Ah yes the good old film days with 5 minute minimum exposure times to capture anything, no stacking just single images you got to see a few days later. I still use an illuminated reticule to set up my scope but only have a DEC drive so I can only adjust the tracking speed. (the illuminated reticule is great for polar alignment too) Thankfully with DSLR s you only need 20 sec exposures to get reasonable images.
