Canon EOS 650D Noise

[Lostculture]

Hi Guys, 

Im fairly new to photography and need some advise. All my pictures taken from my canon 650D (with any of my lenses 50mm, 55mm, 300mm) I keep on getting grainy (noise) pictures. I only take pictures on RAW mode, and set my ISO to max 400 when i use shooting modes like P, A+. And when I use M mode I set the ISO to 100.  No matter what pic I take in what mode...all my pics are grainy.

Here are the info on this specific picture:

EF50mm f/1.8 ii

5184 x 3456

RAW 

ISO 100 50 mm f /1.8 1/50 sec

And on this picture the noise is hectic on A+ (green box) mode and the ISO sets itself so high, regardless me setting it to max 400 should it use Auto mode

ISO6400 300mm f/5.6 1/125 sec RAW

For astrophotos, get a solid photo tripod (emphasis on being solid for stability ... not on saving weight) and a tracking head such as a Sky Watcher “Star Adventurer” head or an iOptron “Sky Guider Pro” head (both are priced similarly and are in the $300-400 range depending on the accessories.)

This allows you to do long exposure astrophotography of deep sky objects because the head is aligned so that the mount compensates for the rotation of the Earth.  

I’ve done 8 minute exposures with such a setup (I use a Losmandy StarLapse head, but that tracking head is no longer manufactured).  It easily handles good tracking for typical camera lens focal lengths. 

Astrophotography through telescopes gets expensive (quickly) .... typically thousands of dollars.   So the notion that you can do this with a normal camera, decent photo tripod, and a $300-400 tracking head is a good bargain and a way to get into the hobby without having to spend a few thousand dollars.
