No, buddy. Observatory quest is not required if you have not already started it before talking to professor in a house, north of observatory. :wink: ---- Information on how to get those tools: I, myself, have read the Tip.it's Treasure Trail guide, and I can assure that it explains very well on the Navigation tools that you're looking for. Oh well, if not, I can help you as well. How to start You need to have a Coordinate clue scroll in your inventory, try to EXAMINE it before as well. Now, head to professor located in a house, NORTH from observatory. Talk to him for the Treasure Trails location. How to get a Watch Go to Clocktower (a house located south of Ardougne Zoo with a quest sign). There, talk to Brother Kojo, and he will give you a watch. How to get a sextant Now, head to the Port Khazard docks. There, talk to Murphy, and ask for a Sextant. Now, you should have a sextant, and a Watch. How to get a chart After having a sextant, and a Watch in your inventory, head back to professor. Now, he should give you a chart. --- So, now you should have Sextant, watch, and chart in your inventory. Hope, I have not *spoiled this with this complete walkthrough*. My intentions were to just help you. But, again, if you would have read the Treasure Trails guide carefully then you woulnd't have had these problems. Oh well. Good Luck. :D
