In this post, I’ll walk you through the image processing steps I used to create the image of the Andromeda Galaxy shown below. This astrophotography tutorial uses Adobe Photoshop to bring out the intense colors and detail of a galaxy that was photographed using a DSLR camera and a small te...
Compared to photographing deep-sky objects, like galaxies and nebulae like I normally do,photographing planetsis a breath of fresh air. I am not a planetary imaging expert by any means, but I will share the simple steps I used to get results like the one below. The process involves recordi...
IN ASTROPHOTOGRAPHY, it can sometimes be difficult to see the forest for the trees, Extended nebulosity within the Milky Way's dense star fields can often be obscured by the sheer number of bright stars in the area. Stretching an image to bring out this colorful gas also increases the outer...
I don't own a computer, so all of mine are either straight from the Seestar or processed through either Photoshop Express, Snapseed or AstroEdit. Since the Seestar is my first ever step into imaging/EAA, having been a visual only observer for the better part of 30+ years, I am mostly...
Light pollution and airglow are added light, so it is proper to subtract it if one wants to remove it to reveal the beauty of deep space objects like galaxies and nebulae. First remember that this method of using a standard raw converter, and applying a tone curve has many advantages, ...
Topaz DenoiseAI has been my goto processor when needed for galaxies and nebula. I usually have original and noise reduced images saved. It is unfortunate that I can't find a command line way to run the program. Then it could be patched up with a folder monitor script to make it part ...
Nebulae and galaxies are much less bright than the brightest stars. In astrophotography, it is the dark part of the image that we want to highlight. The “tone stretching” allows for emphasis the dark tones compared to light tones.

Here is a crop of the galaxies themselves. Leo trip crop.jpg I've used Photoshop, Startools, Pixinsight, and AstroPixelProcessor before. There's a reason I keep coming back to Pixinsight. In my opinion, the versatility it offers is unrivaled when considering software for processing astronomic...
The tooltips for Jocular stretches used to identify the DSOs that a particular stretch would be suitable for. That said, I sometimes find myself using, for example, log stretch for galaxies with bright, detailed cores. The added auto-whitepoint feature has changed my preferences too. If you...
