PIER-02 Pier 12 Defect Map

Hello everyone,

While Pier 2 is down and being repaired I thought it might make things a little easier for those of you struggling with the unreliable columns on P12 to create a defect map for the sensor.

Its not uncommon for CCDs to have these sorts of defects however dealing with them can sometimes be a little tricky.

I will make the the Pixinsight Instance available to download. Simply run it after calibration and before stacking. For those using Batch Pre-processing you will need to point the cosmetic correction tab to the instance for it to correct the defects. You can in addition alter the cosmetic correct to take care of any hot or cold pixels by activating the detection tick boxes and using the sliders.

Here is an example of an uncalibrated frame from Pier12 showing the artefacts against the repaired and stacked result.  

Hope this helps

regards

Peter Shah
