Need Help identifying this feature on my out of focus star.
Hello all,
I need to know what the odd shaped bumps are on the left hand side of this out of focus star image. I need to see if it's the cause for some odd shaped stars I am getting. They look like peanuts..
The star was Sirius and it had almost just crossed over the Meridian, so it was fairly high.
Thanks for the comments, yes Peter looks like I need to let the mirror cool a little more before attempting this, I thought it was good enough, obviously not.
I think the triangular thing on the Left is the secondary mirror clip. I will be doing a Mirror cell modification to the scope this afternoon so hopefully it will help collimating the mirror better.
