Ideal Exposure Calculator — Starizona
- https://starizona.com/blogs/tutorials/ideal-exposure-calculator
- This calculator allows you to determine the ideal exposure time for subframes that will be stacked. It requires that you take a test exposure using your CCD imaging setup and measure the background sky value. Please refer to the CCD Imaging Theory page on Optimum Exposures for the details behind these calculations.

- To calculate the exposure ratios at zenith input the average height of the star and the 3 ADU values derived from about 30 combined exposures which fully calibrated. Clicking Save This Dataset will save the ratios in a cookie on your local machine for you to use in the Image Colour Balance tab. You will be prompted for an identifying name, make ...
Ideal Exposure Calculator - Experienced Deep Sky Imaging

- Ideal exposure time is calculated: Ideal Exposure=C*R^2/P The sheet also goes and calculate what is the unity gain of your camera (just a useless bit of information). In the example is my ASI1600's information and the calculated unity gain came back as 138... REFUND!
Calculating Correct Exposure for Astrophotography Sub …
- https://www.dpreview.com/forums/thread/4377640
- A common way to set sub-frame exposure in astrophotography is to adjust the exposure so that the back of camera histogram shows the sky peak at the 1/3 to 1/4 level. Another way, which seems more rigorous, is to set the exposure so that the sky background noise “swamps” the sensor read noise. ... The calculator seem would seem to agree with ...
Optimum Subexposure Calculator (and more...) - AstroBin

- One key step is that we need to take a test exposure with the specified equipment, to calculate the Background Flux and use it as a reference to give the Optimum Exposure Time for this conditions. Apart of the Optimum Exposure, I added some other calculations that can be useful to plan the astrophotography sessions needed for a given project ...
