An exposure time calculator for the Blaauw Observatory Gratama Telescope.
Welcome to the documentation! This program is an exposure time calculator for the Gratama Telescope of the Blaauw Observatory. It is meant to aid you in your planning by allowing you to estimate the expected signal to noise ratio, required exposure time or limiting magnitude for your observations. Please not that this is only an optimistic estimate, i.e. quantities like the quantum efficiency are (still) set to 1 and therefore definitely overestimated.
