The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Roll Your Own All-Sky, Raspberry Pi Camera
Plate solving - identifying constellations and deep sky objects by the relative positions of stars - is a pretty common part of astronomy software and possible on a raspberry pi. For example https://github.com/dstndstn/astrometry.net
I'm not aware of anything that can, say, identify a meteor and differentiate it from a plane or satellite, but I'm sure it's possible.

Hey guys, color calibration question.
for platesolving to work in Siril, the focal length and pixel size should be fairly accurate to work. If you drizzled, that would reduce the pixel size by whatever drizzle amount you used. You can also upload a jpg to astrometry.net to find out what the parameters are in a blind solve

recently took a photo from my village with low light pollution, when i tried putting this in astronomy.net to match the constellations and stuff it always says failed, can anybody help?
Try astrometry.net instead of astronomy.net :)

Online editing
Starfixer.org is pretty cool and so is astrometry.net. But I'll give you my 2 cents as both an iPad Pro owner and also a faster computer. The math that happens when we do our processing is advanced - blows my mind. The iPad CPU is great for its use case, but you aren't going to find Chat GPT or other high-end, compute intensive workloads running on today's iPad. You can connect to the cloud, but you can't run the workload. As you said, we can't even find an app to open a single FITS image file because that along doesn't help many people do much if you can't stack and apply the other compute intensive work.

StarBerrySense aboard POEM-2 performing as expected, design as well as function validated.
It most certainly is not better than astrometry.net. I just assumed that it would be beyond the capabilities of a Pi. We would need to put the index files on the Pi but could cut them down because our limiting magnitude is about 6.

N.I.N.A Three Point Polar Alignment ASTAP Not Plate Solving
I think I may have hurt myself in confusion. I just imported my target from stellarium and hit slew and center. This time it slewed and centered and uploaded to astrometry.net currenty I'm waiting to see how it goes with that. This is what happens when you take like half a year off from this hobby lol

How can I photograph something I can't see?!
You can upload a photo to astrometry.net and wait 10 minutes for it to tell you where you are pointed in the sky, make manual adjustments, and repeat. The way to make this efficient is to control your mount and camera from a computer, and use a program like APT or NINA to do the platesolving. That way your goto function is precise and there's no question about what you're looking at.

I need hellp with this picture of C/2022 E3 I took lasst night
I took 186 6 second exposures at 200 ISO at 105mm(I live in a Bortle 7 area, edging at 8, needed to combat light pollution somehow), I also took 20 calllibration frames of each Dark Flats and Biases, and sent them into DeepSkyStacker for stacking, I know it has a comet feature, but I couldn't see the comet in my pictures, sso I hd no way to tell it where the comet was, so I did the norml steps, and thought, i'd get a small line, of the comet's movement, and that'd be enough for me, but after stacking and stretching the image, I am seeing no signs of the comet, and astrometry.net is unable to plate solve the stretched image(cpu limit reached!). I don't know what's wrong with it, other than the obvious clouds, but I've had that before in my andromeda pictures and DSS handled it well, and astrometry.net was able to plate solve it no problem.

Is there a way to find an island from its shape?
http://astrometry.net/ uses a fairly standard technique to do this for stellar images, but I don't think the technique can be expanded to polygons

Can we detect asteroids by subtracting a GAIA search from sources extracted from an image?
In case you're curious, here is the current status of my set of pipeline scripts. So far, it's only for calibrating/platesolving images, as well as overlaying known asteroids.

The Tarantula Nebula (NGC 2070)
You're welcome. I think it's a fun project to learn python. Here is most of my code if you want to check it out.
What are some alternatives?
When comparing astrometry.net and astro-pipelines you can also consider the following projects:
WatneyAstrometry - Astrometric solver library and app for .NET Core
indi-allsky - Software to manage a Linux-based All Sky Camera.
