I have been waiting for an Astronomik 2" 10nm Halpha filter. It arrived today at Bintel in Melb. and Roger Davis kindly DELIVERED it to my home tonight. It is now safely installed in the Canon 300mm F2.8L ( after a slight mod ) waiting for the Sun to set. I don't think I could have waited through a public holiday with clear skies as I was unable to pick it up.
I can now take images when the Moon is up
Will post some images later.
Thanks Roger and Bintel.
