Now if you had made provision for a bolt to be set in each corner of your concrete base and an angled metal strut bolted to the base and also to a plate at the top of you scaffold pole, it would finish looking like a skeleton pyramid, it would have killed the vibration and it should be very solid. just floating this idea for anyone els wanting to make a light but strong garden mounting, without putting in a big concrete/metal central pillar :)

Steve,

Focusing problems in the BackyardEOS, instead of the Bhatinov, try a more simple version just a Y made from same width strips as your mask, this will give you as much as a 1f stop brighter image and work the same.

Steve, MoonLite focuser's are a dream to use, I would be interested to know which way up you had your scope when you did the change over, I did not give this much thought and held the OTA between my knees, objective to the floor of course, what I did not appreciate was the specs of minute debris which fell onto the glass after completing the process, what a job it was to clean it afterwards, as I had to strip it down again and blow the specs out, in retrospect this should be done with the OTA held the other way up or at least sloping, focuser down, we live and learn, enjoy.
