Looking for Bright Stars for Celestron Nexstar 6SE Alignment

Brightest star in the Northern Hemisphere - Sirius

Looking for Bright Stars

for Celestron Nexstar 6SE Alignment
As a reminder, the following Messier lists are available on pages of Astroimaging. If you get a clear night, seven stars may become visible in and around the Orion Nebula, enough for Celestron's Two star Alignment. Run an experiment to see what happens.

Why are we looking for bright stars? Urban astronomy typically has severe light pollution. The largest cities also deal with air pollution and particulate matter suspension. This is conducive to the forming of upper atmospheric haze. Two nights ago, Venus was bright and visible. However, dimmer Mars and Saturn were not obvious and almost not visible. Blame it on several factors, air pollution, light pollution, haze, and planets that are far from opposition. This applies to large cities with populations of 3 million or more.
