Observing Ladder
After getting the 20", most of my observing now takes place up a ladder. The problem with typical ladders is that the rungs are usually 30cm apart, which means you spend about 50% of your time either stretching or bending over to see in the eyepiece, neither of which is a safe activity when tired and cold in the dark at 2am!!
So I decided to have a go at building a "Half Step" ladder with rungs 15cm apart. Build is basically complete just the bolts attaching the back supports have to be upgraded,a bit more sanding, a coat or 2 of varnish and anti slip tread put on the rungs.
Next part will be a possible chart table to attach to the top.
