You can naturally work ahead and those using GO TO mounts will probably want to do so. 2 Start when it first gets dark at your location. The actual starting time (as well as all the other times indicated) will vary depending on your latitude and location in the time zone. WORK QUICKLY TO OBSERVE THIS FIRST SET OF OBJECTS BEFORE THEY SET. 3 Sometimes M74 may not be observed with a smaller telescope because it get lost in the glow of dusk. However, it will most likely be visible and located with a larger telescope on a GO TO mount. Page 1 of 5

You ve completed a marathon of the highest order! 7 Often M30 may not be observed because it gets lost or washed out in the glow of sunlight before it gets high enough in the sky to observe. It is possible to see this last object, but to have the best chance, you will need 1) a clear shot of the eastern horizon, 2) the exact time and direction of its rise as determined from a planetarium program like Starry Night and 3) a larger telescope, at least 8 inches in diameter (10 inches or larger even better) on a GO TO mount because you will not be able to find it manually. Additionally, because this object will be so low in the sky, and competing with a sky lightening, you will most likely capture only a fleeting glimpse of it. Page 5 of 5
