Description

Another try at the Pinwheel, this time at a higher ISO, and with more and longer-exposure frames.  A modest improvement.

Getting better at using the polar drift alignment in PHD. When all else fails, read the instructions!

But as I said on the previous try, I think I'm bumping up against the limitations of my current setup's capabilities.
