Ngc7793 - Sidonioéd and with better resolution

[allan gould]

Managed to get my act together after a while sorting out new software and imaged NGC7793. It is an open spiral galaxy and belonging to the Sculptor group, together with NGC 253, NGC 55, NGC 300, as well as NGC247 in Cetus. I've not often seen images of this member and decided to see what I can get even though the moon was almost full.
Scope 127mm Apo with QSI583 LRGB (135:60:60:60min) in 5 min subs. Captured with Sequence Generator Pro, stacked with DSS and processed in PS3.
It could probably do with being imaged at a greater FL which I may do later as there appears to be a good deal of detail present.
Comments welcomed.

Ive now added the higher resolution data as explained in the 16th post.

Oooh... Very cool. Lovely details in there.

Looks like a very nice little galaxy, Allan! Nice capture and I'd love to see it at longer FL.

Cheers,
Rick.

Marc and Rick, thanks for the comments and I've set up with the 10" RC to re-image at a longer focal length. I should be able to use the colour data from last night.

Nice Allan. There are a few background galaxies in there too.

Yeh Nice result Allan even with the moon, lovely fine spiral arm knots too, no point wasting a clear night just because the moon is up

Thanks for that Peter. There are quite a few small background galaxies which may come up better with the 10" rather than using the 127mm refractor.

I say forget the moon.... Just keep on imaging!
Im using more FL tonight and thought I should post a Sidonio on it as I've brought out the colour a little better in readiness of getting more detailed Luminance tonight..

Great image!

Nice shot Allan.

[Martin Pugh]

Prefer the second iteration as I thought the first attempt was a little pale. Great effort there Allan.

Thanks Louie, when is your website going to be up and running again?

Thanks Martin, the colour will go well with the close-up luminosity images I'm doing now.
Heavens, I feel another Sidonio coming on!!!!

fantastic detailed image Allan, maybe a tad noisy or is that just artefacts from shrinking for here?

I think the noise may be my processing but Ive just got 30+ 5min subs with the GSO 10" RC to see if I can smooth things out and get more detail.

[Paul Haese]

Excellent detail Allan. The RC10 should give you some more resolution.

Well here it is Paul. A quick process to see if I could meld the 127mm and GSO 10" RC images together with the colour from one and resolution of the other. Seems to work but Ill do a proper process of the data later. There are a host of very small galaxies in the RC image that I want to bring out a lot better.

That's really nice, Allan. Looking forward to the final version!

Thanks Rick, I'm actually quite amazed at the detail that a modern ccd camera can pull out of heavily light polluted skies and am starting a program of imaging less travelled/imaged galaxies that are accessible from the backyard.

Great image Allan, there seems to be a lot going on in that galaxy. Thanks for the view

That's really nice, Allan!
