Fitted baffle to 130PDS, do I now have pinched optics?

[BrendanC]

Hi all,

I fitted one of these recently. It's a baffle, for hiding the primary mirror clips and hopefully improving the clarity of my stars. 

However, on testing it by taking shots before and after of Vega, I'm underwhelmed.

Also, in my latest shot of M11, there's clearly something wrong with the two stars to the right (the blue and yellow one - the only ones bright enough to display diffraction spikes). They seem to be bleeding/bloating out bottom right.

Here they are unstretched - odd shapes.

So, have I overtightened the screws on the primary mirror when fitting the baffle? They were pretty tight to begin with (never removed them before). I've since loosened them by checking a card fits under them as per this video: https://www.youtube.com/watch?v=EOFYyhkwG_Y

However, given that even a half decent night is quite some way away for checking whether this is fixed, could anyone who knows about this sort of thing give me their take on what's going on here?

Thanks, Brendan
