I was at ISO 400 to your 200, and f/5.6 to your f/4.0 — so those cancel each other out. You gave approximately 3 stops more exposure than I did. I was shooting an hour and a half after sunset, and closer to civilization than you, so I expect that gives me a somewhat higher level of ambient light, perhaps a stop's worth. My image was (deliberately) underexposed by a couple stops so as not to blow out the stars, and then brightened in post, so that accounts for the rest of the difference. Here's the resized-but-unaltered RAW:
How does that compare to your unprocessed RAW? |
My resized-but-unaltered RAW:  I agree with your comparison analysis. |

(it must have been pretty dark there for such a long exposure at f/4. compare that with 180s in Robert's shot with f/5.6... and also moonlit, presumably by the same moon :)... do you understand it?) |
No, not entirely! I was shooting after the end of astronomical twilight. It was very dark. Maybe Robert had some twilight left.... or light pollution from civilization on the East coast. The ONLY source of my light was the waxing crescent 24% moon. Had I used 180s, I would have had very little exposure. Mystery to me! I could not see the light pollution from Fort Collins, but it registered on the sensor. |

Bedded Down under the Starsby hahn23Comment by Dennisheckman: Very well done Richard. Can't for the life of me figure out how you could get anything less than a 6 on this. I think it's due to maybe voters think this technique is supposed to be easy or something. Anyway, congrats on an outstanding image, I knew this was yours the second I saw it! Outstanding effort with going out in the middle of the night to do this. |
