How to read A/B codes

Quick start (3 steps)

  1. Set target Right Ascension and Declination (RA/Dec) and chart parameters such as Field of View (FOV), Position Angle (PA), mirror, and magnitude limit.
  2. Import an Imaging planner (A9) or Mosaic Planner Pro (A12) share URL to apply camera or mosaic overlays.
  3. Export the same chart as SVG, PNG, PDF, JSON manifest, or stars CSV.

How to use Finder Chart Pro effectively

Use this page when the final deliverable is a chart you can take outside, print, or share with another observer. It is the right next step after you already know the target coordinates and want orientation markers, scale context, and optional overlays instead of another timing score.

Best workflow

  1. Resolve the target first if the name or catalog ID is still ambiguous.
  2. Set chart scale, orientation, and mirror/rotation options to match the telescope or camera view you actually use.
  3. Add overlays only after the base chart is readable, then export SVG, PNG, PDF, or JSON for the field workflow you prefer.

FAQ

What should I enter first?

Start with the target coordinates and one practical chart scale. Once the chart is recognizable, adjust orientation, mirror, and overlay settings to match the eyepiece or camera view.

When should I use this instead of Mosaic Planner Pro?

Use Finder Chart Pro when you need one readable chart around the target. Use Mosaic Planner Pro when your main problem is panel centers, overlap, and the geometry of a multi-frame imaging grid.

Can I share the same chart setup?

Yes. The shareable URL keeps the chart inputs so another observer can reopen the same field scale, orientation, and overlay choices.

Does this page upload coordinates or images?

No. Core chart rendering runs in your browser. Exports are generated locally unless you explicitly share the URL.
