Bode's Galaxay (M81)

Discovered by Johan Elert Bode in 1774, this "grand design" spiral galaxy is located about 12 million light-years away in the constellation Ursa Major. Its large size and relatively low apparent magnitude (higher brightness) makes it a good target for my telescope.

Two amazing images of Bode's galaxy are: (1) a image taken by the
Hubble Telescope and an 2005 infrared image of M81 by Spitzer Space Telescope.

M100 Coma Berenise

A beautiful example of a grand-design spiral galaxy, and one of the brightest galaxies in the southern part of constellation Coma Berenices. M100 is a spiral galaxy, like our Milky Way, and tilted nearly face-on as seen from earth. It is among the first spirals that have been discovered, and listed by Lord Rosse as one of 14 "spiral nebulae" discovered to 1850. The galaxy has two prominent arms of bright blue stars and several fainter arms. The blue stars in the arms are young hot and massive stars which formed recently from density perturbations caused by interactions with neighboring galaxies which are lying just outside our image. Despite its nearly perfect symmetric outline, this galaxy appears slightly asymmetric, as on the southern (lower) side of the nucleus more (or brighter) young stars have formed.
