pandoraefretum Posted May 29, 2019 Share Posted May 29, 2019 Hello! I would like to share an exciting target A couple of nights ago after splitting the Double-Double, I decided to observe Epsilon A Bootis ; called Izar, or Pulcherrima This is one notch harder to split, because Orange K type mag 2+ Izar easily drowns out its companion blue Epsilon B (mag 5.something) With my Nexstar 6se and 10mm no show for Epsilon B ; however with 6mm it did show up !! A fine, fine sight... even if some excellent optics are needed to split it. Colour contrast striking, and on the whole a super worthwhile target / exercise... perhaps a well known one, but was new for me!! Ciao, and somebody please shoo away the clouds!

DirkSteele Posted May 29, 2019 Share Posted May 29, 2019 Pulcherrima translates more or less as "most beautiful" and is reportedly what Struve said when he split Izar for the first time. Definitely an appropriate turn of phrase for a wonderful double star. Link to comment Share on other sites More sharing options...
John Posted May 29, 2019 Share Posted May 29, 2019 Nice report Izar is indeed a fine binary star - I was observing it myself last night, during a gap in the cloud cover. Alkalurops (Mu Bootis) is another fine binary in that constellation - a bright star with a tight dimmer pair very nearby. Delta Cygni is also starting to show well later in the evening as well now - another nice challenge ! Link to comment Share on other sites More sharing options...
Waddensky Posted May 30, 2019 Share Posted May 30, 2019 Yes, Izar is a lovely double star. Thanks for sharing your observation. Splitting them can be tough and requires a good seeing. Link to comment Share on other sites More sharing options...

Sky Safari shows a number of components... and it's a Variable double... as intriguing as its name suggests! On my list, thx, John Link to comment Share on other sites More sharing options...

Ben the Ignorant Posted June 4, 2019 Share Posted June 4, 2019 Izar is famous for being pretty and being a good test of the telescope, the observer and the sky conditions. It has been split by oldtimers with apertures around 2 inches only but even my 5-inch Celestron has a tough time with it when the air is not super steady. My 80mm does not require such rare air conditions, though. Link to comment Share on other sites More sharing options...
