That sounds like fun! Nice demonstration!

Looking forward to it. Just bought a signed edition in the UK! Loved the Dandelion Dynasty!

Why? Politics in the state or something more specific?

That would be cool! I agree, I was thinking of a by-eye type pointing given the beam width.

Yes, it’s super annoying since this used to be very useful. The issue is it thinks 3e19m is ~56 kpc instead of ~1 kpc but who knows what other units are/will be wrong. Maybe they’ve started using AI for their units?

That’s awesome! I was looking to make something like this for outreach. That’s impressively cheap… I’ll be very curious to hear how you get on with it. What do you plan to do for determining where you’re pointing the antenna?

I didn’t mean to trash talk LSST, just that even with this initial processing and without stretching it’s already close to what you had so it’s already pretty good. I look forward to how deep it can be pushed!

Do you know if the processing was optimized for LSB features or was it the standard pipeline? By eye the depth doesn’t seem that different from your Mihos+2017 paper

Very nice @chrismihos.bsky.social! Do you have a sense of the surface brightness limits of Rubin given your previous work?
