We got extremely lucky and got a tiny window of cloudless sky in an never ending sequence of cloudy nights. Also the conditions were a nightmare with severe light pollution and lights shining directly at our equipment.

  • Samyang 135mm f2.0
  • Fuji X-T5
  • 158 x 5s
  • ISO 125
  • @f2.8

And maybe somebody here can explain to us what the ionized gas is that 'shoots out‘ in front of the comet?

Also do the colours seem to be correct? We tried our best at background extraction and maintaining the true colour, but the raw data was of poor quality. From images of other comets the dust tails normally seems to have a yellow/orange colour and only the plasma tail is blue.

Edit: found the answer to the Anti-tail. It shows the trail of dust were the comet has traveled, which appears to come out at the opposing side because of earths angle relative to the comet and sun.

I’m new to astro, is it necessary to stack so much photos to see this comet? Whats the difference between single shot and stacked in this case? Thanks!

The comet is also visible on one single exposure as it is very bright. It was also visible to the naked eye. But stacking reveals even more details because it improves the signal to noise ratio. Also stacking helps removing unwanted objects like satellite trails, planes or moving clouds.

This I took holding an iPhone on a picnic table. See the difference? All the details that OP managed to get?

That’s extremely good for a phone camera I assume. I did try with my own camera a few days ago. I originally asked because weather conditions in my area wasn’t great for a while, and I don’t know what settings to start off with. I did my best at stacking and editing them with Affinity, although not the greatest, I did manage to capture something haha.

Edit: camera specs
Fujifilm X-S10 + Sigma 18-50
ISO640, F/2.8, 5 sec x 140

It‘s hard to tell from your image, bit it appears you can even get a bit more details if you register your lights onto the comet itself and then stack all the images. I used Siril for the two step registration process.

But nice image nonetheless!

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.

  • 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.
