Remove Gradients in Your Astrophotos with Photoshop

|Tutorials|7 Comments

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. It continues to be my personal favorite tool for processing astrophotography images. Whether you are brand new to astrophotography image processing, or a seasoned vete…

Better Focus using a Bahtinov Mask

|Tutorials|7 Comments

A Bahtinov mask can help you achieve a sharp focus for your astrophotography images. This process is an essential step of any deep-sky astrophotography session. With so much time and effort put into your polar alignment and autoguiding accuracy, it would be a shame to spoil a photo due to poor focus. Over the years, I've had my fair share of deep-sky astrophotography focus mishaps. In many cases, I did not realize how bad the focus of my image was until I attempted to process the final image. You can avoid this unfortunate circumstance by using a simple tool that effectively confirms…

Manual Stacking in Photoshop for Reduced Noise

The images used in the example were captured using a camera lens in place of a telescope.
