Is ZWO ASI183MM with Samyang 135mm good combination

[Delta1]

Hi! Is ZWO ASI183MM with Samyang 135mm or a Canon 200mm f2.8 lens a good combination for wide field astrophotography? Or is the ASI1600MM a better option?

For narrowband imaging.

You will certainly get a better pixel scale with the 183m, but also a better FOV with the 1600, so its more about which is more important to you. Both will do narrowband fine with such fast optics.

This might be helpful - it would tend to favour the 200mm + 183 combination over the 135mm + 183 or either lens with the 1600. Having said that I use a Samyang 135mm with an Atik 428ex for NB and I'm very pleased with the results I get despite the fact that I get "significant undersampling".
