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.

He says he took it will a telescope but that looks to be about 750mm of zoom so it could probably be done with an extremely high aperture zoom lens too if you can give it a hydrogen alpha filter
I wonder how did he time it right. This is probably below 0.1s window - the only way I imagine he could pull this off, is to record video at very high frame rate
Says he's got video so I'm guessing this is a still from it?
Still props. Not only does your timing have to be spot on, this type of shot can damage your sensor.
There would absolutely be a filter on the front of the telescope though, is there really still risk to the sensor
I honestly do not know.
Even though you're filtering out a lot of the light, it's still a bunch of glass gathering light to hit a focal point, the sensor. And I've seen examples of sensor damage happening very fast. Definitely wouldn't want to accidentally take a long exposure.
This is not taken with sunlight hitting the lens it was taken with a hydrogen alpha filter which is also different from the usual solar filters, the hydrogen alpha filters black more wavelength and pass only this specific wavelength so despite the image seeming very detailed it is only because the intensity is high relative to it being just a small band of wavelength so there is no risk of damaging the camera sensor
