The Running Man Nebula, one of my favorite deep sky objects. It fits in the same frame with the much brighter Orion Nebula. So it tends to be an afterthought and is rarely photographed and processed by itself. But of course, that's the best way to bring out the details. #Science #Astronomy

This is UGC 12613, also called the Pegasus Dwarf Galaxy. It's an irregular galaxy in the constellation Pegasus. It's small and very faint, so I used almost 17 hours of total exposure time to try to bring it out. #Science #Astronomy

This is NGC 6934, a small globular cluster in the constellation Delphinus. There was a lot of moon last night, so I wanted to stick with something that I thought had a chance of holding up under all that light. #Science #Astronomy

Right in the center of the frame is the globular cluster NGC 7006 in the constellation Delphinus. Its relative size is so small that it could be easily taken for a star unless you zoom in. #Science #Astronomy

The small (from here) globular cluster M30 in Capricornus. It doesn't get much over 30° above the horizon at my latitude, which doesn't help for clarity. #Science #Astronomy

I've also spent two nights working on M33, the Triangulum Galaxy. I wanted about 10 hours of it, but I ended up with a little less than 8 due to intermittent clouds. #Science #Astronomy

I added another 3 hours to this last night and processed it again, considering only the core of the galaxy and bringing out the supernova.#Science #Astronomy

This is a cropped version of the NGC 7331 image, just barely showing the supernova. At this focal length, it's pretty faint. #Science #Astronomy

catherinerhyde @catherinerhyde.newsmast.social.ap.brid.gy · 07/09/2026

I was able to add another 3 hours to this (NGC 7331 and Stephan's Quintet) last night, and I reprocessed it. I like this version better, if only because you can zoom in and make out the star in the center of the galaxy. The center is not as blown out. #Science #Astronomy

A spiral galaxy is centered among scattered stars and distant galaxies on a dark background in outer space.

The big galaxy here is NGC 7331, with several much smaller companion galaxies floating above it. Or appearing to, anyway. The galaxy cluster in the lower left is Stephan's Quintet. #Science #Astronomy

Here is another image from later, in the second half of the eclipse. Beyond that, I think they're all going to look pretty much the same. #Science #Astronomy

It was 95% cloudy when we arrived, 95% cloudy when we woke up, and almost perfect for the eclipse. This was the only cloud action we had during the eclipse. #Science #Astronomy

The full moon setting when we got up this morning. It was awfully nice of the clouds to clear out during the eclipse.

A not entirely successful (it's awfully noisy) image of the comet 10P/Tempel. It's pretty close to the horizon, which is not ideal. I was shooting at a very short focal length, thinking I'd leave room for a tail, but the joke was on me because I couldn't […] [Original post on backend.newsmast.org]

This is the globular cluster M15 in the constellation Pegasus. I was only able to get a little over an hour before the fog came in. I would definitely work on this more if I could get another clear night, but it remains to be seen whether I will. #Science #Astronomy

This is five hours of the Eastern Veil Nebula in Cygnus. I wanted a lot more time to work on it. If I get any more, I'll redo this. But it's not looking good. It's looking like clouds and fog. #Science #Astronomy
