Antennae

Hi

the sky was bright (the local wharf was being used to load a ship - with about a megawatt of lights blazing), but the seeing was good at around 2 arcsec (yahoo!). Consequently, the dim extended star lanes got a bit lost in shot noise, but the detail available in the core was pretty good. I used the ESO image as a guide for the colour - a bit more saturation than I would normally use, but the ESO image looks OK, so what do I know.

the cropped image is presented scaled x0.5 to make the star lanes more easily visible and in full scale for the core.

grateful for any feedback. Thanks for looking. Regards Ray

Totally gob smacked!!

Awesome Ray!

This is such a tough galaxy to image, just remarkable detail.

Cheers,

Justin.

Very nice, Ray! The level of detail is great, especially the dust lanes in the core.

Far out Ray...geez you're not wrong, some great seeing you had there

Great job and nowhere near too saturated could handle a tad more even

Crazy detail of fine dust lanes in the merging galaxies.

Great image

Makes me jealous. I want a good image of the antenna so I commissioned my photographer (my son Trevor) to do it on the weekend at Wiruna. Saddly it was raining and we did not go. Oh well try again next month.

Hi Ray,
Absolutely fantastic !! I've never seen so much details in an image of the Antennae as I am seeing in your image. I assume you imaged with your GSO Newt 12", am I right ?

One more comment: that is a definitive image !

Thanks for sharing,

Fernando

That is really excellent, some great resolution in the core area. Congratulations on capturing such a great Antennae image.
IMO saturation could certainly be boosted though, but that's of course a matter of individual taste.

I'm working on this one at the moment and it's really an amazing galaxy pair and an interesting background field too. For example, there is a cool looking distant galaxy cluster at the end of the short tidal stream. Only got 14 hours so far though, so it's nowhere near finished for me

Thanks Justin. it was hard to try to balance the signal and noise in the dim bits - I was pleased with the core detail though.

Thanks Rick. lot going on in the core and it doesn't look like other galaxies at all.

OK, will try some more saturation - seeing is everything eh?

Thanks Rod. the JPEG seems to have "enhanced" the noise structure a bit, but otherwise its OK

thanks Barry. I have been wanting to get a view of these things myself and was really pleased to get some good seeing, even though the sky was pretty bright - better than rain though.

Very generous Fernando - thanks. This was taken with a Skywatcher 250f4 Newtonian that I am in the process of settling in - still have some things to do to it, but it is working pretty well.

Thanks Rolf. looking forward to your image - definitely a good megadata candidate. The sky was at least a mag brighter than normal and I haven't yet got enough data to bring out much background stuff, but it was nice to get some good seeing for the core.


Thanks for the comments guys. Have a bit more data from last night ( not high res though) and will try to add it to get the noise down. Regards Ray

Thanks Alistair. Colour was from one night of poor seeing but dark sky, luminance from a night of good seeing with a bright sky. Got some more luminance from a dark but wobbly sky last night, so might be able to add to it. regards Ray
