This is a photo of three comets: C/2020 F3 (NEOWISE), C/2019 U6 (Lemmon), and C/2017 T2 (PANSTARRS). Here's the story of how this photo came to be...
I received an interesting question from my neighbor regarding Comet C/2020 F3 (NEOWISE) and a Meteor after I posted it to Flickr four weeks ago: Have you ever seen two comets in the same photo?
I couldn't remember ever seeing a photo like this, but I filed the idea away. Interestingliny, when Comet NEOWISE came up in conversation with some astronomy friends over the weekend, someone mentioned that another comet might be close enough to it to capture in the same frame. I checked Stellarium and found not just one nearby comet, but two comets that could be captured in the same frame with NEOWISE.
I also noted that the comets were spread out over about a 10 degree span, and that I would be able to contain them within a single frame using my Canon EOS 60Da with a 55mm lens. I had the great fortune to be able to use Arcturus and Muphrid in Bootes to help get my camera on target.
Getting the image that I wanted required that I stretch my processing skills, but somehow I managed. Not only was I able to see the two dim comets, I cross checked against Stellarium to verify that the two green blobs were indeed Lemmon and PANSTARRS.
That same Saturday evening one of Howard Astronomical League's dark observing sites was opened for its members, and I went out on my first attempt to image the three comets. I set up with my camera mounted on a Omegon LX2 Mini (mechanical wind up) tracker. I had not used this device for some time, so I found myself fumbling with it way too long. By the time I was polar aligned, had the target framed, and decided on the exposure, I was exactly one hour later than I had hoped to start imaging. By then the comets were very low, and ground fog had started to appear. I did not have a dew heater for the camera lens, so it was completely overwhelmed by moisture.
I could see NEOWISE in my unprocessed images on my dewy laptop screen, and I was able to verify that I was capturing the star field that contained the other two comets. Even though I could not see the comets in these images, I was hopeful that I would be able to pull them out in post-processing. But try as I might in the clear light of day, I got nuthin!
Amazingly, we had another lucky break in the clouds, and the site was opened again on Sunday night. I added a battery and dew heater to my pack up, and headed out again. Equally as important, I spent some time reacquainting myself with the tracker in the clear light of day. It was another very moist evening, but not nearly as challenging at the night before. I was able get up and running to start shooting sub-frames as soon as it was dark enough, and I could see that my data quality was much higher than the first time out. I couldn't see the other two comets, but I saw enough stars that I was pretty sure that I could pull the other two comets out in post processing.
Besides the obvious breakthrough in capturing three comets in the same image, this is the first time that I have produced a star field any where close to as rich and star-filled as this one. My second place effort doesn't even come close. I must add that I am pretty impressed with the tracker. Of 50 sub-frames that I shot, I threw away only one for a tracking issue. Not bad for a low-tech wind up device?!! I'll be sure to set this device up again before I forget how to use it.
Canon EOS 60Da with 50mm lens at f/2.8, and mounted on a Omegon LX2 Mini Tracker. Twenty minutes total integration time in 47 x 25 second light frames (nearly 20 minutes total integration time). Calibration frames consisted of 25 dark frames, 25 flat frames, and 25 flat dark frames. Light frames and calibration frames were stacked in Deep Sky Stacker, and post-processing was done in Photoshop.

Rolleiflex 3.5C and expired ORWO Color negative NC-19 roll film (1980'-90's ?), shot this at 20 iso then developed in the correct ORWO color C5168 processing kit, the chemicals expiry date was 13/11/90 but still seemed to work
Same wedding, same flower girls, this time on the beach for their photoshoot. The East wind was wreaking havoc with dresses and hair but this only pleased me because of the degree of spontaneity it brought to the images. Look at these little women, all of them beautiful and all adding to the zest and wonder of marriage. And all very busy doing their assigned jobs.

Though I prefer to use masks, I finally edited my brush for this by making a brush and using it with the eraser tool.
GIMP has a tool called the Paths Tool, which is like the Pen Tool in Adobe. I used it to create the brush used in this pattern.
Masking is easy; clipping masks are rather confusing. Just what I need to keep my mind occupied : )

Spotted this silver Flying Spur on the Lisburn Road today, the owners had a Navy one exactly the same, strange decision.
