How to Build an Observatory for Astrophotography Pt4 (concrete slab base)

In this video I continue with my build removing the shuttering and rendering the side of the slab to stop the rubble escaping from underneath.
After a bit of tidying I acyually start building the office. Unfortunately not getting as much done as I would have liked as the weather has been really bad.

ProLogik balance meter and tuning tool
https://www.prologik-astro.com/

The meter is of a high quality and works really well. Not only is it great for helping to find perfect balance in stiff mounts but it is a fantastic aid to fine tuning your mount for the best guiding. It will assist you in adjusting your worm drive/gear mesh to the optimum setting and giving you great smooth tracking and excellent guiding numbers.
