This picture simply uses our Sigma 150-600 mm lens and at FL 400 mm one can capture the entire nebula. Finding the correct adaptors to allow my camera and zoom lens to use the tracking mount opened up all sorts of new possibilities to frame nebula many of which are very large. Using a combination of the telescope and zoom lens we can cover 150-800 mm. Some day getting a telescope with even longer focal lengths would be great to get in closer on galaxies and planetary nebula.
