![]() My latest version of the Swan Nebula Selective Processing You can also manually Remove the Stars Completely from your image using photoshop. This actually starts to diminish the precious detail in your deep-sky object that you worked so hard to capture! Many other actions that are intended to correct issues with the background space and stars can take away from your subject as well. Normally, I would run the “ make stars smaller” action to the entire image in Photoshop. For example, I can boost the vibrance and saturation of the nebula or galaxy without adding additional noise to the background of space and stars.Īs I have stated many times, I prefer to tame the stars in the image to be as small as possible. I am able to do this by selecting each element of the image and stretching the data without affecting the other areas. By this, I mean to process the background, the stars and the nebulosity on their own. One of the processing techniques I have been implementing into my photos is to process different elements of the image separately. Wide field image of the Eagle Nebula with my 80mm telescope Image Processing Techniques By reducing the stars on a separate layer, I was able to keep all of the detail found in the nebula. This image really benefited from the selective processing technique. I decided to keep the extremely wide-field view captured by my 80mm telescope, rather than cropping the photo around the nebula. I combined all of the data together from May 2012, and May 2013 in DeepSkyStacker to create an image with over 3 hours of exposure time. I went through my astrophotography folders from the past 4 years (like I said, it’s been cloudy!) and found a set of almost 2 hours of frames on M16 that I had not previously used! I am quite pleased at my latest results of the Eagle Nebula as well. After assessing the gradient in Photoshop, (mostly due to heavy light-pollution) I can easily even out the sky background using the Gradient Xterminator plugin. The “witch’s broom nebula” is a tough process, especially if you have to deal with a severe gradient behind all of those stars. I also recently reprocessed my wide-field image of the Western Veil Nebula, with a focus on reducing star size, and overall image contrast and color. Through selective processing, I was able to tame the background stars, while intensifying the gorgeous pinks and reds in the nebula itself. My latest take on The Swan Nebula is my favorite version yet. The Western Veil Nebula – I reduced the stars to show more contrast in the nebula Through selective processing, I have been able to squeeze out the most amount of detail from my astro images. I have been advancing my image-processing skills by studying current astronomy images taken by the pros.īeing a creative professional myself, I have always understood and appreciated the power of inspiration. I am always interested in new image-processing techniques, Photoshop tutorials and new software that can enhance my work. The unseasonably cold weather and precipitation we have experienced here in Southern Ontario have given me the perfect opportunity to go through my old astrophotography images and reprocess the data.
