Last night I used my Canon 60 DA and did 40, five second images on a tripod with a 40mm lens aimed at Orion. I later calibrated, registered and stacked them using PixInsight. I need to try this with longer exposures and tracking but I was curious to see what I could get. M42 resolved nicely. Hereâs a link to the image.
