Alison Tripp and Nick Howes succesfully observe C/2007 Q3 (Siding spring) on March 27 and April 2 at the FTN (Faulkes Telescope North , Haleakala, Hawaii). After images stacking and futher processing, fragment b is clearly visible with offset about 6.5″ from fragment a. In this case I don’t use deconvolution, because fragment b can be measured without any filters. From previous images, obtained on March 23 and 25, splitted object increased distance from parent body.
