- Long Evening/Night session  with 12" LX200 (11 hrs), clear & frosty 
- Session operated in observatory for first hour and then under semi-automated control, with remote monitoring from indoors computer. 
- Ambient Temperature:  -8 deg C  (minimum)
- CCD operation -30 degC (at 50% average cooling).  
- main objectives of the session was to acquire images of selected project stars for ongoing photometric and astrometric analysis
- opportunity taken to acquire several deep sky targets

MACSJ0717 - Massive Galaxy Cluster

MACSJ0717 (Gemimi)
MACSJ0717.5+3745 (MACSJ0717 for short) is a 5.4 billion light years from Earth 
and is one of the most complex galaxy clusters ever seen
http://chandra.harvard.edu/photo/2009/macs

A well publicised composite Chandra X-ray & HST Optical Image of MACSJ0717 
shows the location of hot gas produced by multiple collisions from four separate galaxy clusters

The CCD Image below (total exposure 14 min) taken through 12" LX200 scope shows the 
location of the massive galaxy cluster MACSJ0717 with at least 
10 ?members of the galaxy cluster visible
(with area of Chandra/HST image marked by white square)
