I need to find a mount for this telescope but I'm having a bit of troublethe site where i can buy the telescope says.Telescope Tube Attachment Hardware:quot;The Sky-Watcher APO optical tubes come with attachment hardware that allows them to be securely fastened to the SW EQ5P mountThe quick-release tube rings provided with SW ED-APO models 80ED, 100ED and 120ED are cast-aluminum, painted white.quot;Is the SW EQ5P mount the only mount it connects to? or can i get a cheaper mount that will still do the job?
