It goes without saying that virtually every single character likely picks up Starsign from Astrology as it's a free +1 stat as well as +2 of the appropriate elemental ATK, on top of functioning with Luminary Element to enable builds that largely make use of one elemental ATK type.

Considering a star sign is generally something that a character would inherently have and is fairly impactful for something 1 Talent point gives, I have two suggestions.

1. Starsign could be a Trait rather than a Talent. While this is basically a nerf to it Astrology could be given something else to perhaps give synergy with Starsign's effect, as right now the two sub-talents Guidance and Stargazer are borderline useless, the former having absolutely no effect in Korvara at the moment  and the latter rarely ever being relevant due to how extremely niche it is.

2. Starsign could be something characters start the game with, without the need to spend a talent point on it.

Personally I think the trait option might be more interesting, as Starsign is about on par with most traits in how much power it provides.

Though just giving it to everyone for free would be ideal either way removing it from Astrology would leave it as a borderline useless talent.

As for Astrology...it needs a lot of work, but a quick suggestion from me would be to alter the two current sub-talents to be more effective in general whilst also changing Astrology from being 2 SP per Talent Point to 1.5 or 1 SP per Talent Point to compensate for the following changes:

1. Guidance - Changed to grant its bonus at night. Grants SR*2 Hit vs Monsters.

Reasoning: Guidance is currently useless in Korvara. Even in Sigrogana spotting traps further only in Spatial dungeons is a questionable investment and rarely if ever becomes relevant. Restricting the bonus to PvE and only at night may seem excessive but we already have Chivalry for an obligatory +Hit Talent that also works on players, sometimes. I could potentially see it working at SR*1 vs players but it'd be an auto-pick for everyone at that point.

2. Stargazer - Changed to grant SR*2% bonus HP/FP regen and SR*1 Physical/Mental Stamina regen at night.

Reasoning: The requirement to be at a campfire to gain the SR*3% HP/FP regen is extremely restrictive, on top of it having to be at night. Relaxing the restriction to be only at night allows it to function on Korvara without the need for campfires. The stamina regen is just so it has a bit of impact even if you're not dedicated to PvE at the moment.

The 1.5 SP per Talent Point cost would better support a 3rd sub talent being added in the future to be maxed with the full 10 points invested in Astrology, assuming Starsign is moved away from it to be a Trait or simply inherent to all characters. Personally I'd suggest the following:

Prominence  (5 rank subtalent)- Dependent on the Starsign chosen, grants SR*5 Elemental Resist to the element of the Starsign and SR*-5 Elemental Resist to an opposing element.
For example:

Mars - Fire Resist/Ice Weakness
Mercury - Ice Resist/Wind Weakness
Saturn - Wind Resist/Earth Weakness
Venus - Earth Resist/Water Weakness
Neptune - Water Resist/Lighting Weakness
Jupiter - Lightning Resist/Fire Weakness
Uranus - Light Resist/Dark Weakness
Pluto - Dark Resist/Light Weakness

Reasoning: Allowing players to lean more into the specialization dictated by their chosen star sign. While gaining significant resistance from a talent is powerful it comes with an equal drawback of weakness to another element. If necessary the weakness could be increased to SR*6 to make it more difficult to ignore with Sanctity or a single piece of the appropriate material to prevent Weak! procs from occuring.

Conversely Prominence could be something else entirely, but the idea is to provide something that helps a character represent greater dedication/resonance with whatever their star sign's element is.

TL;DR

Starsign should either be a trait or just something characters have by default due to how prevalent and impactful it is for a talent

Astrology is an extremely bad talent and sorely needs love to even function on Korvara, and it could be interesting to let it provide greater representation of a character's chosen star sign.
