Can we get enough of E3 ZTF? I guess not 😊
After previous two attempts on Jan 20 and Jan 26 which came out nice, I wanted to capture some images on Feb 1 for obvious reasons. Moon and clouds gave me a break on Jan 31 for one hour around 4am. I was waiting several miles away from my house under Bortle 4 with my rig. It was a work weeknight too.
I could only get 1 hour of data before cloud rolled back in and then it was dawn.
Post processing was a big challenge. There were very strong star streaks in stacked comet image from DSS so I was forced to learn comet stacking in PI. Not much different result from PI as well. May be it was because I took 2min exposures and the comet was moving pretty fast. I then took a different route. I removed stars from all cometaligned images and cleaned them up by hand using clone stamp because both StarXterminator and StarNet+ left many stars in. Then I integrated those clean images, did usual noise reduction, stretching and some curves. After that I added stars from the star master light. Here is the result. I hope you will like it.Skywatcher Esprit 100ed

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.
Dismissals 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.
