Silver Dollar Galaxy

Hi it's hard to believe you can see detail in another Galaxy 15 million light years away so easily. This is the first image after a major rebuild on the fork mount of the 18' newt, after some teething problems it seems to track ok. Hope you enjoy this, constructive criticism is always welcome.

Incredibly smooth and so much detail!
Aperture rules.

Well done Ken, that's a beauty!

Thanks Robbie, Fred, Marc and Jjjnetie aperture does rule but mounting it is a problem. These were short 4 minute subs, might take some flats and bias and do a Sidonio on it.

Outstanding Ken

One of the best inner core shots I seen! Excellent detail. Has inspired me to take longer exposure times on this!

Ken that is an amazing image of my favorite galaxy.
I prefer to call it Caroline's galaxy because Caroline Herschel found it. She also helped her brother catalogue 2500 DSO.
The distance to her galaxy (the average of 4 recent measurements) is 11.7 million light years. (3.6 Mpc)

Very nice Ken, Your rebuild seems to have worked very well. You have captured some lovely detail with this big scope.
Well done.

Great image Ken, lots of nice details ! But as it turns out, it is only 11.7 million light years away ... The only question I have is about the slight dark halos around the stars (which would be the processing, not the rebuilt mount / scope).

TheDecepticon · #12 14-11-2009, 04:24 PM

It is a fine sight in a scope. Makes you wonder if someone there is looking back at us!!

Thanks guys for looking and setting the distance straight, I used a slight unsharp mask on the Luminance layer but it left rings around the stars. I did a repro on it changing the colour balance slightly.

Ken,

Superb image. That image scale is to die for. I'd like a cross somewhere between the original and reprocess.

Well done, sir.

Regards,
Humayun

Fantastic pic - one day I hope to be able to do something like this.

An 18' Newt

- very cool. You obviously meant 18".

I can't beleive the clarity of the core. Very professional!

Cheers

Excellent image. And the spiral structure is very much in evidence which I find is often not the case in images of this galaxy. Great job

Thanks for your comments Humayan, Doc and Dan, finding a processing routine that gives consistent results is my goal at the moment.

Very Nice work Ken

Yes finding a work flow processing routine that is consitent is good.

did you see todays APOD..?

gives us all something to aim for

Thanks for the view of your image Ken; outstanding.

Hagar (Doug) · #20 22-11-2009, 08:51 AM

I like the Sidonio Ken. You have softened the stars a little. Looks a lot better.
