Stan. I am unable to to accurately align images with any method in my version. Without exception I have to finish off using manually fine align which is extremely tedious and time-consuming. I use a scope/CCD with a 0.58 arcsec image scale and typically I need to stack 12 - 30 ST-11K images at a time. I use Vista Home Premium 64 to run CCDStack. I have read your advice on previous postings but applying these does not solve the problem. Can you help? Jan.

Hi Jan,

Please contact me (stan_ccd at yahoo dot com) to send at least 2 frames that fail to align (the reference/base and a target frame).
