Hence I couldn’t use my 250mm central pier with a Sidereal Trading Steel pier adapter ( my pier is still sitting under the deck unused )
Just some advice from a reputable company and Astrophotographer

Hi Martin...250 mm OD and ID 225 mm expect.thats beefy..yum.
Did you put reo in before you added concrete?
My idea is to drive star pickets into the soil past my pad but in effect continue the line of pickets from soil to top inside the pier... I will probably wire them together ..if you have two seperated by say 4 inches ( I will do it with four) and wire them it becomes very strong ..I cant give enginering figures but you create a beam effect..
Anyways I will do my best if it is not satisfactory I will just build another observatory...that will be my sixth..but next time I will get a dome now that I have this remote stuff working for me...
