MaxIm DL Version 6.25 is now available. Select Help menu Check For Updates to download. Release Notes: Remove Bad Pixels: Added a new option to zero out the bad pixels. When used in conjunction with the Stack command's Ignore Black Pixels feature, this will significantly improve suppression of hot columns etc. SBIG w/AO: Added window heater control. Screen Stretch Window: Fixed a minor bug that occasionally impacted histogram display. Observatory Control: Fixed a bug that caused slew refinement to always engage, instead of being performed only on long slews. Camera Control: Fixed an intermittent timeout problem when fetching images. Users of SBIG DL Imaging cameras are recommended to also update the DL Imaging drivers, and the DL Imaging ASCOM driver.
