Caldwell 14 Double Cluster in Perseus
Photo description / processing
The last photo with the CAA; today I removed it from the optical train because it still introduces a tilt that isn't noticeable on a small sensor, but with a larger sensor it's obvious. Now we'll manually adjust the required angles; it's a shame because it's a good piece of equipment, but you still have to keep an eye on it—it might act up. In any case, everything that happens, happens for the best.
