I have the T-ring and adaptor but currently trying to get the guide scope and as you know everyone is short on supplies. I was looking at an Orion 50mm with helical focuser and a ZWO 120MC but still can't get my hands on one. Trying to keep it small as I already have heaps of weight on the mount. Soon I will commence building an observatory with a pier which should help somewhat on stabilizing. I believe I will also require a coma corrector which should give me exactly 55mm for the DSLR focusing. Are all coma corrector's the same thickness or is there a particular one I should use?
Cheers

Rod,
Ive have many coma corrector's which I use on my 6" , 8" and 12' Newts
Bintel GSO 2" Coma Corrector
Skywatcher F5 Coma Corrector
Televue Paracorr Type 2 2" Coma Corrector
Baader MPCC MkIII coma Corrector
For my visual work you cannot beat the performance of the Televue Paracorr Type 2
For Astrophotography you cannot beat the performance of the Baader MPCC MkIII
The Baader MPCC screws straight into your Canon T Ring and then pop the DSLR with Coma Corrector into your 2" focuser
Eliminates coma at f5 right to the edge of field , its a proven performer world wide , IF YOU CAN GET YOUR HANDS ON ONE !!!!!
Cheers
Martin
