Electronically Assisted Astronomy (EAA) uses cameras take images through telescopes and display them on a screen. Software is used to stack multiple images over several minutes to build a picture and unlike astrophotography takes only minutes to display. The goal is to see fainter objects can we can see with our scopes and to allow us good viewing even in the city. We have quite a few members working on EAA. Here is a gallery of sample images to see what can be accomplished.
Bode's Nebula, M81 & M82
Bode's Nebula, M81 & M82 are not nebulae but are galaxies. John Bode, who found them in 1774, described it as a nebula and the name stuck. M81 is the larger spiral galaxy in the middle of the frame while M82 is the smaller, edge on galaxy. M81 and M82 are relatively close together at 150 light years between the centers.
