Fails to connect too often.

Amazing when it connects. Useless when it doesn’t. Why is it built to be so hard to connect to the telescope?

Catalogue missing many objects

Why the Seestar has the C/2025 A6 and Unistellar does not?? I have both telescopes but finding myself using(and recommending) the Seestar much more. This is junk, clunky app and connection, lack of features (compared to Seestar)
