Sh2-114 (the Flying Dragon Nebula) is a very faint and rarely imaged nebula located in the constellation of Cygnus. The nebula has not been studied much and still doesn’t seem to be a common target for astrophotography. This large curving filamentary structure appears part of a supernova, but no supernova remnant has yet been identified as the source.

After about 13.5hs and four sessions, the weather turned, so I have to be content with the data for now. Processing was challenging and I believe another 10hs or so would be beneficial. It was fun making the dragon appear.

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.

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.
