Observatory members pay modestly higher dues to help support the observatories physical plant. In exchange, they have personal access to the observatory buildings and club instruments, in addition to the clubhouse and grounds. Observatory membership is for those who want to use the clubs instruments in their own observing programs, want the option of storing equipment on site (subject to additional fees and on a space available basis) or just want to do a bit more to support the Observatory. Cost is $50 per year.

For those who are willing and able to support the club with a $50 donation on top of their observatory level membership. This is a $100 payment of which $50 is tax-deductible. Sustaining Membership
