90 degree pass. Recorded with a modified SDC-435 and 8" LX200 @ f/10. 1/500 sec exposure (no AGC). Tracked with Satellite Tracker by Brent Boshart. Would have shot at f/20, but had trouble with the viewfinder alignment. ... https://www.youtube.com/watch?v=8E6bQcvT9W4
All times are actually UT -7, not UT. Taken with the T4 telescope on the itelescope.net network in visible as well as infrared light.

It seems that a small firestorm has erupted on the internet in the last few days over a time lapse video of an asteroid that narrowly missed a collision with earth. In this particular video a tiny "mysterious object" can be seen dancing to the left and right while simultaneously moving upwards in the frame, and it appears to move out of the way of the asteroid in the animation. This is caused by a hot pixel. Normally hot pixels are stationary from image to image, but when you realign your images to put them together into a time lapse where the stars remain stationary the hot pixel can appear to "move." It's actually tracing out the original motion of the telescope. I'm showing this video as a comparison from my 2-7-09 Lulin animation's red channel where there was a hot pixel near the top of the frame. The first segment shows the full frame, the second segment shows a zoomed in crop of the dancing hot pixel.

On Sunday 1/15/23 at 5:56 pm local time, a SpaceX Falcon Heavy launched a mission for the Space Force, USSF-67. I was able to track one of the boosters from launch at LC-39A to landing at LZ-1. This was filmed with an 11" Celestron NexStar GPS using a Blackmagic Pocket Cinema 4K camera at an effective equivalent focal length of 5.6 meters.
This used a new, experimental version of my RocketTraker software, adaptively looking through the trajectory prediction published by FlightClub.io and seeking the closest point in the trajectory file based on the rocket's observed position and time. This allowed for greater tolerance of deviations from the expected timing of the booster landing and allowed me to follow it all the way down. This new version of RocketTraker will be published soon on my community page exclusively for channel members!
