Here about 300 hours of integration of unfiltered images taken until winter 2024, exclusively with telephoto lenses and DSLRs.
This image offers a good overview of the main structures on the disc and the external halo of Andromeda (M31).
The external halo presents various irregularities and thickenings that we can consider as debries of dwarf galaxies progressively incoporated by the greater galaxy, as foreseen by the growth models.
M31 is thought to have assimilated a few hundred small galaxies or globular clusters.
This process is still ongoing.
For a description of the structures in the halo, please consult this figure: flic.kr/p/2iyoMJ2 and this flic.kr/p/2oBr9aA
Scientific data are available on request for serious galactic archeology studies.
I think I can't do more with a process that is honest and reproducible by anyone without any artifice: just calibration and stack. I can declare the DAGAS-2 deep survey of the M31 and M33 haloes completed. No sign of recently mythological beasts.
