Nebulae and Globula Cluster ( NGC 6123, 6126, 6127 and 6129 ) in the constellations Corona Australis and Sagittarius

Nebulae and Globula Cluster ( NGC 6123, 6126, 6127 and 6129 ) in the constellations Corona Australis and Sagittarius - by Mike O'Day ( https://500px.com/mikeoday )

The complex of bright nebula reflects the light from nearby stars and shines out from an area of dense obscuring cloud 400 light years away in the constellation of Corona Australis. Their apparent neighbour in Sagittarius, the globula cluster NGC 6723, is in fact much further away with its light just now reaching us from 28,000 years ago. The bright star in the lower right, Epsilon Coranae Australis, is a yellow-white star twice the size of the Sun and is a relative stone's throw away at 99 light years distance from Earth.

That looks really good! I should try it one day. Mind you a 10" f/4 is a slightly different beast to a Sw80ED :(

Well done!

That is really lovely. Managed to spot these from Tuscany some years back (just a quick visual, no imaging).

From memory these were pretty much directly overhead for me; which is best for me of course given the amount of light pollution I have down lower.

      This has been a bit of a project.  Last year I worked out that my 200mm Canon F2.8 lens and ASI1600 would frame the whole of the Veil complex quite nicely.  I captured Ha and OIII data for the east and west nebulae with a Tak FSQ 106 and added this into the widefield image.  Although the Tak data had to be shrunk down it did add a bit of extra resolution where it was needed.  
      The difficulty for me has been the processing.  I have found it really difficult to tease out the faint wisps of detail and have tried the usual routines of micro contrast adjustments using curves along with Scott Rosen's Screen blend/mask inversion method but the results weren't great owing to the close proximity of faint and bright nebulosity.  I'd heard about the PI process tool for removing stars, Starnet, so loaded this and had a rare foray into PI.  This proved very helpful.  It was a luminence created from Ha and OIII using the 200mm lens with the Tak data mixed in.  Then the starless layer was added in PS with the screen blend mode at 50% opacity.  The nebulosity detail was so well preserved I didn't need a mask.  After blending I reduced the stars a bit more using the starless layer again and darken as the blend at 50%.  I should really unleash some of the stars to add a bit of "punch" but I've wrestled with this data enough for now!  I plan to use it further as I look deeper into the Gorgon that is PixInsight!
      Telescope: Tak 106 for E and W veils.  Canon 200mmL lens
      Camera: ZWO ASI 1600 pro mono cmos, Gain 150, offset 50
      Filters: Baader 7nm OIII and Ha
      E+W Veil 10x30 mins each channel for each nebula.  Whole complex 50x5mins for each channel
      Captured with SGP, calibrated, aligned and combined with PI, processed mainly with PS but PI for Starnet.  Ha mapped to red and OIII to both blue and green

      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.🤔

      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

      Having upgraded from canon 1000D to Nikon D5300  how do users of the 5300 find it for Astro I will be using with APT , and how do you take flats as I can’t use Av mode as there is nothing in tools menu to choose no lens ,  do you use in manual mode  and look at histogram ? .
