NGC 104 ( 47 Tucanae ) and NGC 121 in constellation Tucana - reprocessed


Recommended Posts

Re-processed to bring out more stars and tweak the colours again ...

 

NGC 104  ( 47 Tucanae ) and NGC 121 - by Mike O'Day ( 500px.com/mikeoday )

NGC 104 ( also known as 47 Tucanae ) alongside the far more distant NGC 121 in the constellation Tucana by Mike O'Day ( https://500px.com/MikeODay )

 

 

NGC 104 - 47 Tucanae, is the second largest Globular Cluster in the sky ( after Omega Centauri ).  Only visible from lower latitudes, it was not recorded by European observers until Nicholas de Lacaille did so whilst visiting South Africa in 1751.  Containing millions of stars and appearing about the size of the full moon, 47 Tucanae is in fact approximately 214 light years in diameter and around 15,000 light years from Earth.

The smaller cluster, NGC 121, appears as a companion to 47 Tucanae but is in fact of similar size, more than ten times farther away at around 200,000 light years and belongs to one of the Milkyway's dwarf galaxies, the Small Magellanic Cloud  .

That's a beautiful globular cluster, and a great shot of it. Well done! :) Wish we could see it up here in the Northern hemisphere!

Thanks guys, much appreciated.

There are still some more stars hidden in the noise that I would like to pull out later in the year when it is next high in the sky.

I have to compliment you. That is one of the best globular cluster pictures I've seen in a long time. I like the way that the core is resolved even with a relatively modest aperture which your using. I bet you have really good seeing which seems evident in the quality of the image. A very well done & lets see some more southern targets I would like to see you target the SMC & LMC.

Thanks guys for your very kind comments, they are much appreciated.

I've not really had much success with LMC/SMC; only the one so far and I'm still not entirely happy with it - I'll keep trying though ...

      Hi All,
      I am currently researching which setup to purchase as my first proper scope (once they are back in stock).
      I thought I had settled on the Skywatcher Explorer 130ps AZ GTi but then I saw the Skywatcher Star Discovery 150i for just a little more money.
      Could anyone please tell me the difference between the 2 OTA's (other than the different aperture size), and also the difference between the 2 mounts?
      I realise that the AZ GTi can be modified to run in EQ mode whereas the Star Discovery can't.
      Can the Star Discovery view all the way to the zenith or does the OTA catch the mount or tripod before it gets there?
       
      Thanks

      I've been trying to image a couple of galaxies per night, one pre and one post flip.  On early Saturday morning at 1:30am I changed over to M82, and acquired 63 x 3 mins subs, OSC, totalling 3 hours and 9 minutes of data. 
      Camera: ZWO 2600MC at -10 deg C, gain 100, offset 50
      Telescope: Skywatcher 250PX (blue tube), 1200mm F4.7
      Mount: Mesu e200
      Guiding: ZWO OAGv2, 290MM, PHD2
      Filters: None
      Software: APT for capture, APP and PS for processing
       
      I havent really had a chance to get much use out of this camera since I bought it in December, and I havent processed many OSC images before.  I've a bit of work to do, but still very happy with the quality of the data for just 3 hours of integration time.  I would like to add some Ha to this, but purposely didnt bother during the recent clear spell, as it was moonless nights and I gathered some broadband data on other targets instead.
       
      CC welcome.

      I was using it on my Celestron Astromaster 130eq. I was able to do some astrophotography with it, 15-20  seconds exposure time.
      Price £27 plus postage
      Payment method: PayPal, family and friends method or commercial and  buyer will pay fee 3% extra

      Recently I acquired the eq3 mount and now I'm looking for Skywatcher Dual Axis or enhanced dual axis Motor Drive for this Mount .
