Re: High Resolution H-Alpha Solar Image

Thanks Ivan. After some tinkering, I am now able to produce this quality consistently. For high resloution imaging good seeing condition is essential. Good news is our local seeing condition is good. Next I am trying the next higher resolution with a C11 SCT.
