HD209458 (star to extra-solar planet system)

HD 209458 has a transiting Jupiter mass short period extrasolar planet.(HD 209458-b). Every 3.5 days, the planet produces a dimming of the star of 1.7 % that lasts for about 3 hours. The dimming has been detected by Castellano and Laughlin using almost identical equipment to me (ie 8" telescope and ST-7E CCD camera), which presents me the opportunity to me to also have a go at trying to detect a extrasolar planet lying at a distance of  1.45 x 10¹⁵ km (47.08 parsecs, 153.5 light years) from Earth..

As a prelude to a future attempt to detect the planet an initial image of HD 209458 was taken :
