Flats not eliminating all defects?
Singlin replied to BlueAstra's topic in Imaging - Image Processing, Help and Techniques
This might be a stupid question but are you sure that the Flats are recent? -

Here is a combination of 17 subs of 900s in Ha,OIII and SII. I zoomed the image in as my background does not do the rest of the image justice? Camera: Atik 383L Mount: Mesu 200

I have now done a bit more work on this by adding some OIII data and using a RGB image to make a star mask to add to my narrowband data to preserve the star colours. I combined 100% Ha to the Red channel , 100% SII data to the Green channel and 100% OIII data to the Blue channel.

Thanks, yes it is a HSS image. I am in the process of adding some RGB data for the stars and I also now have some OIII. Within a few days I should be able to do an update.

Which eyepieces did you get for your astigmatism Don?
-
That's what I was aiming to do. I also tried to make the stars much smaller as their were too many. The shot was taken with a half moon so some gradient is present when trying to stretch too much.
