There will be two member presentations at the next meeting:
“Comparison of Focal Length, Filters and Processing” by Dr. David Elmore. We have seen many artful images of deep sky objects posted by Longmont Astronomical Society members. Often we image the same target but with telescopes of different focal length, different optical filters, and then use different processing. Concentrating on images of the Cygnus region I will present examples and discuss what make the images different.
“All Sky Camera Control System” by Vern Raben. Our new camera will contain its own Raspberry PI3 processor to capture and transmit images to the LAS website. Vern will discuss camera control utilizing publish/subscribe messaging. The control messages are transmitted using websocket protocol which may be used with normal web server connections. This technolgy enables the camera to be securely controlled locally or remotely using web browsers, cell phone apps, or desktop programs.
