C/2022 E3 (ZTF) (Rupesh Varghese)

C/2022 E3 (ZTF)

This was my take on the Comet C/2022 E3 (ZTF). This is one of the times when I wish I had less focal length to get it's incredibly long tail. It's about 2 hours and 4 minutes. I have 61 frames of LRGB each at 30 seconds each. This was done under Bortle 7 skies so I want more time, but it rose late and the sun came up quick

This was kind of complicated to process. It could be from my lack of processing knowledge, but I think I made it work.

I used WBPP to calibrate, register and integrate the images.
I have LRGB masters which show the stars all aligned, but has a trailing comet.
Then I took the registered images, and then used comet alignment for each of the filters. This is where I did what I think was the only way I could get the comet to work. I did a batch processing of all the comet aligned pictures in StarXterminator to remove the stars and leave me with individual starless images of the comet.
I then integrated the starless images to get the LRGB masters for the comet
I then proceeded to process the Comet as any other target with the following steps

DBE
PixelMath to combine RGB
SPCC
NoiseXTerminator
EZ STF
Curves Transformation
LRGB Combination
HDRMT

I still had the original integrated images with the stars and did most of the same steps as above. I also did BlurXTerminator to get a bit sharper stars as well.
I stretched the image and then removed the stars using StarXTerminator.
I then did PixelMath to merge the Stars and the Starless Comet image together to get the above image.

I hope it makes sense.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
