Happy to finally be able to share some of the work I've done with Cas A. Here's what I call the "technicolor dreamcoat" version that includes infrared light from JWST, x-rays from Chandra, and visible light stars from Hubble.

What does Neptune look like? Reprocessing of a view from the Voyager spacecraft taken in 1989.

Oh well, enjoy this low-effort view of M82 from JWST comprised of pipeline images that had the least problems.

Check out this interactive JWST article from the NYT. This version of Cas A is the one I worked on. 😀

I've been meaning to check out this early release Euclid data. It's pretty amazing. I've been watching the image releases and feel like they have a few issues with color balance and clipped histograms. After some investigating I still think that's true. Here's a roughly processed image. You can compare them yourself and see if you agree. https://www.esa.int/ESA_Multimedia/Images/2024/05/Euclid_s_new_image_of_star-forming_region_Messier_78

My computer is down while I wait for a replacement power supply. I drew a phoenix on a tiny piece of scrap board to test out some pencils I bought last month to pass some time.

tonight's question: do x-ray astronomers care at all about what bands color imagery generated from their data use? does it matter?

fun fact: x-ray images come from event files and each photon gets its energy level recorded, so you can divide the bands however finely or coarsely you want! this does not make it easier to decide what color to make things...

Did some super quick banding denoise (left lots of artifacts) on the HH211 data. But look, there's a whole other field over there! I find myself once again wondering how nice this would look without that big gap in the middle.

This view of IC348 from JWST is also just sitting in the archive. Really quick processing; didn't clean up all of the cosmic rays.

I totally missed it, but this image released yesterday and I'm told it was featured widely. Didn't know this was Chandra's Halloween release. 😆 https://chandra.harvard.edu/photo/2023/msh1552/

A quick experiment with some old HST data for V838 Mon, which is a beautiful light echo. Here, instead of using multiple filters to create color for a single epoch, I've used multiple epochs with same wideband orange (F606W) filter layered over itself, showing what parts of the spherical volume of gas and dust were revealed over multiple years all at once. Redder parts are older parts of the echo while yellow and bluer parts are younger.

It's been a while since I've gone to the MAST to find some data... I'm just so sad to see the alignment issues persisting so long. I guess this is just what the pipeline is going to produce, isn't it? This is it.

Mostly blurred/misaligned stars in the galaxy M82. A few areas are nice. To be clear, It should all look nice. Stars should be dots, not smears. I can make a clear image if I download less processed images and align them manually. It just sucks.

Got a few Tarantula datasets downloaded. Just some quick messing around with the HST imagery. It'll be combined with some other telescopes later.

My friend sent these photos from Oklahoma. I’m totally amazed! Nothing here yet in Modesto, California.

Glowing reddish purplish sky with stars and outdoor lighting visible at the same time. There's a USA flag jutting out from the left.

anyone know some good software for working with FITS cubes? Ideally I'd like to be able to either save all of the slices individually or flatten them all into a 2D image

Sometimes you just gotta do some heavy lifting and remove a few quadrillion trillion tons of burning hydrogen out of the way.

The same nebula, without stars to obscure the view.

(I'm both happy, and slightly offended that I never get comments about how "doing that is, in fact, abusing ants"... I may however make such comments... but that's a whole other story. Nah, only puppies and kittens get this kind of worry...)
