In reply to Nicholas. This picture was taken over two days because I took images using a hydrogen-alpha filter on one night, and then clouds prevented me from continuing. So, I came back a few nights later and took additional images using sulfur II and oxygen III filters. These three filters comprise the so-called "Hubble palette" that is frequently used by the Hubble Space Telescope. I am not familiar with stereoscopic 3D imaging of the heavens, but I will look into it. Sounds interesting!

I work with your son in Dalian, China, and he told me about your website. As I was looking at the details for this image, I noticed that the image was taken over the course of a couple days. This got me thinking about the nature of 3D photography. Basically two shots of the same “event” are taken from two different angles, and the results are combined either by crossing your eyes or by using a 3D display and some glasses. I was just wondering if you have every created any photos that might be viewed in this fashion? I have my doubts that 2 or 3 days would provide enough of a difference in viewing angle to provide any discernible depth. Do you think something like this would even be possible given the distances we’re talking about?

Amazing image, very beautiful and nice colors. You are very good astrophotographer and i like natural look of your images. As amateur astrophotographer i know how much work you need for making one image.
