Description

Even a well corrected lens like the sigma art 40mm has some issues at the fastest aperture. I will revisit this area, but stop it down to about f2 next time. The challenge with mosaics is that the stars in the corners are badly distorted on a wide angle lens, which makes it hard to register, and when you do, the line is obvious because of the change in the fine grain of the star shapes.
On the left, the Vela supernova remnant is just visible, and the milky way from Vela all the way across to Centaurus is a magnificent sight in our summer sky.
