The option in VSP to show a DSS image in a chart is temporarily not working (Feb 24, 2017). NASA SkyView, the source of the DSS images used by VSP, is having disk issues. It is not known how long they will be down. If you need a chart with a DSS image in the background, please continue to try VSP at intervals - as soon as SkyView is back online, the DSS feature should work.
Thank you for your patience and apologies for the inconvenience.
Good observing,
Elizabeth Waagen, AAVSO HQ
