David's Astronomy Pages CCD Images - Session 85 (2005-05-10) Images (S84)   Images (Main)   Home Page   Images (S86)

Notes (S00085)

- 1.1/4 hour imaging session 
- main observing target was Jupiter which was image at f/22 with a barlow
- seeing conditions were fairly poor with unsteady atmosphere (see sequence of images of Ganymede)
- attempts to record deep-sky images in Virgo were cut short due to dew formation on the front lens of telescope (I'd forgotten to attach the dew shield and hadn't started dew heater sufficiently early).

Jupiter Moons

Jupiter + Europa  (Europa is about to be occulted - at 22:50h UT)

CCD Image, 0.2s exposure, clear filter 2005-05-10  22:38 h UT (#85082)

Europa just before point of occulation

CCD  Image,  2 sec exposure, clear filter  2005-05-10  22:47 h UT (#85114)

Jupiter + Io & Ganymede Amalthea also lies within the field between Jupiter & Ganymede,  but at magnitude +14 it is is not visible in this short exposure (an even in a long exposure it is likely to be lost in the glare from Jupiter, mag -2.3)

CCD Image  0.4 sec exposure, clear filter 2005-05-10  22:56 h UT (#85154)
