OK, so i dont understand how they are coming out like this. You are saving them as jpegs but they are very very small.
So heres some things to make sure of;
First, how are you saving your files in
APT - what format, you need to be saving as fits. Then;
1. Make sure that when you stack you are saving the output as a 32 bit fits. If you are saving the stack as a jpeg then you are lost before you start. And that could be explaining a lot of things. Try stacking in
PI (as i suggested above) that will output a 32bit xisf.
2. Do not resize at any point during your processing in
PI. If you save the file, make sure you save it as 32bit xisf
3. look at the bottom RHS of the
PI window, this tells you important information
#1 is the image size in pixels - yours should be around 5496 x 3672. If its not then the image has been compressed at some stage which makes it nearly impossible to process well.
#2 is the bit size - this is 32 bit. If it says 16 or 8 then you are working on a lower bit level than optimum. 16 may be ok, 8 will not.
4. When you have completed your processing you should save the file as an XISF at full size. Then you need to resize to get to a size to post on here. So open Resample in
PI, and chage the percentage to, maybe 50% and apply that to the image.
5. Then save the image as a jpeg from
PI, leave the quality at 80. Then look at the new jpeg file. You want it to be at least 1000 kb (less than 5000 which is the post limit) If its too big, go back to resample and reduce it further. if its too small, step back in
PI and resample at maybe 75%
6. Then you can post it in here at a size we will be able to see more clearly.
