Sub lengths for RGB vs L and Ha

Hi folks 

What's the perceived wisdom on the length (and binning) of RGB subs compared to Luminence and Ha subs, if the L or Ha subs are later to be combined with RGB subs?

Thanks for feedback

Good question! You might do better with this post being in the imaging section, perhaps a mod could move it over there?

My approach is to experiment with some sub lengths and see when the stars start to bleach out. That has tended to be a few minutes long, whereas with Ha subs I try and get 1800s subs. I guess a lot depends on your particular set up.

I generally stick to 1x1 bin, though have experimented with 2x2. I was undecided as to whether there was any advantage with 2x2.

I look forward to seeing what others respond.
