Description

This planetary nebula is very bright and hence called for short exposure approach.  It's also so tiny that, even in a small sensor like 585, it needs a crop/zoom for us to see its turtle-like shape.  Exposures of 5 seconds leave a lot of read noise in the stack and can affect star quality, but it didn't turn out too bad in the end, after processing.  One key reason was dithering every 20 frames to eliminate the walking noise.
