Hello,
I have recently done SHO images in short holidays, at places where I could only have wery light setup,namely EQ3-2 as mount, ATIK One as CCD and a Canon EF200 f/2,8 as optics.
It is still possible to obtain good results with only 120 s unguided exposures (IC 1848 and NGC 7000 below in 2 versions, SHO and HA-RGB)

The last one is made with my (more serious) classical setup, 250 f/4 reflector on AZEQ6, Atik One :
