Still waiting on a filter set......but given the clearish (Sydney) weather, this little gem was hard to pass up...

Nice pic Peter

, NGC 5286 is a very under rated Globular Cluster in Centaurus

Thanks! That makes at least two of us

Indeed...though the eyepiece (yes, I still use them from time to time

) with a little aperture it's a delight....

Very nice work.
Must confess I'm not familiar with this object - thanks for the education Peter and Ron.

Another nice one. The bright star next to the cluster makes for an interesting composition. I won't mention colour (again) as I know it's a touchy subject right now.

Colour? Colour? The colour balance is perfect! You guys need to have your eyes tested

Paul Haese · #8 25-02-2010, 10:21 AM

Ah Peter, dare I ask why are the stars elongated across the entire field? Am I looking at the right picture?

Are all you guys looking at the same image I am? Even the large star in the field is elongated.

Just an observation.

Simple...my mount has to be yet to be properly re-polar aligned after an electronics replacement.

Peter,

Very nice glob. The camera is a corker.

Ahh that makes sense Peter. I think I read that some where but it did not quite register that you had an electronics replacement. I think I read that something in the electronics had failed. Thanks for the explanation.

Peter Ward · #12 27-02-2010, 07:57 PM

As a postscript, I find it interesting to note with the same polar misalignment no one noticed any guiding problems on my AP155 M42 image.

At close to 3 metres FL, the grizzly bits become obvious (to some at least).....go figure

TrevorW · #13 27-02-2010, 08:16 PM

Pete some are just way to picky IMO also unless you really expand the image defects are often hard to pick for the untrained eye

Paul Haese · #14 28-02-2010, 05:30 PM

Peter, certainly not as evident to the eye with the 155 as this image. Sorry if I am seen to be picky about things but I note that the level of imaging in the last 5 years has trebled due to serious critique of images. Australians are now as good as many of the top imagers from the US and Britain, that comes from being picky.

Hey, no problemo! I welcome this, as I suspect I was labeled "persona non grata" for not being PC on joining ISS....essentially for not saying "that's nice dear"..... High res deep sky imaging is not a given even with top shelf gear.

Many Oz astro-imagers have now excellent gear and can mix it with the best....which is great the see

TrevorW · #16 28-02-2010, 08:51 PM

Hey Paul I wasn't inferring you were being picky I'd expect good critique from you considering your experience, I was stating in general that unless the viewer was being picky the untrained eye would not pick up these defects. Sorry if I offended

I'm with you I'd rather a straight forward honest opinion on an image than

as Pete stated "that's nice dear"

in fact I'm guilty of often not commenting in earnest for fear of offending

maybe as some sites ask when posting an image we shouid add the foot note

C & C welcome

Paul Haese · #17 28-02-2010, 10:48 PM

Peter I know where you are coming from. It is great to see the wealth of talent developing in Australia now.

Trevor, no problem.

Lovely sampler shot Peter.

65mm filter backorder is long enough to kill a man. Surprised you haven't replaced the filter wheel to slot in the 50mm squares while you wait and guide via an OAG. No brainer with a PIR.
