    Default Sky-Watcher StarTravel 102 Modification?



    I'm considering buying a Sky-Watcher StarTravel 102 OTA.

    Screenshot 2018-01-23 at 20.00.48.png

    Removing the stock focuser and replacing it with either of these:

    TS Optics/GSO Crayford monorail
    Screenshot 2018-01-23 at 20.09.17.png

    or

    OVL/Synta Crayford
    Screenshot 2018-01-23 at 20.42.37.png

    I'll probably go with the TS Optics. Has anyone done this modification with an ST102, if so, how did it go and were there any problems?

    Thanks

    You'll want the one with the 96.6mm adapter compared to the 86.4mm that your ST80 uses. Should be just as straight forward as the swap for the ST80. Three screws, get it squared, and tighten it down. Toss in a collimation cap to make sure you are true, and off you go.

    I like that. Why is it Skywatcher US seems to have no equivalent on this side of the pond?

    Yes, I know it's a different sized focuser. The Synta looks nice but I'll probably stick with the GSO. Thanks.

    There's probably an Orion equivalent, they market a lot of Synta scopes.

    I think Sky-Watcher (basically Synta's trading name) is well established in Canada. It's Commonwealth but I wouldn't have thought import expenses would be that bad to the States.

    Since I do AP with my SkyWatcher 100ED, I put the 96.6mm Linear Bearing Focuser on board.

    Yes, that's the one, I think it's better than the Synta one. I can get one locally though, the last time I ordered something from Agena the Royal Mail lost it at Heathrow.
