[QUOTE="wornish, post: 582366, member: 15434"] The main reason for stacking is to get rid of noise and artefacts so the more shots the better. I am sure a D7000 at 800 ISO won't be an issue. The D750 will have less noise in each shot. Some "rules" are there to be broken, you can certainly go beyond 1.2 secs. You can just about get away with 30secs if you are well focussed on a fixed mount and avoid star trails. Its less obvious at 20 secs but 30 sec is about the max. DSS will actually align the different shots, even shots taken on different nights, its pretty amazing. I wouldn't recommend a barn door mount as it doesn't give you a great deal more leeway. I did use a Skywatcher Star Adventurer as my first equatorial mount fixed on top of my camera tripod and with that I could go up to 2 mins exposure fairly easily. They are not too expensive and they will get you to the next level. That said .... I still would start on a fixed mount and tripod and learn the technique especially the focussing and the post processing. Have a look at using Bahtinov masks to help with the focussing. Told you it costs $'s once you get the bug. [/QUOTE]
