SVX140T - M80

Larry Ammann captured this striking shot of M80 (NGC 6093) with his SVX140T. According to Larry: “M80 is a globular cluster in Scorpius that has attracted the attention of professional astronomers due to its relatively large number of blue stragglers. These massive stars should be much younger than the cluster itself, and so they indicate the presence of interactions and collisions in M80's dense core. M80 appears small here but that is only because it lies on the opposite side of the Milky Way's center from us. As a result, its light passes by clouds of gas and dust around Rho Ophiuchi and IC 4603. These reflection and emission nebulae contain some of the closest star forming regions to Earth, with a distance around 450 light-years compared to M80's distance of 28,000 light-years.”
