I am also very new at this (3 months) but I do listen to the experts.
I have been using an old Canon 500D.
Here is my understanding:
For targets like Orion where you have lots of contrast and high signal to noise ratio (SNR) the Canon does just fine.
However when I was imaging a very feint Nebula, where the SNR is very low, noise became a huge issue.
No software processing can fix that.
So to fix that you have to reduce the noise at the source ie: the camera.
I have just ordered one of these:
ZWO ASI 1600MC-C cooled camera.
I have been told that I won't look back...
