JWST primarily looks at very large objects that are far away. Titan (and really everything in the solar system) is relatively close to us, but are tiny in comparison to galaxies/nebulae, so their actual size as they appear in the sky is a lot smaller.

Thanks to my north facing balcony, I can only photograph the moon when it's at high declinations. Fortunately it was at +27 dec the other day, and it was early enough for me to be awake to shoot it! Captured at 10pm on April 12th, 2024.

A scrotal solar eclipse

[–] lefty7283 4 points 7 months ago

This is an animation of every 1/4000" frame I took during/around totality. For most of totality I was looping HDR sequences and had one of these frames roughly every 15 seconds, but around each contact I bursted these short frames to get the beads. The animation lasts for the entirety that my solar filter was off, which was about 13 seconds before/after each contact. I think it's cool seeing the motion of the moon relative to the sun like this. Since imgur compression is kinda shit, here's a (slightly) less compressed version on youtube.

Which phone cam did you use?

[–] lefty7283 9 points 7 months ago

So it turns out camera sensors are perfectly fine being exposed to the last ~20 seconds of sunlight before an eclipse. I’ve decided that if I still have this cam in 2045 I’m going to sacrifice it to the sun by not putting the filter back on after totality, and letting it document its own demise.

I’ve been making them for the last few years, and the old ones should be linked in my other comment here. And yes, they were on Reddit, here’s my old /u/ if you’re curious https://old.reddit.com/u/azzkicker7283

Holy shit this was the most awesome thing I've ever experienced. I've been prepping for this eclipse ever since I got clouded out at the last minute for the 2017 eclipse, and almost everything went perfectly! (I didn't even hit eclipse traffic on the way home!) With the camera automated I got 163 HDR pics during totality, plus more from the partial phases, so expect to see some more pics in the coming weeks!

I really like how the diffraction spikes turned out from the Bailey's Beads, and how the blue turned out in my totality pics. I tried to keep the editing minimal on this, and just did some minor contrast and saturation adjustments (see below for more details). The corona in the image is definitely bluer than how it looked irl (which was mostly just white), but the prominence color is pretty close to what I saw through my other scope. I suspect it's because of the custom white balance I've had to use for my astro modded cam. For those curious here are my other C2 pics, unedited other than cropping
