Minor annoyance with az mount

[Corne de Klerk]

Hi Everyone. Newbie to stargazing as well. Was given a Celestron Astromaster 70AZ / 70mm refractor telescope as a gift and tried my first stargazing last night. 
I am based in the southern hemisphere and wanted to view Jupiter which means that it is located high in the sky and thus I had to fully tilt the telescope to point towards the planet. I managed to find Jupiter however when I wanted to show my family, the telescope moved on its own and it took me a couple of minutes to find it again. 
The question is: Is it the AZ mount that is moving even though I tightened the AZ handle and how can I prevent this? Same suggestion as per the previous discussion?

Many thanks!

If you set the telescope mount to look at a fixed point in the sky, the earths rotation means that the object will have moved out of view in a very short time.

Many thanks! Makes completely sense. A lot to learn

Hi @Corne de Klerk and welcome to SGL. 

Just remember that the higher the magnification of the eyepiece, (i.e. lower number), or different eyepiece design used, the faster the object will travel across the field of view, e.g. using a Plossl (50deg} & Nagler (82deg), of the same focal length.

Below is an image of my TeleVue 13mm's...

...shows how much the Nagler design has changed/evolved over the years.

Hi Gaj, welcome to SGL. We all have to start this great hobby somewhere.
