Hi Carole , thanks for the answer 👍 that is the tracker I bought and received last week  🙂 cloudy as it is there was no chance to practice ! The weight is the limit with the tracker because I wanted to take pictures with the Nikon d500 with the sigma150-600 but thats a way to heavy as they say ! So with the 80-200 it must me possible so on the cropcamera I have 300 mm and even another 1,4 Crop for 375 mm . 

Hi there and welcome to the forum!

I have successfully used an Omegon MiniTrack LX2 (which is a mechanical type of tracker) with a Nikon D7000 and a 70-300mm zoom lens. My kit was at the limit of the tracker capabilities but I managed good 2-3 min exposures at 70mm and 30-90sec at 300mm. It will really depend on the focal length, exposure and how the camera sits with respect to the tracker. Remember the "100" or "300" rule, which is well explained in these two guides by Christian Fattinanzi:

Have fun with this hobby!
