Ratings and reviews

Celestron SkyPortal Wi-Fi Module

Celestron SkyPortal Wi-Fi Module SKU: 93973-CELESTRON

Rated 5 out of 5 by from Works well! Be careful at zenith. This is a must have for the NexStar series scopes if not for the simple fact of not having to set coordinates and date/time at alignment when used with the SkyPortal app or SkySafari. Not necessarily a fault with SkyPortal Wi-Fi since it's just how the aux ports are designed on the NexStar mount, but once plugged in the scope will hit the SkyPortal Wi-Fi dongle when slewed close to zenith. The good news is there is some flex built into the dongle which prevents damage to the scope or the dongle itself. Setting slew limits would be a good idea or possibly using the aux splitter. Overall great product!
