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.
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.
-
See this page for more details
- 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.
-
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.
- 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.

I've just begun taking astrophotos and this is an amazing photo. The weather hasn't cooperated much lately so I'm trying to understand using Siril as well as everything to do with my new telescope and camera. Did you also have a dew heater on your camera/lens? Did you take flats and bias and darks too? Sorry if too many questions, you just seem to know what you're doing as that photo shows.
P.S. I don't see any elongated stars. Ah, wait, I looked at the full res version on telescopius and I see the elongation. It seems to radiate away from the center of the image in all directions. More so as you leave the center. Something with the lens?
Well thank you very much! I‘m still a beginner myself, for our first tries the videos from Nebula Photos on youtube helped a lot, especially the workflow in Siril. This is only our second serious attempt, so I don’t know if my help is of any value, but I‘ll try anyway.
Yes we used a heater for the lens, the complete setup was covered in ice, so this helped a lot.
Yes I did make calibration frames but didn’t use them as I got problems with the result. I forgot that I shot with the dual narrowband filter and used an lcd for flats.. But GraXpert handled the very strong gradiant quite well.
What I think helped the most in terms of quality and artifacts was the constant use of dithering. As the star adventurer 2i obviously can only dither in one axis we dithered manually on the other every 10-15 mins. Hope this helped!
Thanks for the reply and the reference to Nebula Photos; I'll take a look there. From your photo, I see your weather was the same as mine lately. Hopefully there will be some clear skies again soon. Good luck, thanks again.
