Very happy being the ZWO ecosystem. As an EAA newbie, everything playing nicely together is important.
Will ASI Studio Deep Sky Stacking stack files from different telescope focal lengths? I normally use a 90mm with 540 fl, but may buy a Redcat 51 250mm fl for airline overhead bin travel. Will use the same ZWO ASI533MC pro and everything else. The only change will be the scope. This is a big difference in fl, so it may not work and will not buy it if ASIStudio will not stack these. I use a MacBook AIR. No interest now in getting other software to do this, still learning the basics.
Ok if the narrower field of view is used (90mm scope) and the wider field is cropped accordingly. I would actually prefer this over stretching the narrow FOV.
Thanks
