RE: [APML] 1st BRC mosaic: heart & baby

["Loke Tan" <tan@cox.net>]

Bobby,

 I got my Tak E210 new and supposedly TNR collimated it but it was way off.
I placed an eyepiece to it and the out of focus rings looked completely
squashed. I have been trying to collimate this scope for many months now and
I think I have it right. The BRC would be significantly more challenging.
The hyperbolic secondary makes traditional techniques of collimating not too
useful. Furthermore, you will be sensitive to secondary centering.
