That's Perseus Near the middle slightly to the left. with Camelopardalis, Auriga on the right, and Taurus with the Pleiades closer to the top.
DSS is not designed to stack lunar or planetary images, for that you will want to use Registax.
Providing some imaging stats would help. I.e. exposure and how many exposures.
Capturing the image data is the first step in producing and astroimage/astrophoto. Stacking is the second step, and the post processing the image stack is the final step.
Once you have stacked the images with DSS you need to save it to a 16bit Tiff, and then load it into Photoshop or similar image processing software to continue with the post processing to adjust and balance the color and illumination levels and tones, as well as any other processing that might be necessary, i.e. noise reduction, gradient removal etc.
CS5 has the new HDR Pro and Faux HDR which will allow you to load the 32 bit Autosave.tif file produced by DSS. But you will be limited to the adjustments you can make before having to convert it down to 16 bit.
