6: Polar Align

Now at end of the summer it has come darker again at the nights and I can do outdoor test again. But I have to solve one problem, normally I always do the polar align with the drift align method with help of the auto guider. With this mount which doesn't have a auto guider I must do it an another way, the mount has a built in polar finder scope with a reticle screen. I just have to know where to put the polar star, it will change with time and place, I need the hour angle.

I found these two very handy apps to my Android telephone that can give me that information:

• https://apkpure.com/ polarisview/com.watware.www.polarisview
  PolarisView
• https://apkpure.com/ simple-astronomy-tools/com.hrastro.simpleastrotools
  Simple Astronomy Tools

The second one also have some other tools. I will write later how successful this was when I have tried it out with my 150mm lens.
