Calculators

Combine multiple calculators into a single workflow. Assess your rig's suitability for a target under your sky conditions.

Calculate arcseconds per pixel for your camera and telescope combo. Get sampling quality feedback based on your seeing conditions.

Calculate how much sky your sensor captures with your telescope. Compare your FOV against popular deep sky objects.

Determine optimal sub-exposure length based on your sky conditions, filter type, and camera characteristics.

Analyze if your mount and guiding setup can deliver round stars at your imaging scale.

Calculate and verify your backfocus spacing to ensure flat field and round stars across the frame.

Estimate signal-to-noise ratio based on your total integration time and target brightness.

Plan your imaging sessions by checking target altitude and visibility windows for your location.

Calculate the number of panels needed to cover large targets with your current FOV.

Get filter recommendations based on your sky conditions, target type, and camera setup.
