Second test of my L-Ultimate: The Crescent Nebula

[Smiller]

For my second test, I caught the Crescent Nebula with about 4 hours of 8 second exposures.  I’m limited to about 8 seconds since I’m just using my unguideD Alt/Az Goto Dobsonian sitting on a piece of plywood on the lawn.

This filter is a keeper, even with my super short exposures.
