Location of site: Annen, The Netherlands, 53N 6E
Site classification: Suburban
Sky darkness:
Telescope: AP Starfire 5' f/6
Mount: Losmandy G-11
Eyepieces: Pentax 40mm, Nagler 12mm, Nagler 9mm + TV powermate 2x
Magnification: 40x, 97x, 135x		 Located near Iota Boo this pair is easy to find, just inside the same FOV with 40x. 40x is enough to show STF1814 as a pair of two somewhat faint stars. This low power gives the best impression of color: A yellowish and B light-orange. Using 97x gives the best view, the subtle pair easy to see and sitting in a field with quite a bit of other stars. 135x makes the pair too wide and also a bit faint.
