TURD mod for recoloring, and conformal decals for adding PNGs/text as flags on the side of the vehicle

Had an exam in the morning but now I’m just chillin this whole weekend

Every store needs a man zone

Full of soup

What equipment/settings did you use?

Damn 800+ frames. How long did it take to stack?

Had a previously banned user from a discord I moderate join back months later with my wife’s name as their username and a photo of her as the pfp

It's that time of year I replace my desktop wallpaper! All of these are pics I've taken throughout 2024 with my deep sky rig. It was an incredibly productive year, and I ended up getting 773 hours of exposure time across all of my images (up from 598 hours in 2023!) If you want to see the original pics/acquisition info, check below.

smoke weed, drink, jerk off, and play vrchat!

Alternatively spend New Year’s Eve with friends in vrchat, drinking beer from your fridge, and having your bed only 20 feet away in the next room

Go for it

So technically 32 Cygni is just the bright star in the pic, and the rest of it is just hydrogen gas floating around in space. The constellation Cygnus has a ton of this hydrogen-alpha gas floating around, and I kinda just pointed at a semi-random spot in the constellation to get a pic. Although this was taken with an Ha filter, the stars are true color RGB, and I mapped the Ha channel to red so it closely resembles the actual color of hydrogen-alpha. Also for those curious here is a starless version that better shows the faint nebulosity/structures. Also pls ignore the crunchiness around 32 Cyg itself, it's an artifact of my camera's microlensing + the star removal program I use. Captured over like a dozen nights in December 2024 from a bortle 9 zone.

• Blink

• ImageIntegration per channel

• DrizzleIntegration (2x, Var β=1.5)

• Dynamic Crop

• DynamicBackgroundExtraction

  duplicated each image and removed stars via StarXterminator. Ran DBE with a shitload of points to generate background model. model subtracted from original pic using the following PixelMath (math courtesy of /u/jimmythechicken1)

  $T * med(model) / model

Narrowband Linear:

• Blur and NoiseXTerminator

• StarXterminator to completely remove stars from each the image

• HistogramTransformation to stretch nonlinear (calling this the Ha image now)

Broadband/RGB linear:

• ChannelCombination to make color image from R G and B stacks

• StarX (correct only)

• SpectrophotometricColorCalibration

(duplicated image at this point, to be used for stars only processing later)

• StarX to completely remove stars (at this point it's just background, with a little bit of signal in the R channel)

• Blended unstretched Ha image into the red (and a little bit of the blue channel) with this pixelmath:

  R = $T+B*(Ha- med(Ha))

  G = $T

  B = $T+B*0.2*(Ha- med(Ha))

  honestly can't remember what I used for the B constant, but the default is 2 in my pixelmath ¯\_(ツ)_/¯

• HistogramTransformation to stretch nonlinear (calling this the Starless image now)

Stars only processing:

• HSV repair to fix blown out star cores

• StarXterminator to generate an image containing only the stars (without any background)

• ArcsinhStretch + Histogramtransformation to stretch nonlinear (Calling this the Stars image now)

Nonlinear:

• LRGBCombination to add the stretched Ha image to the stretched Starless image as a luminance layer

• NoiseXterminator

• Background neutralization

• Several curve transformations to adjust lightness, contrast, saturation, color balance, etc

• LocalHistogramEqualization

• Another round of noiseX

• Pixelmath to add in the stretched RGB Stars 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)
