Description

Here is another path you can take in your amateur astronomy journey, variable star observations. This is a view of the star R Andromeda (R And) taken on 14 Nov 22 and 14 Dec 22 showing the change in brightness over that 30-day period. This star will change in brightness from magnitude 5.8 down to 14.9 and back again over a period of 409 days. You can read more about these types of variable stars at (https://en.wikipedia.org/wiki/Mira_variable). While you need specific filter sets to submit your variable star data measurements to variable star organizations, my observations, for the moment, are for my own knowledge bank.
