There is an AWESOME web-extra over at SkyandTelescope.com all about the efforts of 2 of the staffers to image the Orion-Eridanus superbubble from suburban Boston.
The story and technique information is great but the images are absolutely astounding. They require that you zoom in and pan around the various parts to see all the amazing details of these very familiar areas in our night sky.

You can see the massive amount of interstellar gas spread over this vast area. It is unbelievable what amateur astronomers can accomplish in this day and age. Citizen scientists indeed. Very impressive work by Dennis di Cicco and Sean Walker.
