Omega wide field

[Peter Ward]

Found some quite old AP data on my hard drive, which was finally salvaged using Russ Croman's gradient exterminator

Reproduced at half resolution.

Beautiful image, Peter. Lovely star colours.

Thanks Mike.

Some details, taken from the 'burbs, AP155, SBIG STL11k, RGB 15:10:15 Mins

Cheers
Peter

Peter, Lovely image for such a lack of data...though its a bright target so you can get away with basic RGB. As Mike points out, you've managed the stellar profiles exceptionally well. Good work.

Thanks Jase

I find stellar objects rarely need megadata. Dim extended objects are another story entirely!

Very impressive. I see youve got ESO220-008 abd a few other fainter galaxies. Good job maintaining the core of Omega centauri too. Can resolve it to the core without signs of overexposure.

Nothing short of what I expect from you!

Stunning..

Thanks guys....appreciated...but I was more pointing to the observation with the right tools i.e. CCD + software, you can get good images from light pollution central

[AlexN]

Which makes me happy, as I live 20kms from brisbane CBD (and am on a hill which only serves to accentuate the problem....

[strongmanmike (Michael)]

Woohoo! Omega she's still around!

Great FOV peter, was that with the AP CCD focal reducer in the train? Looks like the normal FL though..?

Mike

[robgreaves]

Great shot, lovely colours, and tight stars

I never knew that patch of emission nebulosity at 2 o'clock was there either until I saw it in your image.

Regards,
Rob

Humm... To tell you the truth. I don't know which AP scope I used (130F6 or 155 F7) both have field flattners....the data is 2-3 years old and I only decided to process the data to see how Russ' software fared.

But, yes . boring old Omega is still there

I suspect that is just a subtle processing artifact...i.e not real... sadly I couldn't find any flats for that data set... But it is in focus

[Garyh]

Nice clean and crisp! and those little background galaxies really stand out.
No sign of a gradient there!
Nicely done Peter!

[Lester]

Fantastic image.

[Phil]

Great stuff Peter had a close look at it with the sky six you can also see
PGC47092
PGC47003
PGC47340
Good fun trying to spot the little things.

I can help you there, it'd be the 155. I have imaged this with the 140 at F7.5 and yours is slightly larger image scale. The 130 with the STL11 would be a much smaller image scale.

Yet another truly magnificent picture. Stars stars and more stars. The collection of perfect blue ones in this picture give it a surreal appearance.

[Ric]

Stunning Peter, quite stunning indeed.

[Peter Ward]

I'm quite surprised by the positive responses. The AP155 (thanks for the detective work Greg)...in fact AP scopes in general...have quite extraordinary glass. My 155 simply doesn't need refocusing across an RGB filter set.

Big APO refractors are also very forgiving in urban environments.... great contrast and no secondary obstruction shadows to cope with on top of the inevitable LP gradients.

Again, many thanks for the feedback...

As a guy from the northern hemisphere I have to thank you for that wonderful pic. I have never seen this obejct with my naked eyes.
