16 Determine in which constellation the object lies. Now , find the constellation in the sky . If you do not recognize the constella- tions on sight, consult a planisphere. The planisphere gives an all-sky view and shows which constellations are visible on a given night at a giv en time.
17 T ur n the motor drive on. Adjust the telescope’ s focuser so that the image appears shar p in the camera’ s viewfinder . The camera’ s shutter is now ready to be opened. A remote shut - ter release must be used or the image will be blurred beyond recognition.
