Galaxy NGC 1232 and possible "jet" now with UK Schmidt comparison to confirm the jet

[strongmanmike (Michael)]

Thanks for looking and commenting you guys Well, I am glad some can (even kinda) see what is really quite clear to me this end ...there are probably a number of things going on here, different monitors in different lighting conditions, different eyes/brains (perception ability is not the same in everyone) and I am sure there are some spurious features mixed in just to confuse the issue. The jet like feature is clear to my eye in the colour version and obvious in the stretched high contrast, so go figure

Greg you are probably right but I have already moved on to the next galaxy (told ya I get bored) ...soooo, I might leave it to someone else who would just love to prove I am indeed an emperor with averted imagination by finding nothing there in a mega data exposure under dark skies

If I take my CDK 17 to my dark site I think I would give this another go.

Further evidence that there are jets coming from this galaxy is this:

Yeah I have that linked to under the deep high contrast image already

...why don't you just move to Bigga permanently?...drive wouldn't be that far each day would it?

That is on the completely opposite side to Mikes image, and compares not a iota to Mikes jet.
Cheers

Yeah but no but yeah but. its still showing there is a galaxy collision in process which could be providing the energy for a jet.

Surely if there was a jet it would have been picked up by this telescope; as it has picked up the merger/ gas so plainly, yet no sign of anything on the side that Mikes proposed jet is on.
I would like Mike to get some professional opinion on this

I only called it a "jet" for the want of a better description...if is is indeed real it would be more like an extension of stars not a relativistic jet that might be seen in X-Rays. However such a merger may still have produced the feature.

All just thoughts

All done in a single nights imaging...also, no darks, no flats and no gradient removal was performed in the processing of this image, I'm in heaven

I could see a faint extension in the colour version and sure enough when stretched it looks awfully like a star jet, similar to those emanating from NGC 1097 only even fainter..?

NGC 1232

Possible Jet

Comparison with Deep UK Schmidt amplified image

Full Frame

Don't know about the "jets", however it is a very good image Mike

Ciao

Surely since its an entirely uncalibrated image that Mike is stretching then it would contain camera noise etc etc that when stretched as hard as it has would reveal artifacts. I can't see the jet in the UK Schmit image either.

Actually darks, flats and flat darks add noise to an image themselves. So there is some advantage in having a quiet chip/camera and well illuminated FOV so that they aren't necessary in the first place. Having said that, flats are able to equalise variations in sensitivity across the chip inherent in the CCD but not usually for small specific features like this I don't think..?
