The cost of your Advanced Requests will be charged in credits and depends on the total exposure time of your images, the observation overheads, and on which telescope you're using (see Telescope price list).
The unit cost per credit is $ 1.00, € 1.10, £ 1.00, A$ 1.60 and C$ 1.30, the currency will depend on your country of residency.
You can buy credits directly from the Telescope Live app, using your credit card.
Telescope prices range from 35 to 200 credits per hour of observing time, depending on telescope model and moon phase. (See the full telescope pricing list)
You will need to buy credits because you are basically renting our telescope for observing a target of your exclusive interest.
The credits are necessary in order to pay all the expenses behind running a professional and top-quality telescope.
Credits can only be bought and used if you are on a Silver or Gold plans, as only these plans give you access to Advanced Requests.
Credits don't expire! If you suspend your subscription, or downgrade for some time to Bronze, you will always be able to re-subscribe to Silver and Gold to use your leftover credits. Note, however, that we do reserve the right to delete your account, together with your credit balance, if you don't use your account to submit Advanced Request for at least one year.
