Advice for my Esprit 100 and ASI 294MC Pro.

Hi,

I'm hoping someone can lead me out of the dark and into the light please! 

I'm just setting up again after a year or so off grid and have added the ASI 294MC Pro to my Esprit 100. I'm using a Skywatcher field flattener and realise that I need 55mm back focus. 

I've used from the camera unit the 11mm T2 extender followed by the M42 21mm extender, the M42-48 16.5mm extender before the field flattener and the M48 to T2 adapter to the scope itself. 

I just need to know whether I'm on the right tracks or if I'm doing something fundamentally wrong. 

Many thanks in advance.

Sounds about right, 11 + 21 + 16.5 + the 6.5 from the front of the camera to the sensor = 55mm.

Thank you Dave. I added the dims up and got the same but coming from DSLR I wanted to ask more qualified individuals just in case! ?

Thanks again.

Could you post a picture of your camera connected to the scope? I seem to be falling one piece short, the extension rings of the camera don’t fit the flattener on my Esprit 80. My DSLR did fit right on the flattener so it seems odd to have to use both rings..
