- For widely varying focal lengths where you want to record a similar light density, include thepixel angular area. This is CEFA: Clark Exposure Factor Angular area, CEFA = aperture area in square centimeters * exposure times in minutestimes angular area in arc-seconds. CEFA = (pi/4) * (aperture diameter in cm)2* time in min…

- The formula is500 divided by focal length ≈ longest exposure time in seconds w/o streaking stars (500/ (focal length) ≈ exp. in seconds). This is called the500 Rule. The problem is modern camera sensors out-resolve film quality, with sensor pixels now …
Film versus Digital for Astrophotography

- The total exposure for the film image was 80 minutes in three individual exposures of 15, 20 and 45 minutes. The total exposure for the DSLR digital image was 80 minutes in 40 individual exposures of 2 minutes each. Both images were made with an IDAS LPS filter and both have the same amount of total exposure.
ISO and Astrophotography | The Best Settings for a Clean Shot

- Unlike daytime photography, astrophotography requires multiple images (sub-exposures) taken using the same settings, which are then stacked on top of each other using dedicated software. It is common to see very little detail in a single exposure, and in some cases even in your stacked image with your sub-exposures.
Astrophotography on film. — Jason De Freitas | Jase.Film
- https://www.jasondefreitas.com/tutorials/astrophotography-on-film
- Let’s start with a digital exposure as a reference point so that we can understand what the challenges of film are. A typical digital Milky Way exposure: f/2.8, 25 seconds at ISO 3200 . The main challenge with analog astrophotography is reciprocity failure. Film doesn’t maintain a linear response for exposures longer than a couple of seconds — doubling the …
Long Exposure Vs Image Stacking For Astrophotography

- Together, these settings form the Exposure Triangle and work together to define the exposure for the scene. The exposure triangle, linking together aperture, shutter speed, and ISO. If you are stuck in a dark environment and your shutter speed is too slow, t o use a faster shutter speed you must compensate for the loss of exposure (light) by using a wider aperture …
