Replacement Lodestar

Got the replacement Lodestar X2 back from OPT.  It was marked "TESTED" and it appears to work.

Here's a picture of a dark frame.
 Note the low average value.  Also note the bright edge.  Also note the "Star profile" as seen by Maxim.  That's the way a hot pixel should look.

Here's a picture of a light frame.
Note the average ADU level.  Also note that the star profile is flat - indicating that the whole frame is saturated.

Now I just have to attach it to the telescope and get it focused on a real star!
