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.

Neat animation. I notice you have lots of forest around so you won't be able to see Polaris until it's high up and mixed with other stars. How do you polar align? I'm new to this and at my house by the time I see Polaris I can't differentiate it from the other stars to be able to polar align.
Polaris is the one start that doesn't rise. It's always at the same height at the same spot. Learning the constellations of Ursa Minor and Ursa Major is a great first step into observing the night sky.
Finding the big dipper (the seven bright stars of Ursa Major) is usually very easy. Then you just follow the line formed by Merak and Dubhe until you find Polaris.
I didn't think about that it doesn't move in the sky. That's definitely going to change my perspective on this. I was able to generally find where it should be due to the big dipper but had trouble figuring out quite which star it was
Polaris is pretty easy to find, and it shouldn't really change its position in the sky much. Basically, find the big dipper, find the forward two stars of the cup, and then follow the line they make away from the bottom of the cup. In about two outstretched fists, more or less, you'll arrive at a fairly unremarkable star that's more or less on its own (you'll see fewer or more companions depending on your light pollution). If you're asking yourself "is that particular star right there Polaris?" the answer is likely yes. If you're asking "which one of these is Polaris?" and you're not in an especially light pollution free area, you probably messed up and you should try again.
Thank you for the tips and advice. I'll reference this next time I go out
If you get close enough and feed a camera feed through some guiding software to make corrections it becomes far less important to be spot on, especially at short focal lengths
