ah amigo, you funny

I read another web page, some guy thinks he can detect an effect of warping in the arms of 2207 at collision area, can quite see it myself, could be an older Image & new evidence has come to the fore ?
Great Subject and Image Mike
Yes I believe they are separate Bob, the smaller IC 2163 is in the background but close enough that it is expected to merge with NGC 2207 in the future. The extended arm of NGC 2207 that passes in front of IC 2163 does look like a gravitational stretch to me though ...who knows

excellent image Mike - another fascinating group.

interested in your comment on using less-than-best data for noise suppression - I have generally got the impression that by the time I process hard enough to extract detail from data that includes lower res stuff, I end up with just as much noise as I would have by using only the best data, but with less processing - and it often looks more natural. If you don't mind giving away trade secrets (I won't tell anyone), how do you go about getting benefit from lower quality data?

That's a superb shot Mike! Nothing about it I don't like.

BTW, I only look at your croped versions! 100% is a waste of my time.

Cheers
Fred

Interesting dilemma huh?...I know what you are saying Rayzor and don't worry I have thought about the same thing myself, so I guess I basically weigh it up..? I still throw some stuff but probably just not as much as some others probably would, especially those who are fully automated or remote and gather data every clear hour. I can't say I've measured and quantised it as such, just good anecdotal evidence through experience processing for 1000's of hrs over more than a decade now and an eye for where the balance is ..although I don't always get it right, I am only human after all ...I'm probably just jealous of every hour of data and like a hoarder I have issues throwing data unless it is clearly less than optimal..?

Thanks Fred the field of view of the cropped version was bound to please you

Well done Mike. Another top notch image and a real inspiration for letting the data speak for itself and not over doing it.

Great shots of two tiny faint fuzzies. Great catch. Surprised you managed to get anything with the heat. The weather is bs lately hey? Does it cool enough at night where you are. Must be like an oven.

Cheers Lucas, the processing flow using this camera is amazingly simple, not having to worry about calibration or gradients is amazing.

Cheers Marc actually the heat hasn't been a problem really, certainly doesn't affect the camera as I have been able to get to -15C easily each night and the chip is so clean I still don't need darks Even after 40C days, the evenings generally cool down here in Canberra so it has been quite pleasant actually..observatory, thongs, beer and galaxies ahhh sigh....bliss

I understand bettera now, that IC 2163 is traveling straight at NGC from our perspective, I mistakenly thought IC was approaching from the side more or less therefore it was already in a situation of Mixing with it. Thanx for explaining that it is still off in the distance somewhat and having mild effects from there, makes a lot more sense in what you have captured in this pair
Cheers.

Good one Mike. Nice strong colours and tack sharp stars

IMO people who do that are not really being honest with the data.

Cheers Geoff, I used no darks, no flats, no deconvolution and no gradient removal on this image either so what you see is indeed what (the AG12 and SXH694 under average seeing and dark-ish conditions) you get
