Hello, I am new to using a telescope but am an avid manual reader and usually a fairly quick study. I have bought a pre-loved Celestron Nexstar Evolution 9.25 {originally purchased in Sydney Australia in 2014} and am struggling to do the 2 star alignment. I have reset the scope to Factory Settings and have added my location, correct time, STD or DLS time; time zone etc. I take the scope out and level it, align the marks on the base of the motor and on the arm that holds the scope. I point the scope whilst still levelled and marks aligned North. I try to align to Sirius and the scope points to my feet. I have tried following the steps but nothing is working. I have tried using the SkyPortal App and that is more of a success but still not quite. I try to align Sirius and it will point up and very close to the star but not aligning with it. I ask it to GoTo the stars in Orion’s Belt and it will be close but not quite so not aligned....at least it isn’t pointing to my feet. Any suggestions would be welcomed. Thank you.
