I have a slow Schmidt-Cassegrain with Alt-Az mount, 235mm F10 scope and use a 6.3 reducer with my CCD camera. I use no guiding and short exposure of less than 100 secs. I discovered StarTools and my photos are now amazing. Thank you StarTools for turning my average photos into amazing ones.
Once all issues are fixed, launch AutoDev again and tell it to 'redo' the stretch.
You may have to configure your operating system to not scale up StarTools.
StarTools works on all 32-bit (NT-based) and 64-bit versions of Windows.
High-resolution data sets, such as those from a DSLR typically require at least 4Gb of RAM.
You can convert everything you see to a format you find convenient. Give it a try!
