Deep Sky Stacker Blurring

[iksose7]

Was wondering if this has happened to anybody else? I loaded some images into DSS today and the resulting stack was blurry in about 1/5th of the image, all in the same area. I have had this problem a couple times before and deduced that it was the Flats causing this every single time. When i remove the flats and re-stack, the image comes out fine.

Anybody had a similar experience or know what may be the problem and how to fix it?

Cheers

Hi,

Can u post the original subs, flats, darks, and bias and a copy of the stacked image please? Without these it s impossible to tell what is wrong.

Hi A.G, do you need every single sub?? Because that is ALOT of data to post!

Hi,

Post at least a few of the subs and the stacked one to start, it maybe that a few duff subs have got through and spoilt the end game. As for flats, these must be taken at the smae focus point and orientation while pointg at a diffused light source as you already know, getting good flats is an art in itself but noy that difficult once you got the hang of it.

Cheers A.G, i may try setting the % good of subs to use a bit lower. I will have to stack the data again, will post when done

DSS is capable of some strange effects if you get a parameter wrong. My best example is this a 'stack' of a single light frame and a corresponding flat. In one half of the image it has managed to misalign the colour channels. Strange considering it's just a single sub!

That is a major fail by DSS right there Laserjock

Heres the image - i gave it a few quick stretches in PS so you can see the damage.

Hi, this just happened to me.  Do you know the cause/remedy?  Its fine if i exclude flats from the stack.
