Just an update .....
After using my custom designed Dome rotation control system over the past 2 weeks or so , the only limitation or weakness in the design using azimuth movement is when your imaging up towards the zenith approaching the meridian ( +70 degrees)
I found that azimuth movement to keep the scope centred in the dome opening could no longer work and a 180 degree manual rotation of the dome was required to keep the scope centred in the opening and tracking clear with some very small manual adjustments of rotation until the object past the meridian and started to ascend again
Other than that it’s working really well. Imaging M83 the other week only required intervention after 3 hours , just a minor manual tweak
Last week I was imaging the Prawn nebula for nearly 4 hours and only required one small manual tweak
It’s not fully automated ( I never wanted that anyway) but it sure beats checking the Domes position every 15 to 20 minutes if it was totally manual
If anyone’s interested, thanks for reading .....
Comments welcome
