More Weirdness from Ursa Major
Ursa Major is full of strangeness. For example, M82 - the exploding galaxy, or NGC 2976 - the spiral that is not a spiral. This image is of another strange galaxy. It is NGC 3077, thought to be an elliptical, but classed by some as an Irregular. At first glance it looks like a typical elliptical galaxy, but look again. There are dust lanes and tendrils in it very similar to the ones seen in M82. Conventional wisdom tells us that Elliptical Galaxies have no dust or gases, and are simply large oval clusters of stars. The accepted knowledge says this galaxy should not have these dust lanes, or whatever they are. However, we do not make the rules. Here is an elliptical which apperantly breaks our preconcieved notions of these objects.
My image does not do it justice. I had some problems with the bright star flaring on the main lens of my scope, and making a big ugly smear or two right above the galaxy. I took this image with my ST7 and 6 inch sct. It is 9 thirteen minute images median stacked and deconvolved.
