For deep space (which is what you are attempting here) you need long exposures and consequently good tracking.

Right, I understand that now

Anything much less than 5 min subs for DS is just temporary progress. Stacking really short subs is just hard work, you need to overcome read noise with longer exposures. I see many ppl making tiresome incremental improvements with short exposure times/huge stacking and just tracking, get the fundamentals right (polar align and guiding, do it now, dont waste time) and youll be supprised at the results.

I will. Promise not to post again till I have the tracking right.

That's right, not aiming for planetary yet
Thanks for all your help guys.......
