In addition to your 8” or 10” Bintel Dob telescope you will need to collimate ( align ) the optics or mirrors from time to time depending on how much the scope is moved around or bumped etc...
Attached are two accessories I have used over the past couple of years that do the task really well
Orion Cheshire eye piece
Orion laser collimating tool
Both available from Bintel
Cheers
