My ADC needed a good cleaning so I disassembled it to access the prism. No problem until reassembly time, I lost track of the direction of the prism. On each prism, one side shows the glue while the other side is flat. How should they be facing? Both side with glue together? Both flat side together? Both flat side facing in? Both flat facing out? Your manual does not mention. Thanks

Hello there;
I’m going to use it in conjunction with scientific explorer telextender barloms.
How would your coupling be?
Barlom- Correptor_ Camera 462MC?
How many mm of extra focus outside the eyepiece holder to direct focus is needed?
Greetings.

Hola;
Cuantos mm de extrafoco se necesita en mi telescopio para poder usarlo.
Se usaría despues de las barloms explorer telextender de x2, x3 y x5 con una camara asi462mc.
Actualmente el estrafoco es de 34mm por encima del portaocular de perfil bajo.
¿Podria usarlo sin problemas de foco?
Saludos.

From the diagram, I see the body, not including the holder & nose-piece is 29.4mm. What is the optical length of the body once factoring the glass in the device? I’m trying to calculate the impact to the optimal backfocus distance by adding this to my imaging setup. Thanks!

Hi again guys,
I needed to carefully clean my ZWO ADC because of dust motes (even though it was new). I had no problem cleaning and re-assembling but I wonder if I could have installed one or both of the lenses wrong/backwards? Does it matter? Is there a coating on one side The reason I ask is that the adjustment angles with the levers seems a little odd and extreme when reducing the RGB mis-alignment…
All the best

If it is placed in the wrong way it will have impact.

Btw, I’m getting an ASIAIR next week and am VERY excited about the features! I’m especially looking forward to the Polar Alignment routine and the Nikon DSLR connectivity as well as for using my ASI071, etc. Thank you very much for all the hard work in creating such a useful imaging tool and thanks for listening to your customers requests and suggestions.

Hi James,
We have a document about how to clean the ADC, if it is place in a wrong way it will have impacts.

Is there an adapter to attach my 290mc to the ADC? I would like to remove the eyepiece holder if possible. I need to reduce back focus so I can use an external focuser on my C9.25. Thanks

Sean Wang – :
Hi Tim
Don’t worry about back focus of C9.25, even add a external focuser, it won’t be a problem. I recommend keep eyepiece holder on ADC, if you insist to take it off, you will need a T2-T2 adapter to connect the ADC body with camera body.
