ED127 @f/45 + DIY MaxCam 1280
AstroBin Image Of The Day
Each single source image, all taken with the ED 127mm refractor used at f/45 + ROI, is the result of the manual stack of 15-20 "super-frames" (ie of excellent quality) extracted for inspection and visual evaluation from films composed of 250 (therefore about 7% of the total). The individual subframes were manually aligned on the middle centroid (the large white disk that is seen is not Sirius, but his confusing figure!), And rotated until Sirius B matches the theoretical curve of the orbit, with good agreement. The image is therefore not a stack but a multilevel composition..
