imaged NGC 6210 faster (Halifax)

I continue to struggle with imaging planetary nebula. They seem to be incredibly bright and exposure times used for galaxies, 60 seconds, 30 seconds, are not appropriate.

I asked BGO to reshoot the Turtle Nebula for me. One-third the speed of the first go-round. It complied. Sadly, I still cannot see the central star...

Luminance only, 10 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; left is east.


The original post said 60 second subs when in fact they were 10.
