Calibration Recommendations

 

The Mini-Mosaic is, at this writing, brand new. You certainly won't go wrong if you obtain 10 biases every night, and 5 dome flats through each filter (aiming for a count of 20,000e each, or 30,000 ADUs, say). We believe that this will then flatten your data to better than 1%. If you want even better flats, you will need to use dark-sky flats.

The following table gives reasonable lamp settings and exposure times.

Filter High Lamp Setting Exposure Time
U 3200 15sec
B 2500 3sec
V 1500 4sec
R 1000 1sec
I 1000 1sec
