The Southern Beehive Cluster in Carina ( NGC 2516 ) - reprocessed

Recommended Posts

The Southern Beehive Cluster ( NGC 2516 ) in the constellation Carina
 

re-processed ( improved colour balance, more colour in the smaller stars and lower saturation overall ):

Because of its similarity  M44, NGC 2516, which is only visible from lower latitudes, has become known as the Southern Beehive Cluster.

At a distance of around 1300 light years, NGC 2516 is relatively close to us and resides in the same spiral arm of the Milkyway as we do. Containing around 100 stars, with a number of them in the magnitude 5 to 6 range, NGC 2516 has an apparent magnitude of 3.8 and is visible to the naked eye as a small bright hazy patch at the edge of the Milkyway.

Details:

RA 7h 58.4m, Dec -60 deg 41.9'
Skywatcher Quattro 10" f4 Newtonian telescope
Skywatcher AZ Eq6 GT Mount.
Guiding: Orion Shortube 80 guidescope, Starshoot Autoguider, PHD2, guiding RA only

HI Mike005,

Nice picture, just curious to know how much does the Hutech light pollution filter improve your images and how did you introduce it into the light path?

Hard to say how much as I have not done a direct comparison.  I remember that I found a review on the internet somewhere that compared the performance of a number of filters - sorry but I can't remember where it was.   As for fitting it - I use a coma corrector that has a 2" filter thread on the scope side and I simply screw the filter there.  Having said that, I have stopped using it for the moment because I have been trying to capture more realistic colours and LP filters make that more difficult.

      Celestron C8 XLT + extras and SkyWatcher Star Travel 80 (ST80)
      I have a Celestron C8 with XLT Starbrite coatings. Will include the full length base plate, both visual and imaging backs, scope rings, front 8" end cap and the finder scope with it. No box I'm afraid. Optics are good and clean, focal length is huge - 2300mm from memory. This lot would cost close to £1300 new and one with less spec went for £750 on fleabay recently. Might be interested in a part exchange or will let it go for £450 collection only.
      Also, I have a SkyWatcher Star Traveler 80 - good optics, used as a guide scope - just the scope itself (does not include the barlow in the photo) looking at around £50 for it.
      I have decided to save up for another Equinox or even an Esprit.
      Please excuse some of the colours - I used my astro modded 6D which was in the observatory so the "nice" purple is actually black !!
      Both these are collection only.

      I am going to buy Skywatcher EQ5 Pro Go-To mount. But, unfortunately, I am low on budget.
      So, does someone know where can I buy the cheapest EQ5 pro mount?
      Yesterday there was a low price for it (350 €), but they changed it.
      Thank you for your time!

      I found this setup in internet and make me think, with AZEQ6 GT and 2 scopes, different weights and size, without counterweight in AZ mode! 
      - I can put a MAK100mm 3kg +- and a OO VX10l  12kg +- without counterweight?
       
      Does anyone have this setup mount and already used without counterweight with two telescopes of different weights? Is it really necessary to have a balance using in AZ mode?
      The problem to centralize the object with both scopes is true? With the SW AZEQ6 GT?
      Follow the images
      a TSA-120 with 6.5 kg i think and the other with 22kg i forgot the brand hehe you can help me?

      Selling a nice portable wide telescope with great glass and a great field of view
      I have two telescopes and I'm using the 80ED more currently and so this Telescope just isn't getting used anymore
      It has a longer dovetail (originally from the 80ED) so declination balance can be reached.
      Great performer for the price
      Collection only as P&P is like £40 (Northamptonshire - UK)
      Selling to fund a scope or mount upgrade.🤔
      Selling

      Skywatcher 150/1200 f8 planetary Newtonian.
      Bought this originally intending to set up a planetary rig but circumstances call for sale.
      Will come with eyepieces and a collimation eyepiece. Not used by myself and has seen very little use. Mirrors in good condition
      Collection only
      £50
