxy centre. Great compositions will be had before and after then of course. As always the latest elements for C/2009 P1 Garradd are from the MPEC.
After this it's quiet for a while (although the comet is a marvellous target by itself). Then on March 13 the comet is 45' from the magnitude 10 galaxy NGC 4236-1, although the Moon is still before first quarter, the comet is now rising early enough for good imaging to be had before Moon rise.
UPDATED: On 20-21 21-22 March the comet is within T14 distance of the 10th magnitude galaxy Coddington's Nebula (IC 2574). On 21-22 March it is also within T20 distance of the globular cluster NGC 3231.
There are quite a few evening comets, but they are very difficult. Comet 21P is too low at astronomical twilight for the iTelescope scopes. C/2012 C2 Bruenjes has faded considerably, it appears it was discovered at outburst, and is now below magnitide 17. It will also be below the tracking range of iTelescope scopes. C/2010 G2 Hill is roughly magnitude 13, but will quickly go below the tracking range of all scopes except T11 at astronomical twilight in early March.
Comet P/2012 A3 SOHO is now quite difficult, being below magnitude 14, but is is getting respectably high in the sky. On March 21 it is almost on top of the bright nebula vdB37, so some deep imaging would be nice.
Comet 78P Gehrels is between magnitudes 11 and 12, and has some interesting encounters. Between March 25-27 it is wwithing T14 range of Jupiter (although the proximity of the Moon on the 26th rules out imaging). The contrasts in brightness means that good shots are improbable unless you do mosaics.

On March 3 it is 31' from NGC 990 (magnitude 12.5), then on 10 March it is 1' from magnitude 14 NGC 1117A, on 11 March it is 19' from magnitude 112 NGC 1134 and 5' from magnitude 14 NGC 1127. Deep sky imaging scopes (T11, T5, T4 etc.) should be good for these encounters.
The supernova in NGC 3239 is still bright and worth imaging in the deep sky scopes (someday soon I'll publish my light curve).
