Details:
Here is Comet C/2022 E3 (ZTF) from tonight. It was finally clear with no moon! This is a mono image (sorry, not color). I used my Takahashi Epsilon 180 ED @ f/2.8 and ST10 XME camera. That's a 21 year old camera and a 21 year old laptop used for imaging! The comet is moving pretty fast, so I could not stack separate subframes on the stars or the comet would blur.
Anyway, I attached a single 45-second image presented normally and an inverted image composed of 25 individual 45-sec exposures stacked on the comet head with stars streaking. I did an STD-combine, and that tamped down the star trails a little. It did bring out some streaks in the ion tail. I wish I could combine on the comet and combine on the stars separately, and then recomposite. I've tried a lot of ways over the years with no success.
The comet was only about 4 degrees south of Mars this evening.
