CPC 800 deluxe and macbook pro and skysafari telescope control and mac screen sharing

I ned to know if the above equipment can work so I can control my MacBook from my iMac inside with screen sharing while running sky safari on my MacBook pro at the scope outside. The issue is wifi, as it appears the MacBook needs to wifi connect to the skyfi 3 , by doing so it will not be connected to my apple router thus no screen sharing. It seems that if I could connect the skyfi 3 as an access point on my apple network then I could both screen share and control the skyfi 3 ??  I have tried this with the celestron wifi module and it will not connect as an access point, despite its manual saying it supports it. Then i would plan to also be running nebulosity on the MacBook for image capture.

    Brent,

    The SkyF 3 should be able to connect to your home network via Access Point mode.  The Celestron Wi-Fi module should as well (and I've tested this many times).

    This should all work, but I can't guarantee performance with the additional screen sharing lag thrown in.  You would just have to try it.

    As an additional note, I've just had a report from another customer that Access Point mode using the Celestron Wi-Fi adapter (SkyQ Link or SkyPortal Wi-FI module) doesn't work if the SSID (network name) has a space in it.  I haven't verified this and it is not a Simulation Curriculum problem.  I just thought I'd mention it since it wasn't working for you.

    thanks for quick reply. I spent a few hours trying to get the celestron wifi access point to work and could not. I did read about the ssid name and spaces and still no go. would sky safari 5 for mac OS X also work with the star sense  feature ? as I understand it, sky safari on the mac would have to perform the star sense auto align for it to know how/where to point the scope for goto's...

     

    another issue with the celestron wifi is it has a very short range, so even if i could get access point to work its range might not be compatible in my backyard to my router inside, would the skyfi 3 be expected to have adequate range for such a setup ??

    Brent,

    The Mac version of SkySafari does not support StarSense alignment when connected via Celestron Wi-Fi.  On Mac you have to do the StarSense alignment using the hand controller and then connect via a cable plugged into the hand controller.

    SkyFi 3 has a range of around 100 yards in an open field.  If you are going through house walls it will be less but should still work.

    hmmmm....so what is the cable plugged into the hand controller plugged into opposite the end of the hand controller ??

    I guess if there was a way to connect my MacBook to the star sense hand controller with a wire there would be no need for the wifi module ?? is there such a solution ?

    Yes,  you just use a Celestron serial cable from the hand controller to a USB-to-RS232 adapter (KeySpan is the one I recommend).  The adapter is plugged into a USB port on the Mac.

    We sell the serial cable on our store.  One might have come with the mount.  Note that a generic serial cable will likely not work.  Every manufacturer wires their cables differently.

    ok I see. celestron also has a usb to serial cable but not sure if it is mac compatible because it has windows drivers. This would be a good solution I think. I would need sky safari 5 for mac, with usb to serial then serial to star sense hand control. setup scope and do an alignment with the star sense hand control, then I could control the scope with the sky safari application on the MacBook. this would free up the MacBook wifi for screen sharing back to my iMac. 

     

    does sky safari for iOS support star sense with celestron wifi ?

    Your proposed setup sounds fine.  I'm surprised the Celestron adapter doesn't have Mac drivers.  You might check on their support site.

     

    Yes, the iOS version can talk to the Celestron Wi-Fi unit and run a StarSense alignment.  No need to do it through the hand controller.  In fact if you do the alignment both ways, the two will conflict with each other, giving random results.
