Ps:
Sorry, forgot to mention that if the astigmatism is due to pinched optics the stellar image would appear triangular in shape. Once again don't worry too much, just enjoy the views.
Cats love reflecting telescopes, years ago our old cat once slept on the mirror of my old 8inch scope, open tube job. I now own a 10 inch scope, our latest cat hangs around it, loves to rub herself on the Dob mount and climb into the rocker box.
Let's hope the the skies are clear for you tonight.
