Put the eyepiece with the largest number written on it into the focuser. Go outside during the day time and practice focusing on a distant object.

Magnification is the LEAST important property of a telescope. Quality optics and aperture are much more important.

The best bang for the buck is a reflector style telescope ion a Dobsionian mount. You get the most aperture for the least amount of money. Like this one--

The scope above has 6 inches of aperture and is mounted on a very stable alt az mount called a Dobsonian mount.

Here is the info page on the Orion web site:

You can also call Orion Customer Service. Some eyepieces will not come to focus. Try the one with the largest number written on it.

Also your scope could be way out of collimation. Watch this video:

During the day time line-up the small finder scope with the main tube. Use the eyepiece with the largest number written on it. Site on a distant object with the main scope. Then line- up the crosshairs on the finder with out moving the main tube so BOTH are pointed at the same object.

Locate a local Astronomy club and attend their star parties. You have a good beginners telescope by the way.

Learn how to collimate the telescope. Watch this video.

Orion SkyQuest XT6 Classic Dobsonian

Mars is a tiny object at best, needing about 400x to view. We are now fairly well past opposition, so it is even smaller. That power would call for a 3mm eyepiece (6mm with 2x barlow is the equivalent). Try the highest power eyepiece that you have.

Can you please advise if the wireless router should be left switched on or will it reduce the life of the router if I switch off when not in use

Should make no difference, however if you have not activated the security feature on it, anybody with a wireless device can gain access through your system.

Marchwood storm 60 telescope

you use eyepieces to zoom in and out. lower mm eyepieces like a 6mm will have a high magnification. and a high mm eyepiece will have a lower magnification.
