Baader Planetarium or Celestron SCT T-Adapter for DSLR imaging

[beka]

Hi Everyone,

Having been an almost purely visual observer, I have decided to try astrophotography with a DSLR. I managed to get a Sony SLT A58 which was the only one easily available from an authorized dealer here in Ethiopia. I now need the adapters for my Celestron CPC 1100 and came across the Ultashort Baader Planetarium 10mm adapter and the Celestron SCT adapters. My questing is taking into consideration the big difference in the lengths of the adapters which one would be better?

Thanks
