Vibe coding my way through astrophotography

Hello All,

This is going to be controversial as I know you all have dedicated a ton of time to this hobby and been in the trenches learning PI/Siril/etc. That is hard work and I appreciate you all and don’t want this post or my workflow to lessen the value of that.

That being said: I have cheated my way into the hobby and this is my story.

I have been a huge fan of astronomy since I was a kid. I remember going to the planetarium and being mesmerized by the cosmos. In high school in Santa Fe a teacher of mine did a star party at a friends house with his 10” reflector and I was blown away but what we could see. 20 years ago I bought myself a telescope, a mount and some eyepieces. I used it once or twice and it sat in my garage in a bunch of pelican cases.

Fast forward to a few months ago, my friend and neighbor (who’s fairly prolific on here, but I’ll let him decide if he wants to comment) asked if I wanted to see C/2025 A6 (Lemmon). He pulled out his telescope and it was really cool. I thought: hey I have one of those things, I should take it out and set it up. So I did and put my Canon on it with a t-mount and took some (really bad) photos.

It sparked some insane thing in me. I decided I wanted to do this for reals. I did some research and figured out my best bang for my buck would be to buy some cement and build a pier. I found this great article https://tucsonastronomy.org/astronomy/backyard-pier/ and convinced my boss (wife) to let me build it on our backyard hill. (photos here: https://eecue.com/collections/albums_2026-astrophotography)

I decided I needed a real camera, I was going to buy a color one but my aforementioned friend set me straight and sent me a link to a camera + filter wheel combo on Astromart which I procured. I also picked up a guide scope and camera, focuser, and power box all used and negotiated down because i’m cheap. I bought a fanless computer and ran power and ethernet up to my pier.

I noted that I’m cheap, I’m also not a fan of Windows, I have been a software engineer for over 30 years so I wanted everything to be on Linux and/or Mac. Here’s where it gets controversial.

I have two young children (1.5 and 3.5 year olds) and I have very very limited free time. I do not have the time required to learn a whole new workflow and complicated (and dare I say, not great UI/UX) software applications to process my photos. I am also a big fan of agentic coding and use it extensively so I decided to vibe code my way through astrophotography.

I used Claude to help dial in Kstars/Indi/Ekos. Once I started getting subs I had Claude write me a python processing script that drove Siril as well as some ML models directly to handle the stacking and processing. My workflow is currently as follows:

1) Select targets in Kstars (I also vibe coded an macOS app that shows me all the targets available with nice photos/etc so I can make good decisions on what I want to capture)

2) Go to sleep

3) Wake up

4) Run an rsync command to get my new subs onto my M1 Macbook Pro

5) Tell Claude about what I captured

6) Claude runs the scripts and opens up the processed photos in Preview

7) If i’m happy (which for the last few captures I have been) I copy them to Photos which uploads them to my website (via another vibe coded workflow)

8) I tell Claude to upload them to Astrobin

9) Sometimes I post to reddit too

That’s it, it’s roughly 1-2 minutes of my time total.

I’m shocked at what I’ve been able to capture in my bortle 9 (according to the site but I think i’m likely a bit closer to an 8) … i’ve been having a ton of fun with this, recently added an all sky camera and bought a new mount (Losmandy G11 which I got for a steal with all the nice upgrades) … next up is getting a bigger scope so I can enjoy galaxies.

I do want to remind folks that this hobby should be fun, so please be gentle to a noob.

Happy to answer any questions. I am unable to open source my code though since my work prohibits that.

I don’t see a way to delete or move a post, I don’t think this is the right forum for this, sorry.

The mods will move it if need be.

Have all the images on your bin been processed this way?

Dave Bullock avatar

Yep, I have never processed an image by hand, all done via Claude and the scripts it wrote.

As many will tell you, you are likely missing on some of the most fun aspects of the hobby; but, hey, I am 26 years later in the point in life of my kids compared to where you are!

Honestly I don’t love processing photos (even outside of astrophotography) … I just like capturing and sharing images. The whole processing part just sounds very tedious.

I agree. The processing part is indeed very tedious; however, it’s also like magic. Once you learn how to process data, there is a certain excitement that comes from seeing what you can reveal in your images. It might take a while but it can become very addicting as you learn how to create something beautiful from all that data that flows from your telescope. Good luck with it!

As a software engineer - I will say that AI can be a magnificent tool for some jobs, indespensible in some cases… Astro image processing is not one of them…

If you are happy with the results it’s producing, then that’s what matters… It is, however, a long way off being able to produce anything near the quality of a quality processing session done by someone who knows the tools well.
