    Welcome to the forum!

    And don't worry about your English, I guarantee your English is better than my Korean!

    I recently got my SkyTracker but I've not yet had a chance to use it so I'm not going to be a great help to you at this time.

    But you might find this thread a little helpful: Wide field with the iOptron SkyTracker CamelHat did a very nice 25 minute exposure at 55mm. I think that is quite impressive.

    If you are doing your imaging at 200mm you will not be able to track as long as you will at 70mm.

    If your polar alignment is very good you will be able to track longer than if your polar alignment is poor.

    You will probably find that you can track longer when you are pointing at something near a celestial pole than if you are trying to image something at the celestial equator.

    The only way to tell what works for you is to try it out.

    I'm sorry I cannot help you with the balancing. Hopefully someone who can help you with balancing will see your post.

    I use a 210 zoom on mine and it is very important to lign it up as perfect as you can. I hope you have the ball joint mount atachment for your tracker and the knobs are all tight, it can be a pain to lign up but all must be tight and will work fine. Check the alignment regularly if you can, I remove the alignment scope so the camera does not bump into it.
