It is much easier to use a finder chart at the scope rather than trying to use a relatively bright computer outside. If you can print a few charts- one with about 90deg width as a naked eye finder and then print a more magnified chart with the object you want to see and hopefully a bright star on the chart that you can identify from your other chart. I tended to make my charts 8deg across and printed them reversed like the image in the eyepiece. This will depend on the type of scope.
You can then star hop when sitting at the scope with the chart and a dim red light.
Charts can be printed from any planetarium software and some are free like CDC.
