User reviews

Will no longer connect or align

It appears that the Scope feature is no longer working so you’re no longer able to align or connect to the SkyPortal Network.

Perfectly neat

Everything in this app is so tidy and it doesn’t show too many stars from further distances like with other apps it shows stars you can even see from earth and just makes it overcomplicated when looking for a certain star most certainly deserves a 5 star rating

Awful

Truly one of the single worst, least intuitive, least user friendly apps I’ve ever had the misfortune of being forced to use.

Quite a bit inaccurate on determining the location of planets, stars, nebulas, and etc.

I’ve tried to get my telescope centered using this app by aligning it to the moon’s location, and I’m being dissatisfied by the app’s performance as when I tried to aligning the telescope through the app, the lens showed a blank sky because the telescope was offset to the right of the telescope’s direction of focus. I had to literally manually align the telescope due to this. I do have a screenshot of what I am speaking of. Finding planets took me time because of a similar scenario. It would be great if the app could make improvements with aligning the iPhone so that telescope users won’t have to turn on their battery powered laser that comes with their StarSense explorer telescopes or any other telescope of this brand.
