• Dome Flat | |
to calibrate CCD images with Dome Flat illumination
system, installed during our visit at Kottamia in Nov. 2010.
High resolution graphs , used in the PDF report, are available in another page (html). A list of CCD frames is in text file, available as 0Obslist20101114_SkyFlat.txt . Originally SORIC screen was planed to be used as reflecting screen.
SORICSCREEN are made by STELLAR OPTICS RESEARCH INTERNATIONAL CORPORATION (SORIC) , and treated in Japan by Cornes-Dodwell Co. |
|
• CO2 Snow | |
to clean up the mirror surface from the accumulated dusts
|
• Hartmann Test | |||||||||||||||||
to evaluate optical performance of the telescope using Hartmann Plate Hartmann test during June, 2009
Hartmann test should be done again after optical adjustment.
|
|||||||||||||||||
•
Hartmann test during Nov, 2009 Image quality has been much improved after adjustment of heights of Axial Support System.
