Damn I'd have to do at least 10 hours to even come close to that! oh the joy of high quantum efficiency CCDs... oh the pain, the pain.

For a mini-mag it's still mighty purdy, few straight-line asterims in the top left of the full frame too (small things amusing small minds I think the saying goes).

Edit:

Noticed in your cropped image, 3 o'clock, halfway to the edge is what appears to be an edge on galaxy...but not in the DSS image (see attached).

Caught a live one maybe?
Cheers Justin

Although it is still an ABG (anti blooming gate) camera it is certainly still quite sensitive compared to DSLR's and web Cams etc

The unidentified galaxy looks to be a cosmic ray it would appear..? I have now fixed the rogue high energy skid mark . The issue for me in this image was that I only had two Ha and two Red frames (a slow moving sattelite or near Earth object traversed through three 5 min 1.6deg wide subs!) and this chip picks up cosmic ray hits like Tom Cruise picks up alien babes at a Scientology nightclub. To rid them I median combine my subs, problem is median combining only two subs doesn't get rid of random junk, you need at least three. The result was frame with lots of funny red flicks everywhere. I also added the Ha data to my Lum so the flicks ended up in the Lum too. Sigma reject combine may have worked but I prefer to use median in Astroart..... Anyway, I manually removed (almost) all of them

I wonder what the thing Justin found is - a mini meteor perhaps?

Now you just need to do a repro pinpointing its globular clusters...
Thanks, might be worth a look Rolf, I am sure there are a few?

Nice processing and I know this is a tough object to do justice to due to its low surface brightness.
The new CCD and starfire combo are proving a great setup, bringing in the photons quickly.

Definitely a successful data run bagging what you have.
Guess you really got to go for it when your out at your dark sky site.

Well done Migel!
Be at peace now my son, till the next dark clear nights call

Cheers Rich, yes it was a successful few nights, bagging three images with little issue. No marathons this time but stay tuned

Thanks Trev, something not imaged that often
