Astrophotography Explained: Decoding Signal to Noise Ratio and Number of Sub Frames

I've been making videos about signal to noise ratio. I even have a free app that you can use to estimate it! But what does a good signal to noise ratio look like? The results may surprise you! For those interested, here is the gear I use (or equivalent; Orion has discontinued some of their products, so the equivalent skywatcher products are listed). Most of the links are Amazon Affiliate links. Thanks!

It's simple to use!
