Yeah if the smart scope is just doing all the work and spitting out an image on its own that’s fine. Generally as long as you include any kind of info about your processing steps it’s fine, and you can have it be as brief or detailed as you want (I know mine are on the longer side).
Personally I’m all for more detail = better. It’s a lot easier for people to give constructive criticism, and a good enough writeup can serve as a guide for those just learning how to process (and I’m always going back to my old posts just to remember how the hell I even processed a tricky image)
Hi OP can you include acquisition/processing info per rule 5?

Sh2-64 is the red nebula to the right of the image. It frames up pretty well with the more golden stars seen in the milky way core. I probably should’ve gotten more exposure time to help bring out some of the dark nebula details, but it was only clear for one night at the dark site (at least the night went perfectly, which is rare for trips out to the middle of nowhere).

Omega Centauri is the largest globular cluster in the sky and contains about 10 million stars, but it’s generally considered a southern hemisphere target since it’s at -47 declination. It was right at the meridian for me while waiting for it to get completely dark out, so I tried shooting it at just 9 degrees up. Had to do short exposures without guiding, because even the dim flashlights of the other campers with me would overwhelm my guide camera.

Wasn’t expecting much with the last night’s geomagnetic storm, but seeing the aurora come in on the camera was definitely an “oh shit” moment for me and my wife, especially when it got overexposed. The initial burst in the gif was very noticeable to the naked eye, despite our light pollution. Sadly it died down a bunch, but seems to have come back (although not as strong) after 3am (video timestamp is in UTC). Tonight definitely wont be as strong, but I’m hoping the camera might pick something up on another timelapse. Captured on May 10th, 2024 from Atlanta, GA
(probably) Better quality version on youtube

Definitely the lights. I got them in Atlanta too
Hi, OP! Please include ALL acquisition and processing details
Was any processing done to this?
Could you edit your equipment out of your title?
Also any and all astro photos are allowed here, regardless of how “low effort” they are (as long as they follow the couple rules on the sidebar. I don’t want there to be any kind of arbitrary minimum quality standard to prevent people from posting their space photos on here.
Finally done with classes and I got some time to at least star processing my pics. Gonna be a while before I figure out all the HDR stuff, so here’s a pic of the prominences about 10 seconds before C3. It was absolutely nutty seeing them naked eye during the eclipse, and visually through my other telescope. Captured on April 8th, 2024 from Sikeston, MO.

Hi OP, this community is for amateur/original content only, not professional photos.
Thanks to my north facing balcony, I can only photograph the moon when it’s at high declinations. Fortunately it was at +27 dec the other day, and it was early enough for me to be awake to shoot it! Captured at 10pm on April 12th, 2024.

This is an animation of every 1/4000" frame I took during/around totality. For most of totality I was looping HDR sequences and had one of these frames roughly every 15 seconds, but around each contact I bursted these short frames to get the beads. The animation lasts for the entirety that my solar filter was off, which was about 13 seconds before/after each contact. I think it’s cool seeing the motion of the moon relative to the sun like this. Since imgur compression is kinda shit, here’s a (slightly) less compressed version on youtube.

Which phone cam did you use?
I’m guessing it’s called that because it’s kinda headphone shaped. It was discovered in the 30’s so I’m assuming only the brightest parts of the nebula were visible to the astronomers.
This image is a combination of false color narrowband images for the nebula itself, plus true color RGB stars (the nebula is mostly red and a little blue in true color). If you zoom in to the center you can see the very blue white dwarf that caused the planetary nebula to form. Also for those curious this is what a single 10 minute long Ha exposure looks like (image total is 83.5 hours exposure). Captured over 33 nights from Jan-May 2024 from a bortle 9 zone.
