Andromeda Galaxy

Using the Bradford robotic telescope I have begun experimenting with using different filters to see how the results vary. Here are the results of one recent session photographing the Andromeda Galaxy

BVR is the standard colour filter

H-Alpha filters block all light except that given out by Hydrogen atoms emitting energy. Interestingly here the only source of light is in the very centre of the galaxy.

I am semi-retired after a career in medical sciences. I now work from home doing independent research and consultancy amongst other things. One advantage of this is that I do have time to indulge my interests including birdwatching, natural history, steam trains and history particularly ancient history.
