| Conditions: | Clear but fair seeing |
| Scope: | RCOS 12.5 Truss |
| Camera: | ST-10XME/CFW-8A -20° |
| Comments: | The skies were clear, good transparency, seeing was steady. The 12.5 RC was on loan from Greg Morgan and my ST=10XME was a good matchup for the skies at SRO. More data collected than the other attempts and the results show the differences. The longer you can go the more data you have to process, but better results are the rewards. |
