Can anyone identify my mount? I bought it second hand. There are not markings on the mount, it only says EQ mount. I know this motor is attached: http://www.teleskop-express.de/shop/product_info.php/info/p8378_Bresser-Messier-RA-Motor---Controller--MON1-and-EXOS-1.html

So I am inclined to say I have a MON1 or EXOS1 mount. Googling this comes up with this video: https://www.youtube.com/watch?v=1LD6zwkdsZw it looks exactly like this. I went to the store and bought a telescope that should fit: sky watcher 150/750 http://www.astroshop.de/skywatcher-teleskop-n-150-750-explorer-bd-ota/p,15564

Now apparantly my mount should be an EQ3-2, which is also what seems to work with the telescope I have. However I cant balance the telescope as its too heavy. Now either a counterweight is missing, or the telescope is too heavy. I think the telescope is 5KG but I cant find a source on this as there are so many variaties of the same telescope goign around.

Googling my mount says it could take up to 7kg, but that its recommended to stay below this. But 5kg telescope + 5kg counterweight is too much right?

Tl;dr Should I buy extra counterweight or new mount?
