Imaged over two nights. Widefield view of Barnard 343 which I originally imaged last year
with the TOA-130F. The above result, however, is using the smaller FS-60C scope for a wider
view. I used a technique to add synthetic "Lum" data using the RGB
(bin1x1) frames. Final result is Ha_HaRGB, where Ha was used
as Luminance, with some stars brought in from the RGB channel,
as I describe above. Ha:R (80:20) was used for the Red channel. Sadr (earlier
work) is directly to the left of this area (and out of this field of
