That's what I'm talking about! Do I need a Windows based PC for processing? I'm all Apple right now.
Alright bro I'm going to sideline you for just a minute here. I am the same way...I totally get it.
However....There is a BIG difference in learning curve between a DSLR/cooled OSC camera as a total greenhorn, and a Cooled Mono cam with filters. Check my sig...I have a lot of the above mentioned gear...your results will be leaps and bound above a DSLR with a mono cam...but i'm telling you the processing, and acquisition is SO DIFFERENT (IE more challenging). DSLR/OSC you setup and shoot one. Mono you have to shoot for every filter, then combine it all in processing. There's a lot more to go wrong and to understand. You better have guiding figured out, as well as focusing as you'll need to re-focus constantly. Again OSC you focus once, point and shoot. It's the cooling you would benefit from as a newbie...not the mono/filter combo until you truly understand what you're doing.
I'm going to take his list and make a couple adjustments purely so that you don't find yourself abandoning the hobby out of frustration trying to jump straight into monochrome imaging with filters and the processing involved.
