Eyepieces: 25mm, 17mm, and 
10mm 
Magnification: 		 A bit out of order. Appears in low power FOV at the apex of a rather flattened, almost scalene triagnle. I was able to ID these as: to the W, SAO 92232 and to the E, SAO 92243. Visual estimate of the PA:200°. Color: blue and perhaps dusky orange.

with 1.7X TeleVue barlow. - PA estimates
noted below are using this eyepiece.
Magnification: 106x, 212x, 272x, 270x		 seemed much wider than what was catalogued, I made some measures with the astrometric eyepiece and will report back. Estimated at about 16". easy in the 18mm at 106X.
