Use another camera than the guiding head on STL11000M ?

    I am using the STL11000M+AOL+Sbig guiding head.
    But as the sensor pof the guiding head camera is small, I would like to know if I can connect on the STL11000M another compatible SBIG camera with a bigger sensor (may be using an electrical adapter).
    I am using an AO-L that I still want to use, this is the condition.

    Can you help me telling me if it can be done, otherwise, does it exist an electrical adapter to connect another camera on the STL11000M.

    Regards

    Hello Franck,
    No, the STL-11000M remote guide head port cannot be used that way.
    Instead, you could try something like this: STL to SBIG StarChaser SC with an adapter and the AO-X.
    Here's an article on this:
    https://diffractionlimited.com/stl-camera-new-tricks/
    In this setup, the SC controls the AO, and there is no electrical connection to the STL, just a mechanical adapter like this:

    Some customers also have used an Astrodon MOAG device similar to this, which holds a different guide camera, but you can't control the AO:

    Thank you for your reply but I don't need a starchaser or a MOAG, I only look for the possibility to use a compatible SBIG external guiding camera which would work with the AOL.
    I am using the STL11000M+MOAG with the guiding head + AO-L.

    But I would like to change for this configuration:
    STL11000M+ONAG+AOL and using in the optical axis a guiding head camera with a bigger sensor.

    Are you trying to use one of these?
    https://www.innovationsforesight.com/product-category/on-axis-guider/

    We don't have a guiding head camera that plugs into the STL and controls the AO-L.
    Use a separate SBIG USB camera as the guide head.
    The second SBIG camera woud have it's own I2C AUX port to control the AO-L.
    You would have to design your own mechanical adapters.


    You might find something like a used STF-8300 somewhere cheap. We sold out, because ON Semiconductor, maker of the former Kodak CCD detector chips stopped making those parts in 2019.

    Or you might try a STC-428-OEM with an adapter cable to the AO-L. We've never tried that combination.

    Yes I would like to use an ONAG and I am a mechanical engineer so it's not a problem to design an adapter.

    Just find another SBIG camera that has an I2C AUX port and you're done.

    Fantastic.
    Would you have a list of old cameras to give me that have a I2C port?

    I suggest you talk to Gaston at IF for his recommendations, to make sure it will all work together.
    Most models such as the STT/STF/STXL/STX would probably work. USB versions of the ST7/8/9/10/2000 would probably work but are really slow downloading - except once you find the guide star.
    Aluma CCD and other newer models that have the round I2C AUX port probably would work.
    I can't guarantee this.

    Thanks a lot Colin. I am in contact with Gaston, waiting for a quotation with all the mechanical adapters needed.
