What is the best way to star hop to a deep-sky object?
Plan your route
Pick a starting point that you can see with your naked eye, like a bright star or a familiar constellation. Use a star chart or planetarium app (such as Stellarium or SkySafari) to identify a chain of stars leading to your target. The route should have 3–5 steps, each involving a star pattern you can recognize.
Before you go outside, study the chart and memorize the shapes. It helps to draw the path or write down the steps. Know the field of view of your finder scope or eyepiece so you know how far each step should be.
- Choose a bright star as your anchor.
- Use a chart or app to plan a zigzag path.
- Learn the field of view of your finder.
- Practice the route indoors first.
Hop step by step
Start with your finder scope or a low-power eyepiece. Center the anchor star, then move the telescope in the direction of the next star in your plan. Use a red flashlight to check your chart without ruining your night vision.
At each step, match the star patterns you see in the eyepiece to the chart. If you get lost, go back to the last confirmed star. Once you are close, switch to a higher power eyepiece to see the object. Many deep-sky objects look like faint smudges, so use averted vision (look slightly to the side) to see them better.
- Center the anchor star first.
- Move in small increments, checking the chart.
- Use a red light to preserve night vision.
- Switch to higher power when you are close.
Common mistakes
- Trying to star hop with a high-power eyepiece, which makes it hard to see enough stars for navigation.
- Not matching the orientation of the chart to what you see in the eyepiece, which can be flipped or rotated.
- Giving up too soon; some objects are faint and require dark skies and averted vision.
