This scientific grade image is the result of the combination of a large number of shots taken at different times and with differrent instrumentation. Mainly with 200-300mm telephoto lenses and DSLRs but wide-field shooting with CCD and short-focus apo refractors are also included.
Being primarily interested in the stellar content of this galaxy, the images do not include narrowband captures. This has allowed us to attribute what some believe to be interstellar dust clouds to true stellar clouds and tidal structures. These structures are in perfect agreement with studies of the halo of M31.
