Finished my dark and bias master yesterday, then set about fixing the damned column defect (a LONG one). Now that's done, getting NICE calibration, now only needing me to finish the lightbox (using strip white LED's and milk-plastic acrylic sheet from a sign maker) to do the flats.
I ended up with 5 hours worth of darks, and 200 bias frames (maybe overkill
). Will do another run of darks tonight, and then recombine into a master AGAIN (and remove the column no doubt AGAIN! - one day I will get a Class 1 sensor
)
The resulting overall effect seemed worth it to me -so much so I reprocessed ALL my paltry IC2944 data again:
