Thx for your time. It takes effort to right down what you have observed . Often reducing the time at the eye piece to jot down what you have "bagged" for memory triggers, that's the way I have done it . Some use a dicta-phone but generally they self illuminate .A phone can work for voice recording too.
NGC 5139 The grand Omega Cent is always a show stopper. Tell me if I am incorrect but i have been told what you see is the Owls Eyes with this wonder. A twin region of dimmer stars... Here is my last AP attempt. Cheers
