Celestron Nexstar 6se/8se alt az mount and tripod

For sale is my trusty Celestron Nexstar 6se/8se alt az mount and tripod. Will include mini usb model hand controller, talentcell rechargeable battery that will run the mount for a few nights on one charge, a 3d printed mount for the battery, an upgraded level installed on the mount, and a hand Controller mount for the tripod leg. The only issues are a non functional battery compartment and the springs on the top of the tripod are rusty. Which is Stange because there's no rust anywhere else.    This mount works great, and is used for my planetary astrophotography with my 8se. All buttons on hand controller are functional(if you decide to use it), and it works amazing through cpwi. Hand controller alignment kept jupiter in the fov for around an hour with an 8.8mm 82⁰ eyepiece at an outreach event before the event ended. I've had mixed results with goto using the 2 star alignment through the hand controller because of lack of exact gps and most likely not perfectly aligned with ncp. Sometimes it was dead on, other times a small slew was necessary to center the target which was always in fov of a 25mm eyeiece. I've had nearly perfect results using cpwi with a 3 or 4 star alignment. I rarely used the controller due to this. Asking $300 + shipping costs through pirate ship or local meetup in south florida. I'l cover the PayPal fees. buyer covers shipping. Reach out with questions.
