You don't understand where the burden of proof is. It's a photo that was published decades ago, it's up to you to prove it's fake, not for me to prove it's "not fake." Yes, it's a picture, guess what, that's evidence! You don't get the luxury of declaring my evidence is "not credible" simply because you say so. It's evidence from an amateur astronomer with no motive to lie. The burden of proof is on you to prove it's fake, or else accept it.
