Another useful ChatGPT use: Compute RA and DEC offset for a comet image

With the short window we have for Comet C/2025 A6 Lemmon right now, I don’t have time to fiddle with trying to frame the comet in such a way that the comet nucleus is on the corner and the tail runs diagonally across the frame so I can get as much comet tail as possible. Usually I would use orbitals plug in or go into framing and work to reset it manually. Not anymore. Maybe you all have a better way to do this already, but I just tried to see if Chat GPT could compute the RA and DEC offset for me based on my set up and sure enough it did. I was able to even tell it to give me a 8% buffer so it wouldn’t just be smack dab in the corner. At any rate, just thought I’d share another use case for it that just saved me a ton of time.

A ton of time? Really? It takes me maybe 2 minutes to get the right framing on my planetarium…

That’s a cool idea Sean! It’s interesting figuring out what the AIs are good at and not good at.

I use SkySafari on my phone. It already has my fov and rotation angle put in so all I have to do is frame it up how I want and copy the coordinates. Has been so bang on accurate that I pre-programed coordinates for an imaging run at like 5am at my remote observatory and the comet was perfectly framed how I wanted when I checked my images after waking up.
