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!
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.
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.
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.
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.
If your post is removed, try reposting with a different title. Don't hesitate to message the mods if you still have questions!
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.
My second (and first successful) try of the orion nebula. Any advice for editing out the noise and these stripes? What are these?
Camera: Panasonic Lumix G85 Lens: H-FSA100300 (100-300mm f4-5.6) Settings: f6.4, ISO 6400, 5"
1020 pics at 5s each + calibration frames
Total exposure: 85 minutes / 1.4 hours
One trick for removing walking noise in post is to use a tool like StarNet++ to decompose the image into stars and nebulae, then mask out the nebula in the image. Invert the mask and desaturate.
Like others said, if possible, try dithering in the future. It'll help to minimize walking noise to begin with. It's pretty easy to configure in most imaging software, but typically requires autoguiding.
I don’t have an autoguider and obviously don’t want to do it manually, so I’m just doing this in post next time
