L4-Panstarrs is still god visible, but only for "early birds" - that hurts....
On 16th of April in the morning, 3 to 5 AM, the position of the comet was in Cassiopeia near Schedir.

Find the link to my Video of the comet L4-Panstarrs, captured in the morning until dawn in the garden

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

I took 222 exposures, each only 15 seconds.

Animation was created with PixInsight, videocapture with Camtasia Studio.

(Attention 70MB)

I was surprised to see with 15 second exposure a lot of the comets tails.



Find also the stacked Image, 152 x 15 seconds, used for the comet only and

10x15 seconds for the stars plus comet. All processing was done with PixcInsight, all stacking

of the comet was done with Process "CometAlignement" in PixInsight.



I think comets at that morning time are not healthy...

Still not recovered.

Excellent image and video Gerald,


Personally I'd like some more info on how you made the video with PixInsight thats something that I hadn't even considered before.


Thanks for sharing & regards

Hi Neil!

The creation of the comet video is/was very simple.

PixInsight has a process    "Blink".

This process runs an Animation of 2 or many more Images.


So i started blink, loaded the 152 Images into "blink" , used STF to stretch the images,

( Images in the Video are all linear unstretched and were made visible with STF),

Than you can browse in "blink" through the images either manually or you

select automatic run and the the speed - and the animation runs. 

In parallel i started the video recording feature of Camtasia Studio, selected

the part of the Screen i wanted to capture, (the PI window with the comet animation)

pressed start , ....  stop  and save and the video was saved in the Camtasia directory,

ready for use and distribution.


The title and end page was also created in PixInsight and afterwards integrated (pasted)

with Camtasia Studio into the Video.

Camtasia Studio is the software i also use to create my PixInsight Video Tutorials.
