Hi All

I have been pondering the purchase of a CCD for some time now. I only have one last issue to resolve - mono or osc. On this, I have a question that I was hoping to get answered here.

I have been using my EOS400 for deepsky objects and my dmk21 and QHY5 for planetary. I am comfortable with taking sequences in L,R,G, then B then combining for my planetary shots.

My question is, how much different is combining the four channels for a deepsky object from doing the combining for a planetary? Is the process essentially the same? Is it much more difficult to get the alignment right? If I can do it okay on a planetary, does that suggest I should have no trouble for a DSO?

I am leaning towards a mono.

Thanks
Darrell
