Whirlpool Galaxy, STL, 6/13/2026

Not a hike. I was out here on June 13, 2026, for my second consecutive week of outreach, but did not manage a hike on either trip. This week, like last week, was very windy during set up, but because the winds died down last week, I went ahead and set up my big refactor for astrophotography. This is a single frame, 60 second exposure, ISO 5000, through my 152mm f/8 triplet with .7x focal reducer / field flatner, cropped, to eliminate vignetting. Took it as the public observing wound down, and I still had my big Dobsonian for public viewing while I did this. It's a good shot for me and my limited technique. But I also took a number of shorter exposures, which I may eventually learn how to stack and process for a better result.

No idea how many people pop over here to check for astrophotography, but I do post some of my shots here, albeit usually embedded in an accompanying hike. This one's a standalone, though. Wanted to shot M51 during the last season, but weather did not cooperate.

Galaxy season is drawing to a close, but there are still a few other objects that would be within range of my set up that I haven't shot for the summer season. We'll see how things go.
