If you want instant, and I mean instant gratification in colour on a monitor or LCD screen for viewing then the Mallincam is the only way to go. I know its pricey but its loaded with many features. The new g-star looks good as well but can only go to about 5 second intergrations so for live veiwing with the colour chip it will probally be similar to my Mallincam in 7 second mode or less, this will show you a couple of the brighter M objects OK but will probally be all, you really need to get upto at least 14 seconds upto 56 seconds to get loads more and having a 40 below cooled chip also decreases the noise and improves sensitivity by about 2-3 time over the uncooled system.
For imaging, stacking,darks and RGB filter shots then the G-star mono is the go because of improved sensitivity, but what you are saying is that you want to sit back and view alot of things "live" and in colour then you will have to look at the cooled, extended intergration Mallincam series such as the current hyperplus camera, or even better the new VVS Mallincam thats just been released.
I hope the G-star colour can produce some excellent colour live images as at its price its very attractive to most people and I will be keen to see one work as I have a few friends that would love to get one for casual viewing.
My mate, broke his somehow and Rock Mallin with no worries has sent him out a new one even though its 1 year out of warranty and he is still yet to send the brocken one back, so for back up service, first class

.
I am not going to get into who's is bigger than who's as all these cameras are good for what they do in their price range.
If there was a dealer here for them then I would have bought mine here, but I have already spent loads with the local guys so wanted to see all the M objects in colour and many brighter galaxies.
The new g-star looks promising on brighter objects and probally be good but if you go into whats done to the Mallincams then you will see why they are that price.
If you go the Mallincam way then they can be upgraded as new developments come along, for instance mine is one of the first of the hyperplus cooled versions to come out and Rock has just released a new VVS version which comes with a class 0 chip which has less than 2 hot pixels, improved gain, variable intergrations upto 2 minutes if your mount can do it, improved cooling system.
I am sending mine back to him after chrissy for this upgrade to be done.
