Yes - the processing could be changed but you could say that about any image.

Bad guiding can still give round stars but those stars will be bigger so
how can you quantify the guiding?
I have heard stories of people being amazed after using an ASA DDM60 mount
& getting much sharper images than a cheaper mount.

There is also the question of seeing - although at short focal length
it probably wasn't a problem.

Anyway - it's a good effort & I hope to see more.
I just call 'em as I see 'em. I thought most would know I'm not PC.

By scale, I mean galaxies need FL....which the 110 doesn't have a lot of.

OK bad guiding *can* give round stars, but IMHO it almost always manifests itself as eggy/trailed stars.

The WO110 can produce needle like stars....which I'm not seeing here..and as for the Bayer matrix bit....seriously? ....I'm still not seeing 12 micron stars...

But they are round..which is good.

M83 is mainly blue in colour.

As I said, stick with it Mark, work on the focus, colour balance and you'll soon be getting top shelf results..
