Spiral galaxy group NGC5364 REPRO

[gregbradley]

Mike Sidonio posted an image of this area several months ago. This got me wanting to image the same area.

I did it a while ago and I decided to accumulate more data. This is about 12 hours worth. It was very hard to process so I am happy with the result.

A beautiful spiral galaxy and a nice elliptical galaxy dominate the field.

I did??...:question: must have been another Mike Sidonio :shrug:...there are many of us out there you know :lol:

Love galaxies and when there are more than one in the field it's even better

Not bad Greg, not bad :thumbsup:...still think that CDK needs to be at Bigga..why don't you move it there :question:

Very nice Greg!

Well done :thumbsup:

[gregbradley]

I must be mistaken and thinking of another area you shot. NGC5044 perhaps. Yes the CDK is begging for darker skies. I am tweaking
various aspects of the scope, the mount and the cameras to maximise it.

Greg.



Cheers Rod.

What a beauty Greg :thumbsup:

Awesome image,

Jo

[gregbradley]

Thanks Jo. I am happy I got an image from it as I invested a lot of time into it. I am ugrading my approach, , gear, settings, software and processing routines to get more out of it.

Greg.

[strongmanmike]

Yes, I did do the cluster of galaxies around NGC5044 :)

Incidentally the field of this latest image of yours is almost exactly what my current system provides, is yours a crop?

Mike

[gregbradley]

There's the native widefield with minor cropping and a crop version which is only about 1/2 the image. I have a Trius 694 ordered as I have been very impressed with yours and Rays images with one. The best sensor/camera that's come along for a while.

Humm....I see some faint vertical banding on the right of the frame.

Very tidy image just the same.

Galaxies and long FL's are pretty much strawberries and cream.

Nice one :thumbsup:

Nice group of galaxies expertly done Greg. The only nit picking I would do is that the background looks a bit spotty on my monitor.

Cheers

Nice galaxy group!

[RickS]

A lovely little group of galaxies, Greg!

[Larryp]

Very nice, Greg!

[Paul Haese]

Great field Greg, but you need to do your flats again. There are a few dust donuts visible in the image.

That said , the galaxies are looking very cool, more integration time though I think.

[Ross G]

Great looking galaxy photo Greg.

[gregbradley]

Thanks Peter. I could not believe the number of satellite trails in the subs. Most had several. This spot must be right in a satellite super highway. Plus in the flight path as a few subs had jet trails in them as well. Those vertical lines must be residual bright sattelites. I'll fix em up.

An AO unit would have been handy as I would have liked it sharper than that.



Thanks Steve. I had quite a bit of trouble with flats. I must have lost a set of flats or never took them after the camera was taken off and replaced when I went to my dark site. I'll see if I can reduce that with Photoshop.



Its a great galaxy group. The main spiral is quite small hence not as sharp as I'd like.



Thanks Rick. Its a pretty groupling. I am not sure now where I found out about it. I thought Mike S posted an image of it but I must have found it some other way.



Thanks Larry. Cheers.



Yes some of the flats were poorly done and I paid for that. Man this CDK is sensitive to flats. Annoying really.



Cheers Ross. I like that spiral. Its a classic shape.

Nice image Greg - this declination is where the geosynchronous satellites are, I imaged it last season, and had dozens of trails crossing over, off to the side of the big elliptical, lucky they don't seem to cut across the nice spiral..... :)

[gregbradley]

Thanks Lee. I see. There certainly is a lot of them.

I did a repro (same links) of the image based on the comments and I think it came up nicely.

Greg

[naskies]

Great work, Greg. I like the repro - the noise and tracks that were distracting at first are now nicely controlled.

[gregbradley]

Thanks Dave. Yes the background was tough but it ended up fine. Modern image software is amazing.

Greg.

[SpaceNoob]

Very cool image Greg, love the deep shots being posted on here lately :D

[gregbradley]

Thanks Chris.

Yes this one was a bit of a marathon for me. I am finding there is quite a bit of waste when doing these longer exposures over several nights. Clouds interrupting only one colour, taking the camera off for a trip to the dark site and reattach without fresh flats leading to inaccurate callibration etc etc. I probably was only able to use 75% of the images taken perhaps less.

Greg.

[Shiraz]

impressive image Greg - colour in particular is excellent.

It sure is a good feeling to battle your way through varied data and then, at the very end, realise that you actually do have something of real value. regards ray

[gregbradley]

Thanks Ray. Yes you are right there. It was a struggle and I am thankful to such powerful processing software that we have available. Amazing.

Greg.

[Rex]

Hi Greg, this is a beautiful image. That spiral looks amazing.

[gregbradley]

Thanks Rex. Yes that spiral is a very pretty galaxy. I have another image of another beautiful spiral galaxy but I am still processing it and adding data to it.

Greg.
