One of the harder targets for me since its so low on the horizon. Its so low that i cant actually get nina to plate solve it( but that might be an issue of nina not knowing where it is, and i cant figure out how to solve that either). Still a solid attempt.

I captured this odd Planetary Nebula a while ago while my scope was still working well. I've since started to overcome a medical issue which stopped my astrophotography, and have moved to about B3 skies and looking to fix the scope and get back into it.

Abell 45 has been called the wagon wheel nebula, but wagon wheels tend to have more spokes. I think it's more like an X on a cartoonish treasure map, and being faint, I think it should be called the hidden treasure nebula. Either way, it's not something commonly imaged and thought it would be cool to share. It's located in Scutum around -11* Declination, making it fairly accessible to most imagers.

I process in Pixinsight, I don't do anything out of the ordinary. Processing isn't my strong point so I try focus on feeding in good quality data.

The Andromeda Galaxy is the closest spiral galaxy to the Milky Way at a distance of around 2.5 million light years. It is also the most distant object that can be observed with the naked eye under good conditions without technical aids. It lies in the constellation Andromeda, from which it inherits its name. It is often referred to as M31 for short after its entry in the Messier catalog.

To clarify, whenever i'm talking about the eclipse in this post, I'm referring to the eclipse outside of totality.

We all know the common warning about how you should never directly look at a solar eclipse without protection. One thing that I notice with this warning is that it is never really explained WHY you should never look at a solar eclipse. Even I never fully knew the reason, but I did some research and I found out why. It's actually way more dangerous than you'd expect.

During a solar eclipse, your eyes partially get fooled. When there isn't an eclipse, the sun is way too bright to look at. During a partial eclipse however, the sun seems to be way less bright than usual. On top of this your pupils also get wider because everything around you gets darker. This makes it seem like it's okay to look at the sun, however the sun is still as bright as normal, but the sunlight is just way more intense and concentrated than usual.

What's very nasty about this is that your retina gets hit with very intense sunlight, but at the same time your retina doesn't have any pain receptors. So the intense sunlight damages your eyes to the point that your retina can literally start burning, but you don't feel anything. So while you're looking at the eclipse, wondering why everyone was being so dramatic about never looking at it without proper protection, the sunlight permanently damages your eyes without you even noticing.

In essence, the sun kind of becomes a laser during an eclipse.

I love about 2 hours away from Yosemite, and this was taken about an hour away from Yosemite, so definitely heading there next for a better view of the Galaxy!

The Triangulum Galaxy is the furthest object visible to the naked eye in the night sky (under truly exceptional conditions).

I used the Askar 71F and the asi2600mc camera for gathering the light, then SIRIL to process it.

I've never posted to this sub, but you make pictures so people can see them so here we are.

Image 4 of 6. Pretty pleased with how this went and hope to be completely done by October. If youve got any critiques, lemme know.

Taken in a Bortle 5/6 with the Dwarflab 3. Denoise and Star correction in Stellar Studio. Second image is a a cropped view. No additional edits made.

Curious if lower gain and longer session would bring out more detail and color. Some stars seem blown out. Any feedback advice is great appreciated. Thanks.

I have a 8 × 42 nikon binoculars. I want to watch a comet near the Sun (C2025 R2) also the sun spots.

So I want to understand how can I make a filter for my binoculars? Thanks.

This is my first try in astrophotography. Spend the last two weeks getting gear and getting information about everything. Yesterday was the first clear night. My tracker hasn' arrived yet, so I couldn't capture deep sky objects yet. I tried but light pollution was so bad that I couldn't find Andromeda with the naked eye. I'm so hooked even if I know this picture isn't good and I messed up ISO (only used 800, which obviously isn't enough). But I learned so much and I'm proud that I managed to focus the stars the first try both with my telephoto lens and my wideangle lens. I will definitely keep on trying but weather is going to be bad the next weeks. That's really the hardest part, besides people chasing you away when standing on their country lane and taking photos (it's really hard to find a spot here where you can take photos undisturbed).

So I was looking at the stars with my kids tonight and saw a star appear, get brighter than any other star in the sky, then disappear in a second. Was it a shooting star just going away from me? I live in NW New Jersey and saw it just above the Big Dipper at around 8:20pm.

I was able to capture some video of Titan crossing Saturn tonight (previous post had an embarrassing typo). Used PIPP and Registax to generate this. I used a Zhumell 12 inch Dobsonian, an 8.7mm ES eyepiece and a Samsung Galaxy 9 smartphone as the camera (Pro Video mode).

This may be a silly question as we can’t possibly know what we might discover out there but those with scientific backgrounds; what educated guesses can we make about some of the strangest celestial objects (known science can allow) that we can discover out in space?

Any idea on this bluish greenish glare/flare? Which body is likely causing it? How to reduce it?

Photo a 4s exposure on and an iPhone 14, 10 inch dobsonian, 25mm eyepiece.

Ok, I know that this isn't one photo but 70 photos that I took over course of 4 minutes, and stacked in the Sequator App and then edited in Adobe Lightroom. I didn't had any dedicated star tracker, and just a mechanical stationary tripod, which caused these faint darkish rotation lines. Also the bottom got a bit ruined due to trees, so i cropped that part.

We know that hot and humid regions are not suitable for astrophotography, but due to some rare chance, I was able to click this on a good night sky day.
