The STOP-BANG questionnaire is good to get at least some idea of if you have sleep apnea or not. Def talk to your doctor about it! Untreated sleep apnea can lead to some pretty bad health problems later on (a-fib, coronary disease, stokes, hypertension) in addition to just being tired as shit all the time

There’s a Gemini logo in the bottom corner

Hi OP. This community is for OC images of space taken by amateurs.

The trick is to be in a group just for adults. I’ve been active in the Ancients of VRChat for years and there’s always a couple dozen events a week

Hi OP, this community is primarily for amateur photos of space that you’ve taken yourself.

It sure is! The monochrome sensors are also great for narrowband imaging, where the filters let through one specific wavelength of light (like hydrogen alpha) which lets you do false color imaging.

IR is basically the same. Here’s the page on JWST’s filters. No clue about xray scopes, but IIRC they don’t use any kind of traditional CMOS or CCD sensor.

At least for astronomy, you just have one sensor (they’re all CMOS nowadays) and rotate out the RGB filters in front of it.

Few hundred pixels is definitely enough, and kinda overkill (mine goes a few dozen). I think the frequency of the dithers is probably the main thing that could help with the noise

It could also be that you're not dithering often enough. Dithering every 30 mins means you're taking 180 frames before each dither and that'll really let the walking/raining noise build up. you could try doing 30" subs and then dithering every ~10 minutes if that's practical? For me personally I dither after a max of 5 subs (or dither after a sequence of something like LLLLRRGGBB) , but I know I'm also taking longer exposures and have the benefit of automation.

Personally I've never used a GTi or Lumix camera, but if you're able to hook them to a computer with NINA, there is an option to have it dither automatically even without an autoguider

Nice improvement!

WR-134 is the purple looking star in the middle. Don't think the purple color itself is 'natural' but I thought it looked neat and decided to keep it like that. The nebulosity in this image is false color (although the HOO palette is kinda close to true color), and the stars themselves are RGB true color. Even though I was able to get some of the entire Oiii shell around WR134, I decided not to push it too much in processing. At some point I'll shoot it again from darker skies. Captured over a bunch of nights in November 2025 from a Bortle 9 zone.

• StarXterminator to completely remove stars (extracted stars processed separately)

• STF applied via HistogramTransformation to stretch nonlinear

RGB Linear:

Channelcombination to make color image from RGB stacks

• MultiscaleGradientCorrection

• BlurX (correct only mode)

• HSV Repair

• StarX to extract a stars only image

• ArcsinhStretch + HistogramTransformation to stretch nonlinear

Nonlinear Processing

• PixelMath to combine stretched Ha and Oiii images into a color image (HOO --> RGB)

• Shitloads of curve transformations to adjust luminance, contrast, saturation, etc

• DeepSNR Noise reduction

• ColorSaturation adjustments (with Oiii mask)

• More curves

• LocalHistogramTransformation

• Even more curves

• NoiseXTerminator for some small scale chrominance noise reduction

• Guess what more curves its the best tool in pixinsight 10/10

• Pixelmath to add in the stretched stars only image from earlier

  This basically re-linearizes the two images, adds them together, and then stretches them back to before. More info on it here)
