imaged HD 350461 (Halifax)

The Burke-Gaffney Observatory imaged the double star HD 350461 for me. Located in Sagitta, aka HDS 2798 and SAO 105182. Centred on Tycho 1606 01248 1.

Luminance only, 4 seconds subexposures, 20 stacked shots. FITS Liberator, GIMP. North is up; east is left.

I first viewed this system in Jul '15 and viewed and imaged many times since. I have not been able to split the A and B stars.

SkyTools shows the angle is 280 degrees or so. The image from BGO shows artefacts but I think I see something along the 346 line. Um. It's probably an artefact. Wishful thinking that I have extracted meaningful data. I will need to carefully examined the colour channel stacks.

TYC 01606-1923 1, north-north-west of HD 350461, appears to be a double star in the photo...

HD 186224 is obvious in this image, at the bottom of the diamond or kite.


The colour channel stacks are no better.
