ISS Solar Transit (Jason dain)

ISS Solar Transit

While doing astrophotography, I often see the International Space Station (ISS) flying over. I did some research on how to photograph it using various methods and found that it is easiest during a lunar or solar transit. Using a website called Transit Finder ([url=https://l.facebook.com/l.php?u=http%3A%2F%2Ftransit-finder.com%2F%3Ffbclid%3DIwAR1lyfZV07FiuxX79eQdIPXnSUVzJqU-fY_8tiQrkBNVwPGRjLN8gVtS_zM&h=AT2wOBKKGabokddGnAvA19NTqU3lxJ5Bz5I0xRFFpIDkH7PJd-074sqwx9rE7hoKfl0wjd4o3kopAZxI5Qvhvcks_fNzjuxWIwOmGRHnCsmha4y5C_zg9dffhevQ4UcJownz&__tn__=-UK-R&c[0]=AT3H0ho0zDNghVW-1nQzTnvt06o2xqMQuNUay0kLXcvG7aiXyjiOIBFpacfl0EvDRvb6q60ItM4wx8hFkhhxr2iz5s32sOhaStxjtZ7we1uAiatWxHLQWYmCh9TtpCvRM0C1u4wI-u39xXc02ShdUhQGWQ]http://transit-finder.com[/url]) you can get very precise details of where and when you can catch the ISS transiting the sun or the moon.
Today, just after noon was one of those times when it would be visible relatively close to home so I grabbed my solar filter, camera and tripod and off I went. I setup at a spot right on the centre line of the transit and using a calibrated timer (http://time.gov) prepared for the transit. I gauged how quickly the sun would move across my field of view and then decided when I needed to move into position. I set my camera to record video at 4K, 30 FPS where each frame was at 1/3200th of a second, f/9 and ISO400. I used my Nikon D500, tc14iiie teleconverter and 500mm f/4 lens for the job. I started my video and let it run and watched in amazement as the ISS flew by in about 3/4 of a second.
Using PIPP processing software, I extracted and aligned the 22 frames that had the ISS in them and exported them. I then loaded them into Photoshop, selected all of the images and used Darken mode to create the stack. I then applied some coloration, noise reduction and contrast adjustments to get the result you see here. Next target is the ISS passing the full moon!

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.
