Description

This is my third image of the Comet C/2022 E3 (ZTF).  I am including this one because the orientation continues to change and in this particular case, it appears that the tail of the comet appears to be quite a bit wider and maybe showing a split (though not very obvious).

I used a 92mm APO refractor with reducer yielding a focal length of 488mm.  The camera was a full frame (35mm) sensor in a cooled astro camera.  I decided to reduce the exposure lengths to 30 seconds and captured a total of 181 useable frames with the ZWO ASI6200MC camera.

I again used the CometAlignment Process in PixInsight to process a stars-aligned image, then generate a comet aligned set of images from the Debayered stars-aligned versions, integrated the comet aligned images while simultaneously subtracting the starfield (identified as the 'operand' in the CometAlignment process).  I used the CloneStamp to remove the larger star residuals in the comet only image and then added back the starfield.

Continue to be interested at the way the comet continues to morph in brightness, orientation, and nature of the tail.
