Testing an attempt to stack the Milky Way from the city using a GoPro

I was wondering if there is in the Market a auto polar align harware ? Will be Amazing to have a setup that auto correct itself!! regards

I'm looking to get into mono imaging and using a slightly larger and longer scope (something like a C6 or even a C8). I know that with a longer scope I can't do tracking the same way as I do with my 72mm refractor. Which would would be better?1) Get a camera with a guide scope built in - like ZWO ASI585MM-Air or ASI2600MM-duo (or air) 2) Get an off axis guider and use my current ASI290MM guide camera 3) Getan OAG and a new guide camera 4) Something else let me know your thoughts - I plan on starting to make this just towards the end of July 2026. My current setup is: Scope: AT72ED-II w/ .8 FR/FF with EAF; SV165 30mm guide scope f/4.0 Camera: ASI533MC-Pro; ASI290MM guide Mount: AM3 with ASIAir Plus Filters: ZWO 5 position filter wheel; ZWo UV/IR-cut, Optolong L-Extreme, Optolong L-Synergy

This article from the University of Science and Technology of China is brilliantly written… I want to share it with everyone. Whether viewed as popular science commentary or a piece of humanistic reflection, it is outstanding. What will ultimately doom this planet has never been extraterrestrials. It stems from our own arrogance and ignorance. Some wage wars, some harm nature, some oppress their own people through class hierarchy, some discriminate against others based on innate traits such as race and gender, and some hurt those they love with harsh words… Yet amid all this, there are still people fixated on a may non‑existent enemy, even using it as a distraction to indulge their greed and keep harming this tiny, fragile pale blue dot.

In the Canary Islands we have always had a more or less stable climate, but since last October we have not stopped chaining calima episodes with storms or storms I haven't remembered a season like this for a long time.

What is the purpose of the recent release of UFO-related documents by the United States? That's intimidate

Hawaii has had the longest overcast night sky I've ever sent here. 3 months of clouds. I think it's a record breaker. First long opening was a couple nights ago but since then it's been clouds at night.

Using the iOptron Cube Pro and trying to get it aligned with the moon. But when I select the target my mount rotates directly north. In the photo, the bright spot is the moon and you can see which way the scope is pointing after I select moon to target. All my coordinates are correct.

I have an iOptron Cube Pro that does all the tracking, so would the ASIAIR be worth getting? I'm intrigued with the idea of less cables, and being able to use my tablet wirelessly just for the camera control and not the mount control, since that be redundant. Does anyone have something similar and what are your thoughts on it?

why are distances so large in the universe that it makes communication impossible ? (+why is lightspeed so slow)

The cosmonauts observed the dark side of the moon and cameras seemed to record at least 3 flashes of meteor impacts ! Dangerous place with many impacts probabilities.The eclipse looked like the beginning of our usual eclipse but after the moon is much larger in front of the sun.
