ATM 6" mirror
Hello
My name is Tony Blakesley, I am 14 years old and I am from Tulsa(Broken
Arrow), Oklahoma. If I go into the rural areas of Oklahoma the skies are
very dark about 5.8 magnitude. I finished my first mirror about a month or
so ago, handmade, and I just recieved from coating 2-3 weeks ago. I set up
my telescope, collimated it, and everything. The images of the moon were
awseome. Then I turned it to a star, Antares(0.92mag), and saw the image as
a stretched star. I then figured I had astigmatism. I don't want to try to
re-polish because I am out of pitch and Cerium Oxide so I am thinking of
either finding or making a corrector lens for astigmatism. Is there anyone
who can help with me on this or is there any other thing that can fix
astigmatism. I believe the astigmatism in my mirror was cause because I did
uneven stroking.
Tony
