Hi there, I also tried to shoot and process this comet (C2022 E3) earlier this week, let me tell you what I did this week, hoping it can help you. 🙂
First of all, an excellent dark environment is necessary. The comet is not bright enough to get a good image in the center of the city. So we drove to an island far from Suzhou's center.
I used an ASI2400MC with a duo-band filter, the telescope was Askar 107PHQ. The entire system was mounted on AM5 so we have no reason to bring a counterweight up to the hill.
Then we do the same things as DSO imaging, like polar alignment and Autofocus, with ASIAIR.
In the third, selected C2022 E3 from ASIAIR's list of comets and tapped"GOTO".
Suppose the comet didn't appear on the screen. In that case, a method is to check the newest location of the comet in software like Stellarium+ and then enter the comet's location into ASIAIR, it might be a little bit tricky, but it's useful.
After the comet shows up on the screen, turn to the operation interface of guiding, manually select the comet's nucleus as the main guiding star, then it's time to start the exposure.
The parameter I'm using is 60 seconds for every pic, and the gain is 0, but the fog around the island and wind(it's sooooo cold 🙁 ) only gives us about half an hour to exposure, so I only have a short video. (at the back of this article)
When I started working on the images the next day, I tried SiriL and ASIStudio to pre-process them and PIPP to compose them into a video.
For ASIStudio: drag your image into ASIDeepStack, and make the DBF calibration files as DSO processing usually did. Then you need to load the calibration files to ASIFitsView and open the directory where you save your Light files, right-click on the image, and select "save as" for each Light file.
Finally, you'll get a series of pre-processed Light files.
For SiriL: copy your image to the specified directory, then run the pre-processing script ( about the usage of SiriL, there is a large number of posts and blogs on Cloudy Nights or similar sites). Wait until the script finishes its work, and then open the directory of pre-processed Light files.
After you have a series of pre-processed Light files, drag them into PIPP, and follow the images below.
There we go! Here is my result after those work. (been compressed)
Hope you can get your video soon. 😉
