I'm still fairly new to astrophotography and I enjoy it a lot! Had some time a few days ago to image Barnard's Loop. My exposure time was limited because my trip was a last second decision as I had work the next morning. Overall, I'm very happy with my picture.

 

Equipment:

• iOptron Skyguider Pro
• Canon T3i (modified)
• Canon 50mm f1.8 (Stopped down to f2.8)
• Bortle 4-5

Frames

• Light frames - 63 x 1 min
• Bias frames - 20
• Flat frames - 20
• Dark frames - 5

Processing

• Stacked in Siril and used autostretch + background extraction to help remove gradient
• Photoshop
  • Curves adjustments
  • One or two arc-10 curve adjustment presets applied
  • Stretches
  • Slightly cropped
• Starnet++ to help remove some stars, then the image was blended with the original curved/stretched starry Barnard's Loop

My apologies, I had to upload it first since it looks like the upload file under post didn't work but it should be there now!

Great shot. I would raise black level just a bit, otherwise perfect.

Really nice work.

I am always amazed by shots like this.  No nebulosity is apparent to the naked eye, unless you consider M42 which was probably 'mistaken' for a star since Adam and Eve, but collect photons over time and all the nebulosity becomes obvious.  Just goes to show you that empty space isn't empty space.

That's great, I really love wide angle shots... There's just such a huge variety of objects the gigantic Orion Molecular Complex, I really want to attempt a widefield mosaic on it someday. You did a really good job getting the 50mm to behave, that thing is no joke to get properly focused for astro work...

Nice shot. You even got the witchhead in there.

Very nice capture!  I don't recommend using autostretch in Siril to perform the stretch of your image.  This is just a preview mode.  You'd bring out a lot more color using Asinh Stretch.
