How much exposure is enough for ANDROMEDA?

The testing phase of my new Sigma 300mm f2.8 lens continues, and this time I pointed it at the Andromeda Galaxy! I wanted to see how Andromeda looks with this lens and how the image improves as I add more and more exposure time. For the final result, I compared my newly captured dataset at different integration times: a single exposure, a 15-minute stack, a 1-hour stack, and a 4-hour stack. After that, I also compared this result with my big telescope setup, where I collected over 270 hours of exposure time!
