The rms dispersion of the image average without overscan calibration is 1.164 ADU and with it is 0.376 ADU. The overscan calibration uses the...
After upgrading stf-8300ga.bf2 from version 2.24 to version 2.25, I took 100 Bias frames with no anomalies and then 1000 more, also with no...
Bias_100 has a normal average of 1041.62 and an rms of 28.95. Both files were taken with and overscan of 200 but the averages and rms values only...
Bias_075 has a low average of 914.10 and an rms of 28.94
I also forgot to mention that the standard deviation of each image is nearly identical to the others, i.e. the DC offset is the problem (not the...
[ATTACH][ATTACH][ATTACH] Should I remove the overscan to take images? I have 1000 with overscan of 200.
I forgot to mention that I did a setUSBoffset to no effect and the auto bias feature was off.
My STF-8300 has always had about 8 out 1000 bias frames with anomalous DC offsets (after a previous upgrade cured the 8 out of 1000 frames that...
