A not entirely successful attempt to get a wide-field image of the crescent moon with the Sickle in Leo. I seem to have cut off a bright star on the bottom (Algieba), making it harder to see the sickle shape. At this focal length it's hard to see what you're framing. #Astrophotography #Astronomy

I have the plug-in Gradient Xterminator. More helpful on some images than others. I'm guessing this is more advanced.

Thanks, Bernd!

Thanks! I do like the background much better. I could have done with more eyebrow, but I guess you can't always have everything all at once. It's a challenging hobby.

That's a new one on me.

Before this past round of clouds and rain, I looked at the sun and saw no active regions. I thought, well, solar maximum is ending. Now the clouds are gone, and look at it today. #Astronomy #Astrophotography

Just for fun, the moon with M44, the Beehive Cluster. I had to wait for the clouds to briefly part, and there was still a bit of cloud action down by the moon. #Astronomy #Astrophotography

Thanks, Neil!

It's really small, but it's there. Even the colors, to some degree.

Photometric color calibration? I can say/type it, but I haven't figured out how to use it yet. But I added three hours of data that didn't have the problem, and that helped a lot. That one wasn't a final anyway.

Thanks! I remember you from my old Twitter days.

Thank you!

Quick cell phone pic of the moon with Jupiter this morning. The clouds are coming back.

I was able to get another three hours of NGC 7293, the Helix Nebula, and I think I'm ready to call it done. Especially in light of the coming rain. #Astronomy #astrophotography

I can't type today. DBE, I meant. In PixInsight.

I actually ran DBA on this twice. I'm not sure why that gradient is so stubborn.

It's really a balancing act sometimes.

Catherine Ryan Hyde @catherineryanhyde.bsky.social · 4d

Thanks, Bernd. I hope to work on it a bit more tonight. Last night the seeing was garbage, and where I live it's never very high over the horizon.

In case it doesn't go without saying, when I said you can see the Double Double, I just meant the two pairs. I wasn't suggesting I resolved all four stars at 250mm of focal length.

This is a lightly annotated image of the constellation Lyra. Even at this short focal length you can see the Double Double and the Ring Nebula. It gets pixellated when you zoom in to see, because no way could I post the full image. Even the jpeg was 35MB. #astronomy #Astrophotography

You were probably smarter than me.

This is NGC7293, the Helix Nebula. I got a couple of hours of it last month, but that didn't feel like enough. I got another couple last night. I'd like to double the exposure time, but the seeing is supposed to be awful tonight, and there's rain coming. I'll try. #Astronomy #Astrophotography

An hour of the open star cluster M39. It's what I was doing while waiting for the moon/Pleiades to rise. #Astronomy #Astrophotography

A fool's errand right from the start: a bright moon occulting the Pleiades. Of course the moon nearly obliterates the stars in the Pleiades, so this is a composite of five different lengths of exposure, plus I had to brighten the stars. Worth it for the challenge. #Astronomy #Astrophotography

This is a different comet. There are two in the northern hemisphere now. This is C/2025 A6 LEMMON, a single 60-second exposure on very low ISO so it wouldn't be too noisy. Kind of noisy anyway. #Astronomy #Astrophotography
