When doing astrophotography you usually need to get at least certain amount of light subs to stack and get a reasonable overall signal-to-noise ratio.
With Telescopius you can see a list of Deep Sky Objects which will be high in the sky enough time for you to get enough subs. To do this:
-
Go to the DSO Search page
-
Enter your astrophotography session time limits. In this example, we’ll use the astronomical sunrise/sunset and seize the whole night.
- Now set the minimum altitude you’d like the targets to be when imaging, and for how long. Let’s say you’d like to image targets when they are at least 40 degrees above the horizon and take at least 60 5-min subs, this means roughly 300 minutes or 5 hours. So the minimum altitude inputs would look like this:
These settings will end up showing you objects which stay at least 5 hours above 40 degrees between the astronomical sunset and sunrise.
You can also play with the search parameters to filter objects transiting North/South, or East/West.
