Where did you get that from? What a lot of codswallop! Compared to "what" Canon body? I bought the D40 BASED on tests from various sources on the 'net that showed comparative photos from the 400D Canon ad the Nikon D40 - and noise was about the same on both at similar settings. Ving can vouch for these tests too - as he has bought two D40's based on them and is very happy, as am I, with the D40. The fact that a D40 will push to ISO3200 - you'd expect a fair amount anyway.
I have had great success with the D40. Amp noise is far lower than a 300/350d Canon from parallel tests I've run at various ISO settings. I've exposed to the 20 minute mark repeatedly, and each time I get hardly any colour. There's a whole thread on my tests here on IIS. The D40 is now KNOWN for its very low noise characteristics. They've done a lot of development from the days of the D70 and D50 - not that these are old by any means either.
All of the following images are 30 second exposures from the D40 at prime focus on a Meade SN10. The reason for this is that I actually forgot my remote bulb release that night. 30 minutes you'll get out of a bulb shot - but I hope that your mount is going to make it worthwhile. For 30 seconds each, even M31 & M32 started to resolve. Tuc47 and the others are all pretty good in my book for such short exposures. Most were taken at ISO800 and up.
Sorry about the rant, but I get very tired of Canon repeatedly being pushed, flippantly and without reservation, to newcomers by default. Not everyone wants a Canon!
