On the last test flight a few weeks ago both the booster and ship did powered soft landings in the ocean (even with the ship’s flap melting a bit)

I’m guessing it’s called that because it’s kinda headphone shaped. It was discovered in the 30’s so I’m assuming only the brightest parts of the nebula were visible to the astronomers.

This image is a combination of false color narrowband images for the nebula itself, plus true color RGB stars (the nebula is mostly red and a little blue in true color). If you zoom in to the center you can see the very blue white dwarf that caused the planetary nebula to form. Also for those curious this is what a single 10 minute long Ha exposure looks like (image total is 83.5 hours exposure). Captured over 33 nights from Jan-May 2024 from a bortle 9 zone.

Sh2-64 is the red nebula to the right of the image. It frames up pretty well with the more golden stars seen in the milky way core. I probably should’ve gotten more exposure time to help bring out some of the dark nebula details, but it was only clear for one night at the dark site (at least the night went perfectly, which is rare for trips out to the middle of nowhere). Captured on June 7th, 2024 from a Bortle 3 zone (Deerlick Astronomy Village)

RIP my home button whenever my SE3 bites the dust

Good ol magnesium shit-rate

They’re still going to launch the 6 operational starliner flights on Atlas V’s, and Amazon has bought several of them for their Kuiper satellite constellation.

Personally I doubt starliner is going to keep flying once the 6 ISS missions are over, regardless of launch vehicle.

May Christ be with you

This is already the highest res (at least in terms of being zoomed in), but here’s the entire uncropped photo

thanks!

Finally done with classes and I got some time to at least star processing my pics. Gonna be a while before I figure out all the HDR stuff, so here’s a pic of the prominences about 10 seconds before C3. It was absolutely nutty seeing them naked eye during the eclipse, and visually through my other telescope. Captured on April 8th, 2024 from Sikeston, MO.

I watched it in imax opening night and the energy in that room was incredible.

The saturation is increased, but looking at the moon through a telescope you can barely see some faint blue/tan colorations that line up with this pic. The blue areas have more titanium minerals and the tan/orange areas have more iron

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

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.

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

The Little Dumbbell Nebula gets its name because it kinda looks like a tinier version of the Dumbbell Nebla M27 (yes, a different palette was used for this pic). It’s really tiny compared to the uncropped FOV. I’m a lot happier with this attempt at it, compared to my 2019 pic of M76 with the same equipment. I know It’s a bit out of season rn but I needed something to shoot at the start of the night. The nebulosity itself is false color, but the stars are true color RGB. Captured over 10 nights in Feb/Mar 2024 from a bortle 9 zone (I could only get a couple hours max per night on it.
