Hello? I use the STL-11k mono. It have many vertical streaks(file attached, Bias and Dark). Of course, it can be neutralized by dark and bias substractions.(not completely, attacted file, Maxim) Questions: 1. Are there any method to correct the vertical streaks completely?(software? or something else methods?) 2. Can I fix thoroughly this by board changes or some by SBIG? How much does it cost(mail please), if possible? Thanks Richard M
Richard, could you also send those images in sbig file format to Alan Holmes and ask him for his opinion ? His email is : alanh@sbig.com Regards, Jan
I had that problem with an STL: 11000M. I found that properly temperature calibrated dark frames got rid of nearly all of it. Picfix.exe freeware from Focalpointe observatory gets rid of the rest.
Hi Richard, I missed your call, I had to run out a couple of hours ago. If you don't call back tonight I will call you in the morning. Cheers Tim
