Stacking
I have a light pollution filter, should I still use it if I am going to process the images with Nebulb?
Very good question and the answer depends largely on the type of filter you have: If it's a narrow band filter (the ones typically used in deep space astrophotography) then I would opt to keep it, since, those filters work really well because they ...
The computer restarted while Nebulb was working during the night
The computer restarted while Nebulb was working during the night. Most likely it was Windows with one of its automatic updates. Many times if you leave the computer running overnight Windows unilaterally decides that it is a good time to apply some ...
In the case of captures taken over many hours with a star tracker, is it necessary to correct the orientation of the images before stacking so that they are all oriented in the same way?
In principle you don't have to flip any image (and even less if you stack in RAW). Nebulb always performs stacking with all images oriented in the same way. This is something that Nebulb manages internally based on the information of the images and ...
After a certain time the Nebulb stacking is paused
It is very likely that this is related to the power plan that is set in Windows, since, if the high performance plan is not selected Windows can make the computer go to sleep after a certain time without the user has interacted with the keyboard or ...
Is it possible to make panoramas with Nebulb?
It must be assumed that Nebulb is not a software for panorama stitching, so a software specialized in panorama creation will be necessary to assemble the final image. That said, it is true that Nebulb can be used to process the different shots that ...
Can dark frames be used in Nebulb?
Nebulb performs stacking and noise reduction without using dark or bias frames, since they are not really necessary in landscape astrophotography. The reason is that when an equatorial mount (star tracker) is not used, the sky moves slightly for each ...
Is it possible to integrate a human figure into the resulting image?
If you want to use a specific image for the ground (with different lighting and capture parameters or even with a human figure) you can import it into Nebulb as a "Master Image" and then select it as the image for the ground. To import and use a ...
Is it possible to change the base image selected by Nebulb?
The image that Nebulb selects as a base when loading the images is always the one that is temporarily in the center (it cannot be changed). This selection is made by Nebulb to ensure that during the stacking process the displacement of the stars to ...
Does Nebulb work for processing deep space objects?
Nebulb is a software specially designed for landscape astrophotography, taking into account both the type of equipment usually used by night photographers (short/medium focal length lenses and unmodified cameras), as well as the main types of ...
Is it possible to use Nebulb simply to reduce noise?
Yes, no problem at all. Nebulb can also be used for simple image stacking (without alignment of any kind) for which there is a specific "Preset": If you select the "Simple Stacking" preset Nebulb performs a stacking of all images (without any star ...
How many images are needed for stacking?
This depends mainly on the noise level of your camera and the amount of light pollution you need to reduce. As a general rule: Higher noise → More images for stacking. More light pollution → More images for stacking. That said, I have found ...
Unsupported format error when importing a Sony or Nikon RAW file
If you get this error when importing a Sony RAW (ARW) or Nikon RAW (NEF) from any of the new cameras from these manufacturers, it is because the new lossless compression format that both Sony and Nikon have introduced in their latest camera models is ...
Can FITS files be imported?
In the future it will be possible to import this type of files directly into Nebulb, but at the moment Nebulb does not support FITS files. That said, a possible option to use Nebulb with images in FITS format is to convert them to 16-bit TIFF format ...
RAW or 16-bit TIFF?
Here it is much closer than if we compare RAW vs JPEG (where RAW is clearly much better). However, in this case RAW also has a clear advantage over TIFF. The main reason for this is that by directly stacking RAW files Nebulb works in the camera’s ...
¿RAW or JPEG?
Without any doubt, in astrophotography it is always better to work in RAW. The amount of information you will be able to obtain after stacking and light pollution reduction will be much higher than if you do it with JPEG images (which among other ...
Do all images need to have been captured with the same parameters for stacking?
No, but yes. Let me explain. There is no problem in stacking images captured with different parameters in Nebulb, but for noise reduction these different images do not add, but subtract. That is, if you stack many images and some of them have ...
