Astronomy Project Results

Here are the fruits of a semester of work to attain a CCD image of the spiral galaxy NGC 3198 in Ursa Major at my school's observatory:

Raw image


Median filter


Reduced image in blue filter


False colour image showing structure


I think the false colour image best illustrates the spiral, yet intermediately ringed structure of this galaxy, not to mention you get a better feel for the bar in its nucleus.
