Delta One

Presenting what is very possibly the first high-resolution, HaRGB mosaic image showing the entirety of this Ha streak, GMN 41 in Puppis.

Found this while exploring a Galaxy Map Finkbeiner Ha survey & decided to try it back in late December, not realizing that it would become a 10-panel mosaic!
Huge thanks to my buddy Blue for patiently setting up my gear at his property & following through with all the captures despite challenging weather conditions.

Big shoutout to Voyager for its amazing web dashboard and mosaic tool, which was invaluable in planning this image, truly amazing software!

For Star Trek fans, it resembles the Starfleet Delta – duty insignia and communicator badge – hence the “Delta One” moniker.

Photographed in LRGB from my astro-buddy Blue’s dark site in Rural Victoria, Australia using Voyager.

About this Nebula

The brightest star is Aludra, (31 CMa), and the open beautiful cluster to the right is Collinder 140, aka ‘The Tuft in the Tail of the Dog.’
The cluster is large @ 42′ (almost two full moons!).

Almost no other information about this beautiful field is available. Let me know if you find any!
