Notes/ Conditions |
Conditions- After a very hot
day of 41deg C, the evening didn't cool down to well into the morning. It
took a long time for the optics to settle when taking the lum and was
difficult obtaining good focus. Things settled through the rgb's. This is the first image
taken on the CI700 mount. Image has been reduced to 80%. |
