Hi Peter, mate there is a website that allows you to search for objects that are visible from any location by entering your long & lat and setting some search criteria. It even tells you the best time of year to observe each. I have set the location to Portland as an example and done a search for Messier objects. the link below will take you to the results of that search. Once you get there you can change your location or your search criteria by clicking on the button at the top that says "click here to adjust filters". If you click on the details link to the right of each object it will show you a photo, some are good quality some are not, and tell you all sorts of information about that object including when the best time to observe from the currently set location. Hope this helps. I use this website a lot and find it very good. Have fun.
