Hi again.
further to my post below:
here is a complimentary data set acquired with this telescope. While this data is very good, it gets even better.
Feel free to download and process and if you plan on signing up for 6 months or more, then send me your processed result to enter a competition. The winner will receive an additional 3 complete data sets acquired with this scope when it was operated from Sierra Remote Observatories in California.
