In this episode of The AstroGuy Podcast, Wayne sits down with planetary imager Greg Shanos, one of the most dedicated and skilled amateur astronomers working today. Greg recently completed an extraordinary observing project: imaging 15 out of 16 Titan transits across Saturn during this year’s rare transit season. These events only occur during brief windows every 15 years, making his achievement one of the most complete amateur records of the phenomenon.

Before the interview, Wayne reminds listeners about the 1,000-subscriber contest, where one lucky viewer will win a free autographed and numbered print. If you haven’t entered yet, be sure to visit the contest video and leave a comment before November 25th.

In the main segment, Greg shares how he planned and executed his transit campaign, the gear and imaging workflow he relied on, the challenges he faced along the way, and what these observations reveal about the Saturnian system. Greg was recently honored with the 2025 Walter A. Haas Observer Award from ALPO, recognizing his significant contributions to lunar and planetary observing.

This episode offers a deep look at the power and passion of amateur astronomy — and how one dedicated observer can produce scientifically meaningful work that stands alongside professional data.
