Faint!
The BGO robot imaged Thor's Helmet aka NGC 2359 for me. An emission nebula in Canis Major. One of the RASC Finest NGCs. The south wing is bright; the north wing is very faint. SkyTools shows another wing flying off to the east. I can barely see this.
Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.
I wonder if I need to go back and do longer exposures... I also found it included in an O-III filter list in SkyTools. Yeah. I should get more data.
There are problems in the top-right corner of the frame.
Again, this is unfortunate. There's a triple star system, BRT 2664, north-west of the nebula. Tight stars. But with the blurry collimation issue, the three stars merge together.

Tried again on 29 Jan '17. And took O-III data!
