Weekend Planets

Weekend Planets and Moon

These images were all taken over the weekend of April 14 & 15. The images of Jupiter, Saturn and Mars are in the correct size ratio. The 2nd photo is a size comparison showing the correct size ratio with the moon. The planet
images were taken using an Imaging Source Video camera and
processed stacking the best 100 (out of 2000)frames.

The telescope used was an Explore Scientific ED127 refractor (5-inch diameter lens) APO and the camera used was an Imaging Source Video camera DFK21AU04.AS. The video was processed using software AutoStakkert which can be downloaded for free.

Mars is much, much closer to Earth than the others.

The size ratio for the planets is correct, same camera and optics used for all of the planets. Mars close approach occurred on April 14th (15.2 arc-seconds) The apparent size of Jupiter and Saturn were 36.9 arc-seconds and 18.5 arc-seconds.

Obvious the ratio is wrong or you used diff mag eye piece for Mars vs Jupiter and Saturn, no way that Mars disc is that size compared to the giants
