Occasional Notes is a publication
not connected with any organisation. I invite contributions on all aspects of
practical astronomy: visual observing, imaging, photometry, spectroscopy,
telescope construction and maintenance, restoration of classic instruments,
observatories, and historical articles particularly relating to instruments. Please
contact me if you would like to receive these free publications directly. All
communications and newsletters are sent ‘bcc’. All
contact details are kept strictly confidential and for my own use only, but
please let me know if you wish to be removed from my private records. Please
contact me if you would like me to present a talk. |
