- F6.3 focal reducer added to optical train, to take system down to around f6.3 (2.62 arc secs per pixel at 2x2 binning).
- BRVI filters added to filter wheel in place of RGB filters
- Objective of session was to check out the updated optical train in preparation for future attempt to detect the extra-solar planet around HD 209458 (next eclipse due on 2005-08-12,   clouds permitting !)
- Acquired reference images of HD 209458 (15s exposure through V Band Filter) 
- Acquired images showing motion of NEO 1992 UY4, which is currently passing close to Earth (approaches to 16 LD on 2005-08-08)
- Attempted to acquire images of new "10th Planet" (2003 UB313), but deteriorating sky conditions prevented getting images with sufficient magnitude reach.

- More Notes (including Temporary Frost Effect in CCD Camera)

MPL 2003 UB313 Attempt - Kuiper Belt Object

2003 UB313 Attempt
Predicted Position of 2003UB313 marked by red circle. 
Deteriorating sky conditions unfortunately
 limited the magnitude reach of the image to around +16.5 
and gave no hope of being able to see this 19th magnitude 
Kuiper Belt object, which lies at 97 AU distance and 
has recently been proposed as the 10th Planet.

2 min exposure, C Filter
