Thanks.
I am convinced from all my measuremnts that the sensor needs to be 5.5 mm closer to the flattener..I think Micheal did not get it right notwithstanding he tried...It seems to need a different fitting and hopefully we will sort it out on Monday.
I tried the scope without the flattener and all I can say is it was hopeless with elongated stars almost to the center of the capture...
It will work out I hope.
But such a nice size scope..so much easier to manage than the 8 inch.
