Thank you all for kind comments...
The processing of this image was minimal:
The stacking was done in DSS (with two darks) , and then I just stretched the resulting tiff image in Canon's DPP such that the details showed up sufficiently - this was necessary work around because stacked Tiff image is 16bits, and 400D's ADC resolution is 12 bits.... And downsizing (original is 12MB)
The rest of it is just the mount with tracking, the lens (relatively cheap Itorex 28mm f2.8) and 400D....
