About 6 hours of data, but poor guiding which I suspect may be the reason for elongation of the stars.  I'm not sure yet if I should give up on the mount or try and sort it out.  Always something to learn....

Gosh, no replies to this excellent image. Apart from the elongation it's very good indeed. Good colour, good light background sky with no clipping.

There is a dodgy Photoshop fix for that kind of elongation. 😁 It's very simple:

Make a copy layer. Change the blend mode to Darken.

Go to Filter-Other-Offset and move one layer relative to the other along the line of elongation. In this case it's easy because it's vertical. I went for a 3 vertical pixel offset as shown...

Before:

After:

If the elongation is not parallel with the chip you can rotate the image till it is, follow the procedure then undo the rotation. I should imagine that this will also be possible in other layers-based graphics programs if you don't have Ps.

Again, what a good image.

Totally agree Olly an excellent image 🙂 

As we actually had 2 clear nights for most of UK on Tuesday and Wednesday, probably a fair few images due to appear, will we get any more this January ??

Thanks, I appreciate the comments.  I'll have a go with Affinity, I stopped my photoshop subscription as I didnt think I needed it.

Elongated stars?? Man alive, I dread to think what you would say about the stars in my images!

Regardless, kudos to you mate on an absolutely stunning image.

Great work.

Loadsa detail. Love it.

Maybe just leave it with the nice field of view you have? It hangs nicely.

Thats a beautiful image. What is the duration of subs?

[Jerry Barnes]

Original data was 225 subs of 120 secs each in two sessions, I think I let DSS pick the best 75% of them.  It didn't look any different to Pixinsight stacking all of them (at least not obviously to my eye).  DSS is a lot faster for me.

The framing wasn't quite right which is why I cropped the way I did but the original could grow on me after reading Alacants's comment.
