My Astro Window

The horizon doesn’t always meet the ground. Trees, buildings, and ridgelines can block a target long after it rises. MyAstroWindow helps you explore 200 free, hand-picked deep-sky targets, discover when they clear your local obstructions, and see how they fit your equipment’s field of view. FIND YOUR NEXT TARGET Explore the full catalogue of 200 deep-sky targets for free, each paired with real astrophotography images. Browse galaxies, nebulae, star clusters and other celestial objects, and learn about their size, distance, constellation and capture characteristics. Best Targets ranks objects for your selected location, equipment and date. Check when each target is visible, its peak altitude and the effect of moonlight, then choose a target that suits your session. PLAN AROUND YOUR HORIZON Create a personalised horizon map for your observing location. Use your device’s camera to photograph and trace your local skyline, including obstructions such as trees, buildings and ridgelines. Alternatively, create your horizon manually. For photographic horizons, optionally refine the direction of your horizon map using a known bearing to improve alignment. See when an object clears your local horizon, how long it remains visible and when it reaches its highest point. Use the calendar to explore target visibility on future dates and plan nights ahead. CHECK THE FORECAST See how the weather affects your imaging opportunities. Review a five-day weather forecast covering cloud cover, rain chance, wind and dew-point margin, with forecast conditions integrated directly into the target visibility chart. See when a target is above your local horizon and whether the weather looks favourable during that window. Weather forecasts include a free seven-day trial, with optional Weather Passes available afterwards. No recurring subscription is required. FRAME WITH YOUR EQUIPMENT Set up your telescope, camera and other equipment to see the field of view and how a target fits in the frame. Pro lets you save multiple rigs and compare framing across up to three setups. TRACK YOUR IMAGING PROJECTS Create a project for each target, set an integration goal, record progress and keep notes. Add capture details, log actual integration time and revisit completed sessions in your logbook and calendar.
