Camera Tilt

[Sunfish (Ray)]

Same again with f5.9 reducer this time for a wider field .

You can see that I have some camera tilt as the Bahtinov focus differs at the bottom on the single sub. A loose grub screw in the T adapter I think.

A new adapter too.

Yeah a slight tilt, still a great image Ray. When I put my mask on I check all the corners to see how not only collimation but also tilt.

How would the bahtinov show up collimation problems in the corners?. Simply focus? May be useful for the SCT rather than this refractor. I have only dealt with centred stars for collimation.
