Comet Lemmon, tail still disrupted.
Hi,
Here's my image for tonight, 08/02/2013.
Comet Lemmon's tail is still disrupted, fascinating following it's changing shape.
I used the 8" astrograph to get a little fainter, and I used some minimum pass filter in PS to make the tail stand out more.
Cheers,
Justin.

Nice shot Justin, what were your camera settings? Exposure settings etc...

Thanks Andrew!
Sorry forgot that.
ISO 1600 - 10 x 150 sec subs.
8" astrograph - Heq Pro 5 mount - baader coma corractor - unmodded canon 1100D - cooler box.
Stacked in DSS median - stars and comets - processed in PS7.
Also just updated the image.
Cheers,
Justin

Stunning image Justin,
Great composition too, the 2 stars near the coma add a nice reference.
Seems like the 8'' does a better job at picking up that faint tail.
I can definately still see that knot like concentration. I wonder if this has been observed visually, its probably far too faint though.
Your gathering a very nice collection of images even before the comet has reached full brightness, I am eagerly awaiting your next set of images.
Cheers

Thanks Orestis!
Might have a try with the 16" visually tonight, should have reasonable chance.
Cheers,
Justin.

Great shot.
Comets often have 2 tails. One is the water vapour/carbon dioxide trail the other an ion trail which blows from the solar wind which may be at a different angle to the tractory of the comet.

Thanks for the info Justin. I noticed you have little egg stars also, must be difficult tracking near the pole.

Yep, a but of a bugger around the pole!
Didn't have time to use the auto guider on this one, unexpected guests turned up. I used it on the previous image with the ED80 and it worked well. Needed to aquire on achenar, then swing back the comet.
Cheers,
Justin.

Nice image Justin
. The stars and comet alignment option in DSS appears to have worked well for you in this case.

Thats a ripper Justin, nicely composed and well executed
Fits nicely in the field of the 8" at the moment ! Wonder how long that tail is going to grow over the coming weeks, will be interesting !
Good stuff !
