A lobster claw is not what I'm seeing here.
Astrophotography
Welcome to !astrophotography!
We are Lemmy's dedicated astrophotography community!
If you want to see or post pictures of space taken by amateurs using amateur level equipment, this is the place for you!
If you want to learn more about taking astro photos, check out our wiki or our discord!
Please read the rules before you post! It is your responsibility to be aware of current rules. Failure to be aware of current rules may result in your post being removed without warning at moderator discretion.
Rules
- I | Real space images only.
-
Astrophotography refers to images of astronomical objects or phenomena exclusively.
-
~~Images that show objects or people below the Kármán Line (100km) will be removed.~~ We won't be enforcing this rule for now, but as the community grows eventually we will split and have a separate space for just landscape astro.
-
Images must be an accurate representation of a real astronomical object.
- II | Original and Amateur Content Only
-
Image posts can only be images that you have captured and processed yourself, or discussion about capturing and/or processing your own images.
-
Images acquired from public sources, professional observatories, or other professional services are not allowed.
-
If you have done a drastic alteration or reprocessing of a prior submission, you may repost your edit - but only after a minimum of one week has passed.
- III | Post Types
-
Image posts are to link directly to the image, not to landing pages, personal galleries, blogs, or professional sites. Link to these in the comments. (AstroBin and Imgur, are allowed)
-
Questions are welcome here for the time being.
-
Links to blogs, articles or external websites should be interesting and promote discussion about amateur astrophotography.
- IV | Titles
- All image posts should just include include the name of the object being photographed. Extra info such as equipment, it being your first image, or other information should go in a comment along with your acquisition info. Please see this page for more details.
If your post is removed, try reposting with a different title. Don't hesitate to message the mods if you still have questions!
- V | Acquisition and Processing Information
-
All submitted images must include acquisition and processing details as a top-level comment. All posts without this information may be given a warning, and if not updated will be removed.
-
This includes the telescope, mount, camera, accessories, and any other pieces of equipment you used to capture the image.
-
You must also include processing details, i.e. the programs you used and a general rundown of the workflow/processes you used within those programs. “Processed in Photoshop” is not enough.
It actually looks like it's namesake!
This is a combo of SHO hubble palette + true color RGB for the stars. Captured in October 2025 from a Bortle 9 zone.

Capture Software:
- Captured using N.I.N.A. and PHD2 for guiding and dithering.
PixInsight Preprocessing:
-
BatchPreProcessing
-
StarAlignment
-
Blink
-
ImageIntegration per channel
-
DrizzleIntegration (2x, Var β=1.5)
-
Dynamic Crop
Narrowband linear:
-
MultiscaleGradientCorrection using MARS project data (had to do good ol fashioned DBE for the Sii channel)
-
BlurXterminator
-
StarXterminator to completely remove stars
-
STF applied via HistogramTransformation to stretch nonlinear
RGB Linear:
Channelcombination to make color image from RGB stacks
-
MultiscaleGradientCorrection (this is some seriously impressive shit!)
-
SpectrophotometricColorCalibration
-
BlurX (correct only mode)
-
HSV Repair
-
StarX to extract a stars only image
-
ArcsinhStretch + HistogramTransformation to stretch nonlinear
-
Slight curves saturation boost
Nonlinear processing:
-
Pixelmath to combine stretched narrowband images into color image (SHO/Hubble palette)
-
SCNR > Invert > SCNR > Invert to remove some greens and magentas
-
DeepSNR
-
Shitloads of curve transformations to adjust luminance, contrast, saturation, etc
-
HistogramTransformation to further stretch the red channel a little
-
more curves
-
NoiseX for some small scale chrominance noise reduction
-
Pixelmath to add in the stretched RGB 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)
