COMMENTS
This was my first experiment imaging with a barlow. Little I knew that
by multiplying by two the focal ratio, the time to gather the same
amount of light and detail increases by a factor of 4 (aprox). So there
I was taking just a few short 6 minutes exposures on the Sombrero galaxy,
which was also pretty low in the horizon.
In any case, this is a beautiful object I will definitely revisit again when
it's again well positioned in the sky next year.
