I already spotted Jupiter last month, and that's the first time I observed Jupiter with my orion XT10. I can tell the Jupiter is so small through my 25mm eyepiece.
On 18th of September 2010, 2days after I come back from Malaysia for summer holiday, I observed Jupiter with anwar, abg rizal and azizul in anwar's backyard, Jupiter is near the opposition, and I can tell' its looks bigger through my eyepiece than a month ago. Before I arrived in Birmingham, I did order Celestron Omni 2x Barlow lens so I can double the magnification of my eyepiece. And Its works really well!!!!However, because of the opposition, I prefer to use my 25mm eyepiece without barlow(Jupiter is already bigger than usual)
Many people said that Jupiter's great red spot can be observed easily using 6inch or 8 inch telescope during the opposition. However, Its kind of hard for me to find the red spot during its transit in 19th September, probably because of the seeing condition. I observed Jupiter and Io transit with abg rizal, and kak ainol that night. It was the first time I observed Io transit and I never observed any other moon transit before and, its beautiful.
While I'm writing this entry, I can see Jupiter from my window where it's just 591518236.68846 km away/3.95405177AU from earth..and my telescope is 194.9km from meT.T
