Thor's Helmet (NGC 2359) in bicolor with mono DSLR

[Luis Campos]

Hi all,

 

This is one target I had in mind some time ago, but it rides very low from my usual location, it hardly clears the neighboor's rooftop and this makes for a very difficult target for me, but still I got some Ha and OIII data in two nights, very low on signal but enough to present a decent image of it

 

NGC 2359 AKA Thor's Helmet (what a cool name) is an emission nebula located in Canis Major aprox. 12.000 light years away and 30 L.Y. in size, it's central star a hot Wolf-Rayet type (WR7) interacting with a nearby molecular cloud is thought to have contributed to teh shape we see today resembling Thor's Helmet.

 

The image is somewhat noisy as is is short on signal, only 6x900 secvs. in OIII and another 7x900 secs in Ha, all captured with my 175mm f/4.6 newt. and mono & TEC cooled Canon 550D with Baader NB filters.

 

This nebula literally "explodes" with a OIII filter so I leave here the bicolor version (with synthetic green channel) and the OIII only data:

Great images and with a DSLR too.

This is probably my favourite DSO.
Something I badly want to image but it always fairly low in the sky for me as well as it does not appear in my back garden so would need to go to other site which is tricky due to poor ground conditions. Need to find another site to image from...

Nice images of a spectacular DSO.
