![]() 23121 forum posts 1360 photos | Whilst we are chucking numbers around I would like to quote something I posted in 2016 : _____ It is worth noting how small an angle 'one second of arc' really is. As a sanity-check; make a little target with a 1mm wide line on it [when I did this, I just filled-in alternate spaces on a section fom an IKEA paper tape-measure] ... Then view that target at a distance of 206.265 Meters. ... At that distance, 1 second of arc is subtended by 1mm. _____ It’s a nice sunny evening, so off you go to the local park or canal towpath.

what's the doody little display? It's a small OLED like this one. Two for £8.99. Bigger sizes available. Not quite as easy to use as an LCD, though perhaps I should have Read The Flipping Manual! Nnot limited to text because it's a 132x32 graphical display. Dave
