Milky Way from High Halden

I agree it's a very good image, especially with only 15 exposures, well focused and good star shapes too from that Nikon glass.

Have you tried the 550D yet, even without cooling the copper should keep the sensor temperature down.

The heatsinked 550D was used on my IC1340 (Veil) image.  The decrease in noise just having the copper exposed to the elements is quite noticeable.  It almost completely stops the heat build up of the sensor.  Haven't added the Peltier yet.

Yes, I noticed how noise free the Veil image was.  Did you see banding in any of the processing steps ?
