Wow this looks amazing. If you don‘t mind I have some questions.. I assume this was shot with an Ha filter to reveal the structure on the surface, otherwise it would be all white? Also what is the need of 10% of the images? Do you stack them? One exposure should have enough signal shouldn’t it? And last but not least what focal length does your telescope have?
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.
Ha filter: yes, I used the Lunt60 which has two different filters, a tunable elaton that hones in on a particular wavelength, and another more broad filter that rejects the rest of the energy.
10% images: the general term is "Lucky Imaging" but imaging things through the atmosphere is subject to seeing, or that shimmery effect above the ground on a hot day. The air is moving so it turns the atmosphere into what looks like looking at the bottom of a lake while ripples pass by, hence rejecting so much data
AutoStakkert does some magic with multiple exposures that I still don't quite grasp yet.
My telescope is 60mm diameter, f/7, for a focal length of 420mm.
Thank you very much for responding!
I've never directly looked at the sun so I'd always assumed it was in color.
It puts out every in the spectrums we can and can't see. This was taken with a mono sensor and through a very strong set of filters so there wasn't really any color data to be had. That being said a lot of folks will add that classic orange hue that you see. I decided to stick to white.
Looks too dark, might be at night.
It was definitely night for somebody on the other side of the world :)
