What I find hilarious are comments that they couldn't do some of those effects in the 60s so they shouldn't be in this. So wrongheaded it a joke.
RAMA
I don't want to drag this thread too far off-topic, but this does touch on a core issue regarding the STC series.
From the beginning STC asserted they wanted to recreate the feeling of TOS episodes produced in the late 1960s. They wanted their episodes to look, sound and feel as authentic as possible. To really do that would mean having an incomplete
Enterprise model and limited f/x shots. It would also mean avoid references to productions made after TOS ceased production.
Now in fairness we know the TOS production crew would have loved to do more, but were constrained by limited time and money. But if they had had that extra time and money we can see examples of the era to give us an idea of what was possible given the resources of the period. Flash forward fifty years and a fan production has the resources to realize things that were out of TOS' reach in terms of time and money but not necessarily resources. So they can show us things that could have been done under ideal conditions.
From the beginning productions like STC have not faithfully adhered to the idea of being a totally faithful recreation of TOS. The most obvious example is the inability to resist inserting references to post TOS productions. The producers of these productions are, after all, just as much devoted fans as any of us and it's understandable they cannot resist the temptation to express some fannish aspects.
Fan productions can also blur the line between what might have been possible and what could have looked "cool." I don't think I've seen any fan production not cross that line at some point and to some extent. But that said we must recognize that TOS could have done a lot more than what we saw if we allow the conceit of added available time and money.
And this is where a production like STC comes in who often try to show us something new and usually try to remain faithful to the idea of what could have been possible in some fashion back in the late 1960s. It might not have looked quite as seamless or quite as polished as today's f/x, but it could have realized a similar end result.
