Re: [APML] First light with FSQ

[lkt <tan@cox.net>]

Alan,

 I think this is due to the slight restriction in the bayonet mount of
your camera-to-scope attachment. I have seen this everytime I am using
the Pentax6x7 with a Tak FSQ and also to a much lesser degree with some
AP scopes. To get rid of this, you will need to use a camera such as the
Mitsuboshi 6x9  or others with a wide throat connecting the camera to
the scope.

If you look at my way-over-processed, much-crummier version of the same target, taken with my Tak FS102, you will notice the same dark lines on opposite sides of the halo on the bright star off the coast of Northern California/Oregon (obviously I don't know the name of the star).  Do you, or anybody else who happens to be reading, know what causes this effect on the Tak scopes?  The image is at http://home.gwi.net/~aljordan/astro/naNeb.html
