Part 4 - Assembling the Hardware
The assembling of a permanent observatory either with roof or without, you still require a considerable of equipment. The mount will be the main whereby you would have to build around it.
The AP mount 1100GTO is an excellent mount for precision astrophotography. This particular mount does not include the Absolute Encoders. AE are the latest technology in precision guilding.On axis encoders have many advantages, they should not be considered a panacea for taking long unguided photos. External factors such as optical tubes that bend and differential refraction that conspire to degrade pointing and tracking accuracy cannot be fixed with on axis encoders.
The Mount would need a pier to hold it steady and strongly fixed, I decided on a 8" diameter steel pier with a top movable flange to avoid complication when the mount is fixed on.
This is the top flange with the AP adaptor that will hold the AP mount
I also included a tray for the mount.
Finally the RAPA polar alignment scope.
The final setup with all the units assembled.
Apart from the setup, there are all the bits & pieces that will assist me to control better the mount.
