ATIK 428EX - 250mm Relector - Coma Corrector

[Tinker1947]

Would there be a need for a Coma Corrector when using a CCD (428EX Colour) with a Skywatcher 250mm PDS, i know the gap between the Baader MPCC and the Sensor would need to be 55mm, but what i don't know is would it help to have one in the imagine train or just be wasted adapters....Thanks in advance...

Why not just try it without to see how much coma there is?

I have a order for new kit going through with FLO, if it needs a Adapter to make it fit, i would order one there by cutting the waiting time should it help with any coma...mind you tracking down the Baader Adapter that comes with the MPCC kit might be slightly more difficult, FLO will be getting a E-mail i'm thinking. The present Adapter i have is in us with the Lodestar..
