Framing the targets became so much easier with this replacement part.
The default mounting bracked for SGP has two issues:
* you can accidently de-attach your telescope while you try to move it on DEC axisx, so you have to be really careful
* moving on the DEC axis is not accurate: your frame moves when you tighten the mounting bracket
This preplacement fixes both issues for me: it uses separate screws (with screws in the small holes on the side) for attaching the itself to SGP and to tighten it down (the big silver one).
