Hello!
Comet Lovejoy now is very good visible, but only for "early birds" - that hurts....
On 3rd of December in the morning, 5:15 to 7:15 AM UT, the position of the comet was in Bootes.

Find the link to the image of the comet Lovejoy, captured in the morning until dawn

here near Vienne in Ebreichsdorf Austria using my C14/Hyperstar with QHY8.

Click on the image in the link to see the larger version.

I took 112 exposures, each 40 seconds.
All processing was done with PixcInsight, all stacking
of the comet was done with Process "CometAlignement" in PixInsight.


Aloha

Hi Gerald,

That is a pretty amazing image of the comet Lovejoy! The core in the coma of the comet is clearly visible. Or is it a star on the background.

Thats a fantastic shot Gerald,

 

If the weather forcast holds, I should be able to hunt for it Wednesday morning this week, so I'm keeping my fingers crossed!!!

 

Thanks for the update.

 

Clear Skies

@ Will!

Yes, in the center of the coma the bright comet core is clearly visible. It is  NOT a backgroundstar...

Have a look at the fullsize version where not only the core is visible also the 2 eruptions in the front of the core.

 

@Neil

Thanks, i will  keep the fingers crossed for you too.

Very nice, Gerald!

 

Did you try the Larson-Sekanina filter on the image?  I'd be curious to see how it works with comets.  I used it very successfully to tease detail out of the solar corona but it was originally developed for comet processing.

 

Cheers,
Rick.

Hi RicK!

Yes, i tried Larson-Sekanina Filter, but my results were not satisfying, so i switched to HDR and LocalHistogramEqualization which gave more details in core and tail.
