Barnard's Galaxy ( NGC 6822 ) in the constellation Sagittarius ( final version )

Recommended Posts

Barnard's Galaxy ( NGC 6822 ) in the constellation Sagittarius ( final version - well, at least until I can get more data :) )

Barnard's Galaxy is one of a number of dwarf galaxies relatively near to us in our Local Group of galaxies. Similar in structure to the Small Magellanic Cloud, Barnard's galaxy is thought to be about half the size and around eight times as far away at 1.6 M Light Years. 

Weather permitting I hope to add more subs to help bring the faint detail further out from the sky background.

Details:

Barnard's Galaxy ( NGC 6822 ).
Skywatcher Quattro 10" f4 Newtonian telescope.
Skywatcher AZ Eq6 GT Mount.
Orion 80mm f5 guide scope and auto guider - PHD2.
Baader MPCC Mark 3 Coma Corrector, no filter.
Nikon D5300 (unmodified).
Field of view (deg) ~ 1.35 x 0.90.
ISO400, 14bit NEF, Long Exp. NR on.
40 x 180sec (1/3 before & 2/3 after zenith) 25 Aug 16.

Processed in PixInsight and finished off in Photoshop.

re-processed to increase contrast and brightness of galaxy and a slight increase in overall sharpness.

Very nice shot. I managed to spot this object a few years back from France. Very hard object as it is obscured by dust in our galaxy, and is in a rich star field.  Well done getting such a good image

Thanks Michael, that is very kind of you.

Looks great - especially for such a difficult object. Also, seems like your Orion autoguider is doing a really good job - i'm just getting started with mine so that's encouraging to see.

If you do, please share the final version with us :)

Thanks, much appreciated.  I think I am at my limit though as far as guiding goes.  I turn off guiding in DEC due to too much backlash that I just don't seem to be able to get rid of (with it on I end up getting a PHD DEC graph that looks like a square wave :( ).  In this image, if you look real close, the stars are just a tad out of round, so 3 min exposures without guiding in DEC is about my limit.

Cheers

Mike

      The weather has been so bad I have had the time to finish a video on using astro filters with the Nikon Z bodies and Nikon camera lenses. There is a manual alternative to the FTZ allowing 1.25 inch filters to be fitted between camera and F-mount lenses, and for some lenses and end of lens solution make sense. FAstroTZ is described here:

      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?

      £180
      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

      Skywatcher 80 ED DS-Pro outfit including matched flattener and motor focus. Now only £350
      This kit gives you a great introduction to astronomy and imaging, which is why it's so popular.  You can see details over at FLO but there is:

      Supplied with Tube Rings & Mounting Plate - please note there is a longer black vixen type dovetail fitted, not the fancy new green short one you will see on the FLO site
      SW motor focus and fitting kit - I've never used this, hence it's not fitted (more details over on FLO)
      Dedicated SW 0.85x reducer/flattener (see FLO for more details)
