Beginner question

Hello everyone!

I started getting into photography and Astrophotography is what really got me more serious.

I have been owning a Canon T3i for a couple of years, but never really tested it out until recently.

To do Astrophotography, I got myself a Rokinon 16MM f2 and I also own a Sigma 18-200mm F3.5-6.3 DC OS.

The question is this , after taking some nice photos of the milky way last week, I brought everything in Lightroom and found that there was a lot of noise.

After reading it up, it seems that it is the sensor's capabilities that are producing this.

I would like to upgrade my body, but now am wondering what I should go for. I'm considering a a new Canon, but I am wondering what would be the sweet spot. Should I go full frame? Should I upgrade to a T6i?

What would be a good model ?

Here's an example of what I took

Evening Mathieu, new equipment will usually help for astro just because newer is usually a camera that has better or higher limits to what it can produce with similar noise and dynamic range of a previous model. At this point, your sky is still under exposed if you are shooting for the Milky Way. What you could do is shoot at a higher ISO than previously and stack 10 or more images to remove some of the noise from the image. Try at a range of ISOs between 800 - 6400 to see what your camera is producing and how it's dealing with the noise and heat from the sensor. I prefer to push the image with different techniques before buying more kit though better cameras will make those techniques even better when used.

Thanks for the comment. I did get some new gear though, just because I wanted to be a bit more serious about it. I will take the advice for the next session like this!

I forget about the sensor heating up. A good reminder... I've been frustrated with noise issues lately. Couldn't figure out why. But... what a concept... I've moved from the considerably cooler air temperatures of the Oregon High Desert at night... to Upstate New York and humidity central. Hmmmm... practice practice. :)
