|Galaxy M94 in Canes Venatici
M94 is a bright, compact spiral galaxy with four layers of structure. The smallest of these is a central bar. Surrounding the bar are densely wound arms,
with very rapid starbirth in the inner regions of the spirals. The third layer includes the outer arms, dominated by yellow and red, older suns, where
earth-like environments are more likely. The fourth layer is the extremely faint outer halo of stars bound more loosely to the galaxy. M94 resides 15
million light years away, and is much smaller than the Milky Way, spanning a width of only 30,000 light years.
This image combined 65 minutes of luminance with 20 minutes each of red and green exposures, and 30 minutes of blue. An ST10-XME CCD camera,
with an AP 0.67x nosepiece reducer, was used through a Meade 12" LX200R on an AP900GTO mount, at the Hidden Lake Observatory
