However, there’s almost certainly no reason why you couldn’t take a good image like this using an ImagingSource camera - you’d need to use long exposures on the camera, and take many subs, and make sure you calibrate them using dark frames. The AS camera should be capable of doing this.

For the image above, I used a 60mm Takahashi at f8.3, with 30×2min frames for the luminance. The colour was 6×3min for each colour, binned 2×2. Processed using CCDSoft, Ray Gralak’s Sigma and Photoshop. The AS cameras may need slightly more exposure (and any extra exposure won’t hurt if your mount can track or guide well enough!) due to the smaller pixel size, and higher thermal and (probably) read noise.

The tricky part in processing is controlling the birghtness of the core - do this by using the “curves” function carefully to pull the galaxy out from the background, and also later on using a mask to prevent the core of the galaxy burning out too much whilst pulling the outer arms up in brightness. A bit of local contrast enhancement afterwards helps to pull out the dust lanes towards the core (using Noel Carboni’s Photoshop plugins).

Hope that helps!
