Here is how comet C/2022 E3 ZTF appears this evening in my imaging rig
(100mm f/5.8 refractor). I used the PHD2 tracking software to track on the
head of the comet.

I use a black-and-white imaging camera (ZWO 183MM PRO) in combination with
the associated luminance, red, green and blue (LRGB) filter set. I captured
one 60-second frame per filter. The composite color image was generated in
PixInsight, making use of the CometAlignment process tool. The comet is
really zipping along, which is why the individual stars are separated out
into the distinct color filters. The comet, itself, came out nicely green.

Enjoy,

-Gary

And here is a 50 minute total exposure obtained from a series of 1-minute
exposures using just the luminance filter.

Great captures Gary! I had a couple nights on the comet from my patio this
past week, but I expect my local light pollution kept me from getting the
ion tail.

Nevertheless, here is a short video of my images:

I processed each image through PixInsight's StarXTerminator process tool,
then re-integrated to better show the structure
in the comet's ion tail.

Nice image, Gary.
Here is a YouTube link I just got from the PixInsight team. It shows the comet's movement over a nine day period from late January to early Feb.
