Hey Malcolm,
That’s looking great!
Maybe a tad noisy though, as always more data would benefit that.
Top stuff, looks really good! 👍

Thanks Andy.As always a battle between finding time to image it and getting enough data. The Ha is where most of the noise is coming from, so really needed some more data, but weather and a slightly recalcitrant laptop put an end to that! I could knock out a bit more in processing but the target ends up looking soft.



Thanks, very kind.



Thank you Rick, very much appreciated.

That's impressive Malcolm. Clearly not the brightest of objects and you've captured a lot of detail.

[Paul Haese]

Nice detail and colour Malcolm.

Nice indeed Malcolm!

I also like the colours and processing - well done Malcolm :thumbsup:

Nice detail Malcom. Some more data would be good to cut some of the noise

Terrific! Great image scale and tight stars. Top shelf. :thumbsup::thumbsup::thumbsup:

Really nice Malcolm. Considering you got it with a 8” SCT and small chip, I always thought it was a bigger object but it fits perfectly in your FOV :thumbsup:
