If you would like to find Uranus, this is a good opportunity as Mars and Uranus will be within 1 degree from Feb 11 to the 13th. Best time would be before 9 pm so they are high enough in the sky.
Looking at my notes, I had to get it over 100X before it didn't look like a star. At 266X it was a small blue ball in my 8" Dob. But I would expect you could see the blue ball in a 70 mm telescope if conditions will let you get it over 100X.
Happy planet hunting! Love to hear success stories.
If you need help, ask.
