Cepheus Mosaic

Here is a 2 panel mosaic from the constellation Cepheus. I wanted to frame both the Bubble Nebula (far left) and the Cave Nebula (far right) into one composition, so this forced me to shoot two different fields and blend them together into this mosaic. It was a lot of work, since I shot separate passes for L, Ha, R, G, B, and then not only did these pieces need to be registered, but also matched in terms of exposure (which can vary because of angle in sky and high clouds, etc.). But I am very happy with the end result.

There is so much to see in this field -- red emission nebulae, dark nebulae, reflection nebulae, dust, etc. Sometimes these images remind me of abstract surreal art by artists such as Tonguy, Matta, or Richard Powers (I am a huge fan of these artists).

This image represents about 9 hours of exposure last week at the 3RF astronomy campus.

Awesum pics. I want to click such pics. May I knw which lens you are using. And What was the duration of exposure ? And do you have to move the position of the camera considering the earth's rotation if the exposure is more than a minute
