Only if the seeing will allow it Fahim. There is no point in having a 0.5 arcsec/pixel resolution when the seeing will only allow 2 aresec/pixel. You are sacrificing sensitivity for unachievable resolution. Better to reduce your focal length or increase your pixel size (binning) to increase sensitivity rather than attempt high resolution images.
This is applied to DSO imaging rather than planetary imaging. By using many images as is done with planetary imaging improved resolution can be achieved by interating bits of repeated detail from multiple images.
