I have used one for some imaging......I like it as a rich field scope for visuals {its primary purpose
} although even moderate stars exhibit strong colour fringing, when you hook up a DSLR this is enhanced further. I don't know how effective filters/field flatteners would be with the scope but one of the moderately priced ED scopes are a better option. The OTA weighs roughly 5-6kg.
