yep, you'll need to get it close using coarse focusing first, then go to the fine focuser for critical focus... Something bright like the moon/jupiter of venus is good to get you close, as even a fair way out of focus, these bright objects will show up as a really really big doughnut...
Just keep turning the coarse focus knob watching the display.. It will come to focus at F/10. Your field of view will be VERY narrow though... Very very narrow
