M 16 - The Eagle Nebula
From the author of Welcome to the Universe in 3D
02:30 EDT July 15, 2026.
Seestar S30 Pro at f/5 in Equatorial Mode.
175 minute stack of 20-second subexposures executed using the M16_better Plan.
Here's some details about the image processing: I loaded the stacked fits file into PixInsight.
In PixInsight I used NoiseXTerminator and then BlurXTerminator to improve things a
bit.
I then saved the updated fits file and used the GraxPert app to correct for the gradient in the background.
I saved the improved file as a tif file and then loaded it in
Photoshop were I used AutoTone and Curves to brighten up the nebulosity.
