Wow, that is beautiful Trevor.
I never succeed capturing anything under a full moon other than the full moon and an occasional moth.

Over 3000 views but only 1 comment, I don't understand that, is it a good image or just people can't be bothered anymore :)

Good question.

Yours is a very good image, and, yes, it appears that people cannot be bothered commenting. Sad but true.

Regards

Tim

This one of the reasons why I rarely post an image on this forum anymore.
Yours is a lovely detailed image.

If you ever get a chance to do it in SHO it will absolutely shine!

Trev,
Images are always subjective as we all know but as I’ve mentioned before your if your using a OSC with a Dualband filter then obviously one wants to produce a Hubble style palette to expose the wavelength of colour that those gases emitted under all types of skyglow , particularly heavier light polluted locations like your Perth location.
Yes your images are fine and you put a lot of hard work into them but IMO it’s the colour calibration and colour channel processing that results in that dreaded “dark salmon or brownish red” right across the whole image.
I’m sure if you could expose those Ha and Oiii and to a lesser extent Sii signals you “may” get more interest on this forum in relation to comments.

Here’s a tutorial that may help as I don’t use Siril …..,

By the way I’ve been on Astrobin for 2 over years now and have only received 4 or 5 comments over that period , I get mostly “Likes” or “Follows” only. Doesn’t worry me , I get more feedback from family and friends who enjoy the images.

If you can sort out the colour I’m sure it will attract more interest

Folk like “pretty pictures” or at least that’s what I’ve noticed

PS: I’ve noticed your back to OSC imaging ?

Best

Looks good to me!

One thing to consider - some/most of those 3000 views might be drive-by visitors who are not members and can't post comments.

Ok thanks for the feedback - guys just wondering that is all - and Martins suggestion is worth me following up - yes back to OSC sold the ZWO not happy with the quality of images producing - may looks to get a MONO QHY when budget permits :)
