Alex is a particularly talented amateur radio astronomer - he has sent me one of his latest creations - a 21cm plate Yagi aerial (see my website www.astronomy.me.uk) for photos and further info.

I have started process of mapping Milky Way using this aerial as alternative to my Pharmigan ex-military dipole array.

Results of first 2 days at 77 degrees elevation from Lichfield (just north of Birmingham, UK) - see attached graph. Some excellent peaks as drift scan crosses Milky Way!

Anyone interested in finding out more about how to map the Milky Way themselves should come along to my talk at the International Astronomy Show this year.
