I do it all the time when I use my oldQ and the QHY8. In my experience you need at least 20 subs and large dithering (5 to 10 pixels). I also use bayer drizzle. It's well worth the time if your image scale is let's say 3 seconds of arc per pixel. DSLR would benefit as well as astrocams. Anything that has a bayer matrix or undersampled mono.
