Here's a clear text summary to match your query:

FOV (degrees) = (sensor width in mm / telescope focal length in mm) × 57.3

One of the most common disappointments in astronomy isn’t bad weather—it’s looking through the eyepiece and realizing the object doesn’t fit. You expected the Andromeda Galaxy to fill the frame, but instead, you only see its bright core. astro+fov+calculator+hot

If you want to do it by hand, the standard formula is:

You can calculate FOV manually using these standard formulas: Standard Formula (Degrees): Sensor Size Focal Length Here's a clear text summary to match your

The Astro FOV Calculator Hot offers a range of benefits for astronomers, including:

def hot_fov(temp_celsius, focal_length_mm, sensor_width_mm): # Thermal expansion coefficient for aluminum (23e-6) thermal_expansion = 1 + (23e-6 * (temp_celsius - 20)) adjusted_focal = focal_length_mm * thermal_expansion tfov_rad = (sensor_width_mm / adjusted_focal) tfov_deg = tfov_rad * (180 / 3.14159) return tfov_deg At 1.63 arcseconds per pixel

, he checked his pixel scale. At 1.63 arcseconds per pixel, he was right in the "sweet spot" for his local seeing conditions—not too sampled, not too square. The plan was set: : The North America Nebula (NGC 7000). : 80mm scope + 0.8x Reducer.
