This is my first test of iOptron SkyTracker. Orion Nebula M42 is in the list of top 10 deep sky objects for amateur astronomers. So I choose it for first test. I tried exposer 15 seconds. For fixed tripod with Canon Telephoto Lens EF 200mm f2.8 L II USM it gives star trails. With iOptron SkyTracker even without precise alignment stars looks like points. Weather was good but NYC light pollution, plus it was 3 / 4 Moon near Orion nebula. So I use small ISO (Urban astrophotography). There are results:

| M42 Orion Nebula one single file from NY City |
Canon 60Da, Canon EF 200mm f/2.8 L II USM Telephoto Lens, Exposure 15 sec; f/2.8; ISO 320, New York City
Using DeepSkyStacker stacked multiple images. Every Canon Row CR2 image first updated in Canon Row 7 saved as Tiff file and later stacked in DeepSkyStacker. Post processing after that was done in Photoshop.

Final Thoughts
Capturing deep-sky objects like the Orion Nebula (M42) from Brooklyn, New York City—a location with some of the worst light pollution in the world—is normally very challenging. In NYC, even bright stars are often barely visible to the naked eye.
Yet with a tracking mount and 204 stacked exposures, it’s possible to overcome heavy urban skyglow and reveal nebula details that most people only see from dark-sky locations.
This project proves that urban astrophotography is absolutely possible, even under strong New York City light pollution, when you combine good technique, accurate tracking, careful stacking, and thoughtful post-processing. Anyone with patience and the right workflow can capture real deep-sky images—even in a city that never sleeps.
