Especially for Orions trapezium and some other targets 10sec blows out the image so a shorter exposure capability would be useful
You can easily do only 3-4 shots and developer those for the trapezium. Then you can use a photo tool to Copy paste this zone to the originale image (the one with more integration)
Good idea still would like variable exposure times
We are developing a function with shorter exposure time and believe it will be available online soon.
