M95 & M96 Spiral Galaxies + M105 Elliptical Galaxy

NGC3384 - NGC3373 Galaxies

Leo

Mouse over the above image for galaxy catalog identification

Spiral galaxy M95 is on the left at magnitude 9.69 and M96 is near the middle top and is listed at mag 9.30.  The brightest, round galaxy on the right is elliptical galaxy M105 at magnitude 10.1; lenticular galaxy NGC3384 is to the right of that at magnitude 10.7, and above that is the bluish spiral galaxy NGC3373/NGC3389 at magnitude 12.4. 

The Leo I Group is a collection of galaxies who's members, with the exception of NGC 3373/3389, lie at common distance of around 32 million light-years and share a common red shift. NGC 3373/3389 lies at twice that distance. There is a second nearby galaxy group in Leo at a similar distance - the better known Leo Triplet.  Mouse over the above image for object identification. North is to the right in this image.
