Hey Dan.
Pretty darn good for only 45 sec shots. The ISO of 1600 helps for those short timed shots. It sounds like you and I have the same camera with the same mod. I've found through testing that my 450 has a lot less noise at 800 ISO but of course you need to shoot a little longer. I like your stars in this shot. Nice and clean. My SCT bloats the stars plus the cabling on the Hyperstar leaves spikes. Here's a link to mine if you're interested.
Keep up the good work.
