Viewed Saturn for the first time. It was amazing! I had never seen Saturn's rings except in pictures. I also looked at Sirius, Betelguese and Mars. I was a little disappointed with Mars. Is this a bad viewing time for Mars? I was kind of hoping to be able to see the polar ice caps but all I saw was an orange ball. The scope only came with the 10 and 25 mm eyepieces. The 10 takes it out to 120x. Would a good 2x barlow lens be a useful purchase? If so what does everyone recommend?
