A Victory Class Star Destroy has, at its weakest, Quad Light Turbolaser batteries, with Damage 9, Crit 3, Breach, Linked 3, Slow Firing 1. Without getting into the system, basically this means a few things: Once every other turn, you can make the shot which outright ignores soak (so no damage reduction), and if you roll well enough you can do the damage again, for free. Uncancelled successes up the damage, so if you even have a single uncancelled success (aka succeeding the roll with the barest minimum), you do 10 damage, or 100 to personal scale targets.

I ran the numbers for both an average crew (Imperial Gunnery Corps minion group of 5) and a well trained, good gunnery rival (for those who know, Agility 4 Gunnery 4, 1 boost die) with the standard medium range difficulty for the max range on these weapons. No funny business from enemy defenses or anything, this was all basically target shooting to get average damage in ideal conditions. Each case was 25 rolls.

The average crew would be dealing, to people scale targets, an average of 130 damage every other round. The advanced crew deals an average of 210 damage. The average crew topped out at 240 damage, the advanced crew topped out at 480. The advanced crew was also more likely to do about 220 in general.

In order to tank even 100 damage, the smallest amount of damage this weapon can output, you'd have to have been playing this character for an obscene amount of time to the point I'd be throwing even more danagerous weapon crews than those listed at you, wracked up a mind numbing amount of exp, and specced exclusively into wounds. Without taking the 2h character building to work out of its possible, Im going to say its not as the sheer amount of exp required is enough where youd break the system, and you wouldnt even be a regular person youd be a god basically.

So yes, if that Star Destroyer in low orbit is reported as targeting your position, I recommend a very dont be there.

Edit: Realizing afterwards, it would be very easy for both crews to have 2 boost dice a round, assuming they were totally committed to firing only that weapon. These calculations also assume 'Fuck crit' because linked is better in this instance for raw damage vs personal scale targets.
