Hi here's my observation from 3/24/2017 : Ngc 5139 globular cluster in Centaurus ; aka Omega Centauri ; magnitude: 3.68 ; size: 45' x 37' ; the largest and brightest of all globular clusters ; this object is amazing even though it only transits my observing sky at 14 degrees, it has two dark areas at the bottom known as the footprint. I used a 21mm Ethos at 115x with my 14.5 StarStructure f/4.3
