Science observations completed. First attempt produced 4 good images, but had to be stopped due to weather. Second attempt successful - completed the OB (from the start), but the very last exposure cut after 60s instead of 100s, again because of weather.
Std. star missed due to weather. |

Target and standard observed with clear skies and seeing around 1.4" for target.
In the future, please include the tcs.asteph command in the comments of the OB.
This helps us do the observations according to your wishes.
I used tcs.asteph -t comet -m ima -n 2025 R2
I hope these were the preferred parameters. |

ALJa160109 - ALJa160123 |
Observed in clear skies and varying seeing from 1.5 to 2.5".
For 2025 K1, the initial guide star was at the edge of the area of the guide probe so when using the command from asteph to reposition the guide star box and starting the exposure, warning "Guide probe will vignet. Doing telescope offset but autoguiding is lost" came up and the guiding stopped. I found a workaround by selecting another guide star with enough space for the guide probe to move. |
