Centaurus A

Gee the critics are harsh. Looks wonderful to me. Very detailed.

Looking forward to imaging this with the CDK when it eventually emerges from its crate.

Good job.

Nice catch Martin, I missed that. I modified my processing routine in the past to prevent that sort of thing by doing a star mask before doing final stretch and colour boost. Bit of minor mismatch perhaps from the wind perhaps not that gets amplified by the colour boost.

Fixed it manually now but may go back a couple of steps and do it properly.

Cheers,

Greg.

Ah huh, high winds, that'll do it

As far as the detail/granular that is uh ooh Mike doesn't like decon. I personally like it as it is as its quite detailed, obviously not to your taste but hey, that's not firm ground.

Doesn't have the characteristic decon artefacts actually, looks more like the erosion or minimum filter or something anyway as I said it looks great when not looking too close

Sorry you've lost your first to comment rights for 6 months!

....sorry for being picky just that since it is another image of the most imaged galaxy in the southern sky...such minor issues can make all the difference ...and hey, I did say the colour was bluudy good

Still love me..?

One night was spectacular seeing and 2 nights were windy.

Fair enough. I definitely have used a bit of decon here. No minimum or erosion filter though that I am aware of. I know the effect you are talking about and its close to the edge but I thought I stayed just back from it, at least for my taste anyway.

No worries Mike.

Great detail and colour. Windy conditions like that sure don't help, but the result is terrific anyway

Thanks Markas. The truss helps mostly as only the last bit is in the wind stream. I take the shroud off when its windy and that just leaves a smallish section that holds the secondary. The AP1600 is a very beefy mount probably more heavy duty than a Paramount ME. So that also helps. I must say I was surprised. I did throw out a bunch of subs though.

Thanks very much Al.

Given the indifferent conditions you had Greg, that's a very attractive Centaurus A. I would wind back the saturation a bit though but that's just my preference.

Cheers

Relatively minor points raised by others aside, the overall result is very appealing Greg! Lively colour, good detail. Nice work.

Thanks Steve. The central bar is a bit saturated and could be wound back a bit.
