Remove Gradients in Your Astrophotos with Photoshop
Adobe Photoshop is the preferred weapon of choice for many astrophotographers of varying levels of experience. The intuitive user interface and limitless image processing capabilities make it a real contender in the astrophotography world. The seamless integration with the .RAW image files produced by a Digital Camera makes Photoshop an attractive choice for photographers using popular Canon and Nikon DSLR's. I have included a section on gradient removal in my premium astrophotography image processing guide for those interested. It continues to be my personal favorite tool…
Deep Sky Image Processing in Photoshop
Well, this is it. In this deep sky image processing tutorial, I'll be combining all of the data I was able to collect on the Orion Nebula this winter. As we transition into Spring, a new array of deep-sky imaging targets will present themselves. The winter astrophotography targets in the Orion constellation will have to wait another year to get photographed. The camera used for this image was a Canon EOS Rebel T3i (600D), an excellent choice for beginners looking to dive into deep sky astrophotography.

Manual Stacking in Photoshop for Reduced Noise
Even without a tracking mount, your astrophotography images can benefit from manual stacking in Photoshop. This method involves aligning exposures and combining them into a master composite. It can make a big impact on your astrophotos by reducing noise and improving the signal-to-noise ratio. The images used in the example were captured using a camera lens in place of a telescope. A wide-angle lens can be a tremendous way to photograph a large area of the night sky at once, rather than zooming in on a deep sky object. [caption id="attachment_4045" align="aligncenter" width="7…
Screen Calibration
When I purchased a new laptop computer back in 2016 for image processing and video editing and was quickly reminded of the importance of having a well-calibrated computer monitor. The brightness of my new laptop screen was intense. It appears to be about 25% brighter than my well-calibrated 23 Inch external IPS monitor. When it comes to editing and viewing astrophotography images, the screen you're using can really change the appearance of your results. If it's too dim, you may not see all of the hidden imperfections in your data. This results in astrophotography images that ar…
