Celestron C11-HD with reducer on unguided CGEM , camera was STF-8300M. Stack of 19 ten second exposures.


I wondered what the star looked like before the outburst. An example of the power of computers is shown by displaying a photo of Nova Del 2013 in Microsoft's World Wide Telescope. Amazed to see how exactly the new photo overlaid existing data. Cross-fading, the stars don't move the slightest, showing the precursor star. My page showing the nova overlaid on the pre-nova star (magnitude 17) is (with how-to links) is at: http://www.flickr.com/photos/edhiker/9542094841 Ed Johnson (edhiker)
