Ccd for widefield

[Nova2000]

Hi all 

I was thinking of a ccd camera for my widefield imaging rig.ive checked many ccd camera but don't know what to go for. I'm only doing some research now and won't be buying so soon. 

QHY ccd seem good and are also available from a local dealer. Atik and Moravian are shipped by teleskop express. 

I would like to use the ts70ed with it. And guide it via QHY mini guide scope. Mount =star adventurer so I should get 2-3min subs. 

I had to send back my star adventurer due to  a broken part. 

Its a time till I order again. 

As this won't be a main camera for me so I wanna keep the process down to 1500$.and can add a 100 more for accessories. 

Mono/color is no problem for me cause we have 12 hrs darkness during winter.  8hrs of data should give me good results (am I expecting too much?) 

So an hr in each filter may help or I may only use halpha.
