While there are still equatorial mounts on the market that have motors available for both axes (a minimum requirement for astrophotography), computerized mounts are more plentiful than ever and can be an economical choice since you won't have to worry about adding motorization to your manual mount later on. They are also not as good as other telescopes like SCTs for planetary imaging due to their lower contrast as explained above, but you can still absolutely use one for capturing the planets just at reduced contrast." The biggest support problem common observatories are the lack of possibility of returning the defective dome or walls hence the cost of shipping back can be more than the cost of the observatory itself and meanwhile you don't have any protection for your telescope and expensive gears.
