Subject: ETX90RA, Daylight Ganymede transit ...... Sent: Monday, May 12, 2003 15:13:06 From: email@example.com (martyn) Last saturday there was a transit of Ganymede, one of the moons of Jupiter was crossing the face of Jupiter....during the day! I was following this daylight-event through my larger Maksutov(MK67) from about 18:15h DST local(Netherlands). At 20:10h Ganymede had passed the central meridian and showed as a very dark spot against the equatorial zone of Jupiter, just north of the SEB. I decided to try this with the ETX90. It also showed Ganymede quite nicely at 195x with the SP6.4mm eyepiece as a dark spot. Higher and lower powers were less successful but the 6.4 showed Ganymede very well in front of Jupiter during full daylight! regards, martyn Netherlands
