It works!Īll this showed we don't need to fiddle with anything. I explained however that if one knows their Greek alphabet, they can click on the lower case sigma (σ) in the Stellarium search window and follow it with the numbers. It is curious that Stellarium does not recognise "STF 855" or "Struve 855" while searching! That's disappointing to me, especially when it pings SIMBAD. Sadly, I relayed, many software programs don't recognise Greek characters in search tools! That's why I show "Struve" (the discoverer name) and "STF" (the WDS discoverer code) as alternates. ![]() That's the official double star designation according to the Washington Double Star (WDS) database. I show the double above with the common symbol, the upper case Greek letter Sigma: Σ855. I pointed out things are a little tricky with Greek letters. And, in fact, Stellarium will show the alternate designations including the Struve number, the SAO code, and the HIP number. If one searches for "HR 2174" (without the quotes), we will land at the correct double star system near Betelgeuse. I used the example HR 2174 Orionis also known as Σ855 (Struve, STF), SAO 113507, and HIP 29151. And let's simply use the "standard" way, the Object tab, in the Search window. F3 or Ctrl-F or the magnifying glass button in the left toolbar. Step one is to get into the Search window in Stellarium. ![]() I shared that I thought searching for doubles in Stellarium is straight-forward. ![]() In other words, which catalog or catalogs and what level of objects need to be downloaded into Stellarium to find them. Reacting to my double stars bulletin in the RASC Toronto Centre forums, he said he was going to start trying double star observing, particularly given his bright urban skies.Ĭan you give me a tip as to what search in Stellarium is best used to find the objects. Had a very interesting conversation with John D today.
