SW 200P Dob question

[DRT]

Can someone with a SW 200P Dob with the standard Crayford focuser please tell me what the height of the focuser is from the base where it joins the OTA to the top of the 2" extension tube? Please tell me the distances for fully retracted and racked all the way out.

Thanks

Retracted mines 12cm (4.75")

Racked out it's 15.5cm (6 1/8th")

(Just realised - mines not the dob you asked for but the regular ota - there may be a difference)

not sure if it helps (dont have the stock focuser on my 200p skyliner) but the focal plane on mine is approx 143mm above the tube.

Thanks guys
