Much to my great relief my attempt to re-collimate the second Sky 90 (which had somehow lost its good collimation) was successful. And on top of that we had clear skies last night for me to test the imaging results and to start the next laborious task of flattening the CCD chip to the scope optics. During the chip flattening process for which I use the totally invaluable CCDInspector – I actually hit the magic 0.0″ collimation on the re-collimated scope. Unbelievable!! I have never before seen the magic 0.0″ collimation using CCDInspector on a Sky 90 before. So for the moment at least, things seem to be moving in the right direction 🙂
The next major tuning jobs to undertake are to get both M26C cameras as flat and as well-collimated as possible – then it’s over to some serious deep-sky imaging with the mini-WASP array in mosaic mode – probably by then in the Cygnus region imaging all those H-alpha goodies. 4 x 3.33 degrees field of view at 3 arc seconds per pixel of yummy goodness 🙂 🙂
