Hello I wondering if any one can help me please , I recently brought a skywatcher discovery 150p and using a gps mouse , I've done all the alignments correctly with the 2 stars . The problem im having is I can't see the galaxies ,the telescope goes to the correct position and ive scanned the area moving the mount and used both eyepiece 10mm and 23mm but nothing . Any advice or tips would be welcome please
