Two versions of the Trifid nebula, through a 72ed and 80ed. Pretty chuffed with the results! Although think the wider field shot with the ed72 is a bit less noisy.
But, having said this I shot with the ed72 in a bortle 2/3 sky and with the ed80 from my back yard in Perth, so bortle 5/6
Both shot with a 533MC on a Celestron AVX
120 sec subs x 37 on the ed72
120 sec subs x 45 on the ed80
