ASI224MC Cooled or not?

I have started to try to capture small DSOs with short exposures using the ASI224MC.

I was wondering if the cooled version of the ASI224MC would give better results and how it would affect the way that you image DSOs. Could the ASI224MC cool be used for long exposure imaging of DSOs?

I would be using it with either a SW ED80 DSPro or a SW 120ED DSPro.

Anyone tried long exposures with the cooled version? Any example images to share?

cooled version can help reduce dark current

so it always helps with DSO imaging

So how long can the exposures be with the cooled version?

As I have had no replies I think that I can conclude that nobody is taking long exposures. So I may as well just stick to short exposures with my 224MC.

Those cameras work good if not better when taking more short exposed frames. I have cooled 178MM and I didn't yet had the chance to test it well on DS imaging. Likely I'll use in the end 1-3 min exposures.

Thanks for the input. I am now convinced that there is little point in getting the cooled version of the 224. I just work with my uncooled version.
