```auto
c = SkyCoord("15h00m00s","-29d00m00s")
c.galactic.to_string
d = SkyCoord("15h00m00s","-29d00m01s")
d.galactic.to_string

```

Both display (334.103, 25.979) and i don’t see how to retrieve more digits to get

```auto
334.1031, 25.9791
334.1029, 25.9788

```

Need 4 digits in mantissa to resolve arcseconds.

You can of course retrieve the components directly (e.g., `c.galactic.l` or `c.galactic.b`) to get the full precision. But, if you’re specifically looking for `to_string()` to show more precision, here are some options:

```python
>>> c.galactic.to_string(precision=8)
'334.10309234 25.97905714'
>>> c.galactic.to_string(style='dms')
'334d06m11.13241986s 25d58m44.60572168s'

```

The `style` keyword is described in [the docstring for `SkyCoord.to_string()`](https://docs.astropy.org/en/stable/api/astropy.coordinates.SkyCoord.html#astropy.coordinates.SkyCoord.to_string). Any other keywords that you supply are passed through to `Angle.to_string()`, and the `precision` keyword is described in [the docstring for `Angle.to_string()`](https://docs.astropy.org/en/stable/api/astropy.coordinates.Angle.html#astropy.coordinates.Angle.to_string).

Thank you, i didn’t dig deep enough into the \*kwargs to find precision.
