Here's some practical advice. During daylight hours enlist a friend to hold a confectioner's powdered sugar coated doughnut against a cooperating neighbor's exterior house wall which you painted flat black. This kindly neighbor should live between 300 and 400 feet from your scope and that newly painted black wall should be clearly in sight. Now, with your daylight adapted eyes, center that doughnut in your telescope's finder device and peer through the eyepiece of your telescope. Look at the doughnut. Study it carefully. Take an afocal photo or two of it if you are so moved. Eat the doughnut. Then, when night falls, direct the telescope to the area between Beta Lyrae and Gamma Lyrae and slowly sweep the region until you see something that looks familiar. Voila!! Messier 57.
