Astrophotography without a star tracker The Orion Nebula

This video is about photographing the Orion Nebula without a star tracker, i have divided the tutorial in 3 parts. In the first part i will show you how to photograph the Orion Nebula using a Dslr, a tripod, a 300mm lens and an intervalometer or laptop. I used Astrophotography prograp Tool (Apt) on my laptop. In the second part i will show you how to select fast the best images, then how to stack and to edit in DeepSkyStacker. And in The last part i will show you how i did edit the image using Adobe Camera Raw and Photoshop CC. #galaxyartmedia #Orionnebula #Astrophotography

Light frames ( your normal photos) The Light Frames are the images that contains the real information: images of galaxies, nebula...
This is what you want to stack.
Using dark and bias frames will help remove Dark Current Noise and Read Noise from your image
The Dark Frames are used to remove the dark signal from the light frames
Dark frames = photos with same settings as light frames taken with your lens cap on the lens or telescope. The dark frames must be created with the exposure time, temperature and ISO speed of the light frames (resp. flat frames).
Since the temperature is important try to shoot dark frames at the end or during your imaging session. photos or not to be a big difference(maybe maxim 4 or 5 degrees celsius maximum difference)
Take a few of them (at least 10 better to take 20 or more). DeepSkyStacker will combine them automatically to create and use a clean master dark or master dark flat.
The Bias/Offset Frames are used to remove the CCD or CMOS chip readout signal from the light frames.
Each CCD or CMOS chip is generating a readout signal which is a signal created by the electronic just by reading the content of the chip.
It's very easy to create bias/offset frames: just take the shortest possible exposure (it may be 1/4000s or 1/8000s depending on your camera) in the dark by covering the lens.
The bias frames must be create with the ISO speed of the light frames. The temperature is not important.
