These surcharges are in place to ensure the network remains viable and that all members pay their fair share.
- Minimum of 15 minutes of billing time per telescope, it is advised that your total exposure time is greater than 15 minutes to avoid this surcharge.
- Exposure under 120 seconds will trigger session billing.
- Some telescope directives will trigger session billing. This is to ensure that we cover the overheads, some functions place extra demands on the telescope and greatly reduce its image acquisition ability.
Any functions that trigger session billing will be displayed in red before you start a plan. Other directives like #waituntil and #chain will trigger session billing.
- Subscribed members have the choice between session billing or exposure billing. View session vs exposure-based rates here: https://www.itelescope.net/session-vs-exposure-pricing
