A 'point' is iTelescope currency. Your membership plan comes with a set number of points, When you join to a new plan or when your membership plan renews you accumulate 'points' in your account, and you can even buy additional points if you are running low.
Each telescope has an hourly imaging rate expressed in 'points per imaging hour', this is the cost of using one hour of exposure time on that given telescope. Each telescope has it own hourly rate, which is influenced by your membership plan and the illumination of the moon. Typically the higher the membership plan the lower the hourly imaging rate per telescope. You can find the telescope rates here and on the launchpad.
You exchange your accumulated points for imaging time on a telescope.
Example: If the telescope rate is 50 points per imaging hour and you have 100 points in your account, this means that you have 2 hours of imaging time on that given telescope.
You only pay for the imaging time you use, if you take a 5 minutes exposure you only pay for 5 minutes of imaging time in points, each time you use a telescope you consume your points along the way, simple!
