New guiding record with GigE camera

New guiding record with GigE camera

average of 1460 guiding frames (2h total exposure time)

Better guiding due to an updated modelling algorithm


The picture to the left shows an average of 1460 individual guiding frames obtained at a two-hour exposure on a 12.5mag (V) star. Higher-performing algorithms on modelling the spilled-over light on the pinhole entrance allows now for lower S/N on individual guider frames, thus increasing the guider frequency, which, in turn, leads to a more smooth tracking of the telescope. From modelling the light loss on this average image, a final displacement of the stellar image of only 0.37 arcseconds with respect to the pinhole could be deduced.  The total light loss is below 20%.
