How much disk space do you need?

Estimate the total storage for a complete imaging session — lights, darks, flats, and bias frames.

Inputs

Camera Preset

Horizontal Pixels

Vertical Pixels

Bit Depth

Light Frames

Dark Frames

Flat Frames

Bias Frames

File Overhead Multiplier FITS header overhead, typically 1.1×

Results

Adjust the inputs to see results.

Frame size = H × V × (bits/8) × overhead. Total = frame size × total frame count.

All formulas verified by automated tests.
