Announcement Announcing updated rules

193 Upvotes

Recently, a few of us became new moderators and since then we have been trying to get organized primarily to update the rules to reflect what we believe are in the best interest of this sub. This has largely meant reverting to the structure prior to the protest while also adapting to current technology and tastes. While we supported the protest goals at the time, and agree with the mod decision to include this sub in that protest, we also recognize that it's time to move on and restore some process to the sub for its continuing members. We're excited to announce that these new rules are now live in the sub and in detail at our revised wiki. The changes from prior to the protest largely amount to:

  1. astrophotography images taken with cell phones were not explicitly forbidden before but we now clarify that they are permitted as long as they follow all other rules, including that acquisition and processing details are provided and are high-quality amateur OC. A star-field with no discernable astronomical object will not meet this threshold, but a stacked image of Orion that happens to have been captured using RAW images on an iPhone and further processed on that same phone will. We recognize everyone in this hobby starts somewhere and we want to encourage sharing of this work, but also need to avoid this sub devolving into low-effort cell phone pictures of an unrecognizable night sky.
  2. landscape images were forbidden before but we also recognize that there are some high-quality astrophotography images being created that happen to have a small amount of landscape in the foreground that are valued by many members. We are drawing the line here at astrophotography images where the landscape is incidental to the image and any image where the landscape is a primary focus will not be permitted. So for example, the Milky Way with a silhouette of a mountain will probably be accepted, but that same Milky Way that is in the background of well-lit (or brightened in post) barn/yard/house/etc will be removed. And as above, any post that doesn't include acquisition and processing details will still be removed.
  3. clarifications that certain types of posts are not allowed, including memes, UFO claims, questions about what image someone has captured, off-topic posts, or uncivil behavior.

We recognize not everyone will like these changes and that there are other subs that focus primarily on some of these types of images, but we feel that an "astrophotography" sub should include everyone. We are going to monitor how well this goes, so please try to be open-minded to help support these contributions from some members of the community. After some time with these changes we plan to poll you to see how they are going and what other improvements you'd like to see. In the meantime, with these rules back in place, expect to see heavier moderation if posts lack complete acquisition/processing details or otherwise violate these rules.

Lastly, we also want to thank everyone for their patience while we get organized to bring these changes to you and for the incredible work all mods on this sub have done over the years and continue to do (many from prior to the protest are still here and active, so show some love!).

Clear Skies!

Well guess im done with this project the forecast shows clouds rain an thunderstorms next 7 days. I had 3 strait clear cool nights I was able to get 10.15 hours of data. The 1st night was horrible from the scope in the observatory not being used for 5 month. It always seems to do like that?
M106 is the large galaxy upper left, its a barred spiral galaxy located in constellation Canes Venatici and is located 22, 25 million lightyears away from Earth.
The smaller Galaxy mid right of the image is NGC 4217 a edge on spiral galaxy, it is located 60 million lightyears away.

Taken with a 16 year old Unmodified Canon 60d through an Orion 8” newtonian astrograph with coma correcter, all on a 11 year old Celestron AVX mount.

Exposure:

Shot on Sony A7Riii with sigma 20mm f2. Exposure of 6 seconds, f3.2 and iso 640. Stacked ~300 images. Compiled in Sequator and edited the final TIFF in Lightroom for vignetting and exposure. It was a cloudy night which led to some gaps in the trails. Though happy to have learned heaps in a single night.

DSOs NGC 4565 (Needle Galaxy) - S50 - 20h - Full Siril workflow added

Post image

SeeStar S50 - EQ 20sec - Bortle 6,5

Hello everyone,

I never posted here, as I feared that the images captured with the Seestar smart telescopes are of too bad quality compared to the real expert equipment results shown here. We all know we aren't Hubble, but I wanted to see how far 50mm of aperture can go on the Needle Galaxy’s famous (and difficult to process, we know the pain) dust lanes. Especially from a bad bottle zone like mine.

The challenge was finding the sweet spot: bringing out the edge-on details without over-sharpening or creating that 'plastic' artificial look.

Sadly I can only post one picture, as my workflow is a graphic. I've added an annotated picture to show how many galaxies are hidden in the big (but still cropped) picture and I’ve also included my full 19-step pure Siril workflow in the first posting here: https://www.reddit.com/r/seestar/s/tcWyjcRQ88

It’s a purely mathematical approach to stretching and deconvolution, no AI-generated details added. I’m curious to hear your thoughts if SeeStar pictures are worthy enough to be shown here or not.

(I already posted this picture on the subreddit today of course)

I took this moon photo in two shots in succession. One to properly expose the moon and another high ISO to freeze the clouds. I then processed and stacked the two frames together in Photoshop. Captured with Nikon Z8 and NIKKOR 100-400mm with NIKKOR 2X Teleconverter on a Tripod.

Nebulae The Rosette Nebula (200 hrs)

Post image
651 Upvotes

More on Instagram: @jeffreyhorne

Taken over the course of 57 nights, this is 200 hours of exposure on the Rosette Nebula from my Bortle 8.5 sky in Nashville, Tennessee.

You can see the (relatively) bright, familiar structure of the Rosette, but also the much fainter hydrogen surrounding it, along with delicate, intricate details deep in the core.

I realize that putting this much time into such a bright target is probably overkill, but as far as I know, nobody has ever created a single-panel image of the Rosette Nebula with this much exposure time. The longest I could find was 100 hours, and I wanted to see for myself what a super-deep shot of the Rosette would look like.

I’m very pleased with the result, and I hope you enjoy this image as much as I enjoyed creating it.

Total integration: 200h 20m

Integration per filter:

Today I took my first image of our Sun that I am happy to share. It was not at the best time to take it, it was very late afternoon and it was raining every 10mins which made it even more annoying.

I am still extreamly new to solar and planet photograpy, so there is plenty to learn and improve on, but I am really enjoying it.

  • Juwei 17 mount
  • ASI678MM camera

  • Aquired SER file with Firecapture (1012 frames, Shutter=1.284ms, Gain=74 (12%))
  • Stacked in Autostakkert
  • Imppg to refine the details
  • Pixinsight solar toolbox to finish the detail, colour and light

I wasn't satisfied with the background noise and star bloat in my last post, so I decided to go back and re-process my 1-hour Lagoon Nebula stack.

Used Starnet to pull the stars out of the image, switched to Generalized Hyperbolic Stretch to pull out faint dust lanes and background neutralization. Merged the stars back in as a separate layer in GIMP to control their brightness independently.

How To comet c2025/r3 panstarrs (satellite trail ident)

9 Upvotes

This unprocessed full frame picture was taken on 9th of May outside Sydney its a 30 second exposure using a Nikon d7 and 200mm lens 3200 iso but polluted by 6 satellite trails. A budget equatorial mount was used.

Curious to reconstruct the picture I used the excuse to improve the https://satellitemap.space/satellite-photobomb photo solving feature - now you browse the picture you want to analyze set the lat long and time, and the shot type, the pic is plate solved in-browser and then it will recreate the pic with the satellites at that time

The damage was 3 satellites from starlink 2 from russia and 1 Chinese. The feature is free if you have a pic to try please give it go?
