NGC 253-dw2 Deep Discovery Image

Click on image to see the full story

Well, it isnít every day that you discover something in astronomy, let alone a galaxy!

As part of a professional team lead by Aaron J. Romanowsky and David Martinez-Delgardo, this is my first involvement in a scientific discovery
and my first scientific paper too. The paper was accepted for publication in the Monthly Notices of The Royal Astronomical Society on Monday 21 Dec 2015.

The galaxy, in this case a Dwarf Spheroidal, was first discovered in a deep image I did of NGC 253 using my Orion Optics UK AG12 a 12" F3.8 corrected Newtonian.
This was then subsequently followed up by deep exposures by the CHART 32 team with their 32" F7 corrected Cassegrain telescope at Cerro Tololo and then finally
the Suprime-Cam on the 8m Subaru telescope was used, in sub arc sec seeing, to resolve stars and confirm the discovery and galaxy classification.

So to discover something so faint and so close to such a well researched galaxy like NGC 253 is extra special and the new galaxy is called NGC 253-dw2

The last line of the abstract is very encouraging too: "We also note the continued efficacy of small telescopes for making big discoveries"

See this is what you get when you go deep! Great that you've discovered something new, cool to see you published in a professional journal! Now all you need to do is discover a new PN!

Cheers Larry and Pawel, it's a very cool... smudge :-)

Wonderful find. It's interesting that your discovery may help advance dark matter research. I think the designation should be changed to MSC 1. (Michael Sidonio Catalog 1)

Mike

Congrats for that discovery. That is something every amateur wishes to do ;-) I got notified from Tak Yaho group. Good luck and continue your discoveries!
