This would be extremely helpful for planning imaging / observing sessions. A new tab labelled" Calendar" should be created and upon selecting it the following would be great to have:
1. A monthly calendar showing all days in a month
2a. Each day should show Twilight Start and End, Astronomical Darkness Start and End, Sun Rise/Set, Moon Rise/Set on iPad
2b. Below this calendar, upon clicking on each day it should show Twilight Start and End, Astronomical Darkness Start and End, Sun Rise/Set, Moon Rise/Set on iPhone
3. Each day should show the lunar phase
It would be nice to be able to check when an observing or imaging window exists and what would be the ideal time for one to show up at an observing site to get started!
