Description

This is a composite image taken with my "dual rig" with a Canon 300 mm f/4 telephoto lens sitting side by side with an ES 127ED apo refractor. Data of the refractor image has been added to the trunk region of the nebula. I also posted the refractor image separately.

I am quite pleased with the optics of this telephoto lens, which at full opening (as in this image) shows no coma in the corners. ISO set at 1600 and seeing was ok and SQM = 21.1.

In version C I have just fixed a bit with the stars for pixel peepers
