My first omega centauri taken with 10"meade SCT @FR6.3 10X10min subs orion starshoot2 no darks or flats
Just noticed a small fuzzy to the mid left of the cluster If someone is in the know maybe they could enlighten me as to what the object is. A fair amount of blue stragglers in this shot which was my reason for interest in this object.
Constructive critism is always welcome as Im a pretty much a newbie I am enjoying the learning curve tho.
Thanx for looking
Thanks yes thats the one I might have a go at imaging this galaxy on its own next at full power and see how it goes. Ive been imaging for about a year now and that equates to about 5 or 6 suitable nights only really. Ive just taken delivery of some bahtinov masks and bobs knobs to help with focusing and collimation so I may be able to refine things a bit using them along with some darks.
I have to admit I got a buzz when I saw this little fuzzy object ( I only noticed it when I enlarged the pic for my desktop) and I think it will add some objectivity to my astronomy endeavours rather than just blasting around the sky taking shots of the bright stuff.
Thanks for the comment I am humbly proud of that shot.

1. Always centre the object before shooting (assuming you want the object centred in the final image) otherwise you will lose some of the field when cropping the final image. So I would suggest cropping this image so the cluster is centred.
2. The background is too black. The sky isn't jet black so when you processed it you cut off part of the low end of the light data to make the background look black but you lost some data doing that as well.
That is called clipping (cutting) the histogram ( a graph of the different brightnesses in an image).
On the other hand you did a lot of things right in this image - focus, tracking, exposure time (the core is resolved).
Thanx Im not much on clusters either the only reason I spent time on this one is I read about blue stragglers and wanted to capture some of those.
I'll take the critical comments on board now that you mention the dark background I;ll reprocess the data with that in mind, strange tho the shots were taken from the back yardin metro Perth which is very light polluted. All the things I did right was just luck hope the luck holds up.
Top image Robbie!
I too took an image, not at the same exposures as yours, 5 x 4min using an ED80 at 800iso and I have just picked out the same galaxy in my image although not as bright...but it's there.
Just curious...you took this image through your LX200 using a f/6.3 focal reducer, were about's in the train is your focal reducer attached?
I haven't had much luck with mine but I think it may be the setup.
but that's an awesome shot
