DSLR Astrophotography 101: Exposure Settings | OPT
- https://optcorp.com/blogs/astrophotography-101/exposure
- We are assuming you’ve already got a DSLR and a lens or two since progressing in any course requires the proper materials. We’re sure that camera has manual controls to adjust the aperture, shutter speeds, and ISO, and that you know how to use these settings to some degree. If you’re still a little shaky on these concepts then don’t fret…

- For slow systems under dark skies, it can be as long as 10-20min. Add in narrowband filters (with which DSLRs are quite inefficient), and the "optimal" time will probably be 10-60min, which may be very impractical, and you should use shorter, 5-10min exposures and live with the small SNR loss.

- There isn't going be any significant difference in the temperature of the sensor whether you take 1 minute or 2 minute exposures. The DSLR sensor will be at 10°C above ambient. Some DSLRs are better than others i.e. 6D or 7D MarkII has much lower noise than a T5i. But a cooled camera will have 1/10 the noise of a DSLR under any conditions.

- Exposure times Here is a simple rule of thumb that you can use: A magnitude 0 star will (very very roughly) give you 1 million photons per second per square cm of aperture in the green channel. A 4 inch (diameter) optic has a ~ 5cm^2 * pi ~ 80 square cm aperture , so you get ca 80 million photons per second from a magnitude 0 star.
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.

- With this kind of lens, the exposure time will be about 21 seconds according to the 500 rule (500/24). The sky will move about 0.09 degrees during these 21 seconds (0.0042*21). 0.1 degrees = 7.3 pixels with this kind of a camera (81.4*0.1).

- Shorter exposures may therefore be called for. IN this case, expose only as long as you can go without showing trailing. Use a rule of 200 if you do not have a tracking mount. Divide the focal length of the lens into 200 to find out how many seconds you can go before trailing becomes obvious.
