Hoe heeft hij dat ooit ontdekt uberhaupt.. Ben benieuwd!
Hoe de ontdekking ging staat beschreven in deze PDF: “Astronomy&Astrophysicsmanuscript no. aa October 12, 2018“. Zie o.a.:”Donatiello I (Do I) was first found on 23 September 2016 in a visual inspection of a deep amateur image of the Andromedagalaxy region obtained from the composition of a set of images taken during several years with a refractor ED127mm (with an aperture of 12.7-cm at focal ratiof/9) by the amateur astronomer Giuseppe Donatiello ”
“An alternative searching method is the detection of unresolved (or partially resolved) stellar systems as diffuse lightstructures in low-resolution, deep images taken with small telescopes”
