What is drizzle in Deep Sky Stacker?

​Drizzle is a simple algorithm that creates an image that is larger than the images in the stack and interpolates between pixels to ensure it reproduces fine detail in edges despite the effects of stacking transformations. The former generates a final stacked image that is twice the size in each dimension.

What is a good score in Deep Sky Stacker?

When stacking the photos in DSS I see always that one scope always has higher scores than the other. The numbers range from 3500’s to 6500’s. The better scope shows high numbers in the 6500 range and the other has high numbers in the 4600 range.
