Every year I like to make a pilgrimage to the frozen outlands of the solar system to grab a set of images of Pluto to pay homage to Clyde Tombaugh who discovered Pluto while working at the Lowell Observatory near Flagstaff, Arizona, in 1930. Over the years I have done this with a variety of telescopes including my little ETX-60. This year I was curious whether it could be one my with my Seestar S50 in part because I’d like to use my Seestars for observing asteroids. As it turned out, the S50 worked quite well! This image combines 4 fields showing the position of Pluto on the evenings of 9/27, 9/28, 9/29 and 9/30/2025 at about 10:00 EDT. Each field was approximately 30m x 10s images taken using the Seestar stargazing mode. If you look closely near the center of this image you can see 4 ‘stars’ evenly spaced in a nearly straight line. That’s Pluto as it moved from left to right over the 4 nights of this series. When these images were taken Pluto was 3.2 billion miles distant in the constellation of Capricornus shining at magnitude 14.5.
