Sep 15, 2010 12:36 | #4 I did a bit of editing to remove the light pollution and the noise a bit. How does this look?  α7R IV | Σ 24-70 f/2.8 | Σ 150-600 f/5-6.3 | Σ 14-24 f/2.8 | 1D MkIII | 430EX II | 24-70 f/2.8L | 70-200mm f/2.8L IS

Sep 16, 2010 09:23 | #6 Yeah, the edges got a bit wonky when I removed the light pollution. I'm going to try again tonight if it's clear. α7R IV | Σ 24-70 f/2.8 | Σ 150-600 f/5-6.3 | Σ 14-24 f/2.8 | 1D MkIII | 430EX II | 24-70 f/2.8L | 70-200mm f/2.8L IS

Look at the high side of the curve and make sure you can see *all* of the curve. If the curve disappears off the top of the graph because of a sharp angle then play with the 'high' angle to bring the curve back within the visible graph. Something goes wrong in DSS when the curve is too high.

I highly recommend these tools if you want to get into astrophotography at all. This was 2 minutes work at max.  IMG NOTICE: [NOT AN IMAGE URL, NOT RENDERED INLINE]
