- Choosing an astronomy camera for your telescopeCompare sensor geometry, pixel scale, optical coverage, cooling, and workflow in that order—before price or megapixel count decides for you.01 · Planning guide
- How to check telescope and camera compatibilityA five-gate compatibility check for framing, sampling, corrected field, back focus, and the complete mechanical and mount load.02 · Planning guide
- Astrophotography mount payload planningHow to estimate a realistic imaging load before your mount starts struggling.03 · Planning guide
- Focal reducer compatibility: what to check firstA reducer can widen the field and shorten exposures, but only when the rest of the system agrees.04 · Planning guide
- Matching a guide scope and guide cameraA useful guide setup is about scale, focus, rigidity, and reliable software—not just magnification.05 · Planning guide
- Spacer and back-focus planning for an imaging trainMeasure from the correct reference plane, add each occupied distance once, and separate a numerical match from a mechanically compatible imaging train.06 · Planning guide
- Planning telescope field of view before an imaging sessionCalculate the real camera rectangle, reserve edge margin, and turn the result into a framing, rotation, or mosaic decision before the session.07 · Planning guide
- Why pixel scale matters before you buy equipmentPixel scale helps you avoid buying a camera and telescope combination the atmosphere cannot support.08 · Planning guide
- Planning a deep-sky mosaicA mosaic becomes much easier when you plan panel count, overlap, and edge space before the first night.09 · Planning guide
- Choosing an exposure length without star trailingA calculator can suggest a starting exposure, but your mount, sky, and guiding still get the final say.10 · Planning guide
