NGC5139

#1

Post by scribbly »


Hello,
finally some good skies and my first opportunity to use my TSA120 for imaging during a great weekend observing and imaging at @OzEclipse (Joe's) place.

Please find my latest image of NGC5139 attached. Captured using Televue 0.8x reducer, EOS-RP DSLR, ISO 800, 30x30sec subs stacked in DSS, and processed in Photoshop.

Thanks to Joe for loaning his TV 0.8x flattener/reducer (for 800-1000mm FL refractors). The TSA definitely does not have a flat field, and while I have cropped this image, the stars were to my satisfaction in all corners at full frame.
This reducer, will at least for me, give me an option to the Takahashi model specific flattener (at approximately 1/3 of the cost).

Thanks for looking and I hope that you enjoy.
Phil

@scribbly

Excellent image


Excellent shot Phil, the blue/yellow star colours are nicely retained, not too many saturated images.

Cheers
Joe

That's a fine image Phil.

Zoomed in its dense core really becomes apparent.

Thanks for posting, I can't see that one from UK.

Hi Graeme,

We are very lucky to have three of the most spectacular naked eye globulars between declinations -50 and -70.
1. NGC6752
2. Omega Centauri
3. 47 Tucanae

Beautiful image! The core is well resolved and sharp.
