Description

324 exposures of 10 seconds
gain 342
sensor temp. -10º

Note the diffraction spikes: 8 branches !!  Why 8 branches while telescope has 4 spider vanes ?
Simple: I collected over two runs of the equatorial table and when I reposition it, the diffraction spikes of the second run don't overlap with those from the first run.
Interesting effect...
