Focus positions for QHY10 with TS OAG/Flip mirror on Sky Watcher DS Pro 72mm OTA

Note use of 35mm extension tube between scope and TS OAG/Flip mirror – however in this configuration eyepiece will not achieve focus although camera will. Need to replace 35mm extension tube with shorter T-adapter which will push camera out further from TS OAG/FM and allow eyepiece to also focus.
