Description

More on the continual saga of collimating the Takahashi 180ED. This bright star is centered in IC1318 and provides a window into the Tak mirror. The star is ever so slightly offset to the left in the left image (June 12) and is just about centered in the right image (June16). The FMHWEccentrivity images from PixInsight are provided below the images. My CCDInspector data suggest I need to come back slightly and may have just overshot... The adjustments are 1/64 of a turn of the collimation screws each night.
