sigma Orion - an enigma ?! - (solved in October,29)
My last capture shows Sigma Orion star. Wikpedia says it is a system of five stars. But I saw seven stars, despite of bad focus. Searching in Aladin Sky Map it seems to be 3 stars together Sigma, and 2 stars together D or E, really I don't know which of them. Therefore it should be 7 stars. Searching in Sky-Map I only saw 2 stars in Sigma's region and I saw 2 stars together D or E, too.
My question: Sigma Orion is a 5, 6 or 7 stars system ?
