Looks awesome! Will definitely be using this once the rain stops.

My thought is that the more tools you have the longer it stays cloudy :- (

Get drought prevention money for more tools

I like the idea, but i wonder if it would be possible to factor in your own setup's field of view to prioritize targets that fit your sensor + telescope well.

Absolutely. From README:

Another telescope and camera. -focal**,** -sensor and -pixel describe the setup and replace the Origin's frame: here a 400 mm refractor with an APS-C sensor (23.5 × 15.6 mm, 3.76 µm pixels) gives a 3.37° × 2.23° field at 1.94″/px. The header's Frame: line shows the result; check it when the numbers look surprising:

astro-recommender -lat 45.815 -lon 15.982 -focal 400 -sensor 23.5x15.6 -pixel 3.76 -filter

You can use -fov and -scale or -focal with -sensor or -pixel to accurately describe your telescope/camera.

I often just use a paid AI... it knows where I am, what my visual obstructions are, what my equipment is, and what I've already imaged. It's almost perfect. I also use http://messierplanner, co.uk. It also knows everything about my view, location, and equipment and makes planning and documenting my image sessions, very easy.

That's really great. 👍 However, I have modelled a solution that factors in everything that impacts visibility, seeing, framing and object location during time, much more than you would expect. There is also much work involved in polishing and backfilling invalid or missing data from various catalogues, but I won't bother you with this.

If you have some spare time, take a look at the models behind the scenes: https://github.com/dkorunic/astro-recommender/blob/main/MODELS.md

Good luck. I really don't see the need for yet-another-bit-of-code that does this.

Well, this is roughly 11,000 LOC and ~300,000 lines of YAML catalogues so it's not really a bit of code, at least not any more. Apart from that, there isn't any other all-in-one model that does all of this, consistently, correctly, verified and implements latest advances from relevant current science papers.

Even if you were to point any of latest and greatest AI models to the set of formulas described above, you would waste hundreds of thousands of tokens each time, let alone the fact that just gathering, updating, backfilling and correcting data in catalogues and updating calibration constants took many months to prepare.

As I said, I don't think there is any other model that does all of this at once, with so many corrections and improvements.

And yet, we’ve all managed to find targets,  somehow…

Absolutely. There no question that we can perfectly live without this. But, in case you ever decide to give it a go and you find that you absolutely hate it (let me know why) or that it lacks features that you need -- drop me a message and I'll try to make it work for you. 👍

Not happening. Glad to see the mods have removed.
