How to capture DSO with ASI120 ?

[Kakadush]

Hello  

This is more of a DSO question but i figured this section of the forum has the most experienced people with the ASI 120 cam so i posted it here , i hope that's ok. 

So i've seen some people experimenting with DSO photography with the ZWO webcams and getting some decent results and i would like to give it try can any one give me some pointers ? i really dont know where to begin. 

* What capture software should i use ? is firecapture ok ? 

* How do i keep my cam's shutter open for exposure shots ? do i need some sort of cable ? 

* Is it possible to stack the images using AS!2 ? or is there a better software to do that with DSO (Nebulosity ?) .

Any pointers would be greatly appriciated , thank you !

FireCapture can allow exposures of up to one hour according to this page. The ASI120 can take exposures of up to 1000s according to this page, without extra cables. You will need darks!

I would have a look at deepskystacker (free software) for stacking the images.

DSS is good.  I still prefer RegiStax though.  (Both free)

Registax is for planetary rather than DSO which is what the OP will be imaging.
