This one was with the extension tube...........
This gives me about 8.7x f6 x 1500mm = 13000mm.
Due to less light, i had to drop to 15fps and carefully keep the 320px joop on the 480px screen
Comparing this to the earlier one @ F39, you can see the beauty of the 5x powermate and its ability to adjust with the length of extension.
I have included two images, one with the usual data, plus one with some features labelled. I am slowly coming to grips with the zones and bands and spots and barges etc etc
