Horrible!!!

Was so excited to get my AM5 mount, no where does it say to get this app, like you are supposed to get an ASI air to control the mount… so I finally figure out this is the so to control the mount because doesn’t say on the user guide… there is no where explaining hire to align your telescope, the app is so basic you can’t find anything of value in it or direction… completely disappointed

What’s this?

I use this app every night in conjunction with my SeeStar.
I find it very useful

But what’s up with 22 Aquilae?

Good and Bad

App works generally ok but the mapping function for navigation is a massive failure. Extremely limited functionality for screen control e.g. object fonts and search. A1 out of 10 rating especially when compared to Sky Safari!

Sky Atlas update and name change

I am no longer able to use this with my iPad Mini Gen2. It worked fine until this recent update change one month ago. Very disappointed. Some of us cannot all the latest and “greatest” of everything.

Give me back the old version

And name
