Image Train ASI462MC

ausmensan

Hi,
I am trying to connect up an image train to my CPC1100 scope. So far, I have:

ASI462MC
ZWO ADC
ZWO 2 inch filter holder including Hydrogen Alpha and OII filter
I have taken the visual back off, and the diagonal.

What other parts do I need to connect these together? I believe the distance needs to be 55mm? Can you please confirm this, or let me know what I need to do to get a focused image. I can get an image, but the stars are large, which to me, indicates that that the right image train distance is not there yet. Thanks

Whether or not you need 55 mm depends on the flattener or reducer that you use on the CPC1100. If you don't use one then you're all set. Just focus and start shooting.
The backfocus that ZWO claims is "required" is merely a very common value that is used by many flatteners or reducers. They should clarify that statement on their product pages and in the manuals because it is confusing.

Hi, the problem I have, is actually connecting everything together. I have a few more items:

CPC1100
T-Adapter - SCT (Canon EOS) works fine.
ZWO Atmospheric Dispersion Corrector
ZWO Filter Drawer - M42, can connect one side, not the other
UV IR Cut Filter 1.25 inch, have fitted this ok
Celestron f6.3 Reducer Corrector, have fitted this ok after removing the visual back, the diagonal has also been removed
ASI462MC Imager

I guess the issue I have is, do I have to reduce what I use in order to keep it to 55mm, and what spacers do I need to connect each of these components together? Some just connect, some don't. Finally, what order do these items need to go in? I am guessing the F6.3 goes first, connected to where the visual back was, I can connect the camera ok to this, but the other items are problematic.

Not sure why they do not just provide this information when you buy the stuff, or at least tell you what other spacers etc you need to get it working correctly.
