What have we here in IC2948

[Nico13]

Still learning my recent purchase of a QSI 583 RGB camera was shooting the core of the running Chicken and had left it running over night and set to park at dawn.
Checking the last two frames after breakfast I found this.
Blink these two frames and you will see some intruders have snuck into the last frame saved at 5:00AM this 8 min Lum sub shows what appear to Asteroids streaking across from the bottom in a curved path.
The brighter two actually show dusty trails showing the curve.
Details are
QSI 583 WSG
300 sec Red sub 1x1
420 sec Lum sub 1x1

Ken, MPEC gives me no known minor planets or comets in the area around the brightest of your marked objects (11:39:56.54 -63:23:35.5) assuming the time is about 2012 12 19.75 UTC. If you've got a better time I'll give it another go.

Andrew, it was 5:01 am AEST daylight saving time so 19:01 UTC on the 18th.
Pretty unusual and yes comet like as they did leave a tail like trail on the brighter ones but pointing in the wrong direction, somewhere between 90 and 180 deg out and so many of them together.

Ken, the only object that shows up in MPCChecker http://www.minorplanetcenter.net/cgi-bin/checkmp.cgi is C/2010 F1 (Boattini) which is moving south at 11 arcsec/hour. That's more than a degree from the coords I derived from astrometry.net and hence covers your entire FOV.

Thanks Andrew I've never had to check anything like this before so your help is appreciated.
I have plotted the comets path in Sky Safari and it is definitely in the right location, see the image below.
Problem is as you say it's travelling South and as we can see from the field of view of my image, the inner field is the RC8 by the way, the objects were travelling East to West and at about 1 deg an hr as my field is 30 arc secs top to bottom and that's an 8 min sub so about six times faster give or take.

This is a better look at the trails they left in the image, reminds me of the flickering tail of comet Lovejoy when it grazed the sun. This one is the brighter in the lower centre.

[mithrandir]

That looks more like a meteor trail being broken up by high altitude winds with the meteor finally exploding.

Looks to me like the camera/mount has moved and you posisbly have a brief image or a bright star that has momentarily appeared in the field of view. That wobbly trail in the bright star is a classic sign of mechanical rather than astronomical movement. Just a guess.. weirder things have happened..
