On Target for the Horsehead Nebula

Description

First night using a revised version of my telescope setup, here in a backyard of the very small town of Hawker in South Australia (Bortle 1-2) shooting the Horsehead Nebula B33.
My original attempt to automate the focuser on the Takahashi FSQ106N using a PrimaLuce Essato connected to the fine focus knob was an utter failure due to the fine focuser slipping and the poor design of the mechanism on the focuser to stop the fine focuser rotating. So I made a mount for a ZWO EAF and connected to the focuser shaft with a toothed belt and pulley system with a 25-40 reduction. This seemed to work faultlessly. Also I fitted a new WO 50mm guide scope and ZWO 715MC guide camera and this is the first time I was able to try these.
Photo taken with a Nikon Z9, adapted Sigma 20mm f/1.4 FE mount lens.
