- 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 minutes * angul…
Astrophotography: How Long Can You Go? - Sky

- You can use the "rule of 500" to determine how long your camera can expose before stars begin trailing. But in reality, how long you can expose depends on your focal length, pixel size, and where you are pointing in the sky. Richard S. Wright Jr. Rule of 500 (or 300) If you've never heard of the Rule of 500, it's quite simple.

Exposure Times — Starizona

- The exposure time was 20 minutes. If your telescope has a focal ratio of f/10, you need an exposure of 40 minutes to get the same results, because f/10 is half as fast as f/7. However, the other factors do come into play. To determine a more accurate exposure time, use the calculator below. Equivalent Exposure Time Calculator Planetary Imaging

- If it takes one hour of signal collection to obtain a good image, you can instead combine 12 individual five-minute exposures. In theory, you can …
More short exposures or fewer long exposures

- 12 subs at 10 second exposures 2 subs at 60 second exposures Obviously these images are very rough looking, as a 2 minute total exposure time using an unmoded DSLR is nowhere enough to get any kind of decent image. Remember you need to make sure you are taking as many subs as you can to get the best results possible.

- Optimum Exposures Calculator. Astrophotography can seem like a fair bit of guess-work. In general the process of capturing images involves doing so at a certain exposure length and multiple times for the same target, using the same filter. The idea here being to combine the images captured during calibration in order to reduce the pronunciation of noise and increase …
Finding the Optimal Sub-frame Exposure - Astrophotography

- From Equation 6 we know that we need to overwhelm the second term by 4.38 to achieve the optimal exposure so that means we should expose for 4.38*20 minutes = 87.6 minutes, longer than the 60 minutes maximum exposure of an SBIG camera.
Formula to Calculate max exposure time. - Cloudy Nights

- 1. Exposure time will depend on many factors. Darkness of the site. Moon on/off. Gain of the camera, etc. Just take a test shot and look at the histogram. You want the histogram peaks to be in the first half of the range. My exposure times with AT72EDII and ASI294 (Gain 200, offset 20) with a LPro filter vary from 60 to 360 sec for a single frame.
Why use exposure time over 30 seconds?: …

- A 1-minute (tracked) exposure is going to have higher (if not much higher) quality than a stack of 10 6-sec exposures, because the latter case involves 10 readouts and therefore 10 units of read noise while the former only one read out. So, getting a tracker to take longer exposures is a logical next step, but you don't have to do it right away.
