Image sets 1-3 were stacked using darks, bias and flat calibration/support frames. My modified Canon T3i camera was set to ISO 800 for each imaging session, but I bumped the exposure time up to 3.5 minutes for the fourth and final set. The photo sets from each imaging session were loaded into the group tabs of DeepSkyStacker. Yes, it is very white! That’s light pollution for you. This winter has been plagued with numerous cloudy nights, so I had to capture photons here and there, under varying sky conditions. ![]() The screenshot below shows the results of registering and stacking 4 nights’ worth of imaging from my backyard. We’ll start with the Autosave.tif file produced by DeepSkyStacker after registering, stacking, and calibrating my sub-exposures. The data should like quite similar to anyone capturing the Orion Nebula using a DSLR camera from the city. Some of the images used in my final photo were shot during the AstroBackyard YouTube video: Let’s Photograph the Orion Nebula. I will be incorporating 2 hours and 40 minutes of Ha ( narrowband) data into the final image using the HaRGB processing technique. The total amount of detail I was able to capture on the Orion Nebula and Running Man Nebula this winter was 3 Hours and 8 minutes of broadband, color RGB data. If you’re looking for more options, be sure to see my complete list of the telescopes for astrophotography I recommend. The telescope used for this photo was an Explore Scientific ED80 APO refractor. The newer Canon Rebel series DSLR’s (such as the T7i) are also a great choice. 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. The winter astrophotography targets in the Orion constellation will have to wait another year to get photographed. This step-by-step tutorial should be useful to anyone processing a bright nebula with Adobe Photoshop.Īs we transition into spring, a new array of deep-sky imaging targets will present themselves. 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. ![]()
