Description

M104 has the highly coveted distinction of being the lowest altitude galaxy imaged from my backyard, with an average altitude of 24 degrees above the horizon. The image itself is a combination effort from myself and the then Sierra Obs. in Nevada. The luminance data from the latter was seriously compromised by very poor flat and noisy (just 5 min. of exposure albeit with a 50cm Cassegrain) but with much better resolution and the image from Lincoln was compromised by the general poor seeing at those altitudes. The combined luminance has been made balancing the total photometric signal from both integrations. Colour data is from Lincoln as well. This so characteristic galaxy is certainly in my list of objects that needs a second try, though I somehow doubt it is going to happen in the near future. Maybe when I'll move to a more southern location but who knows...
