A very faint but interesting nebulous region in Cygnus. Shot with the TEC140 and AP Quad TCC at F5.1, 8x15min H-a exposure.
There is more interesting stuff all around, so I will visit this area again and try a mosaic of the region. It is all very faint, buried in bright stars that overwhelm the picture. A very narrow H-a filter is needed, perhaps a 3nm, to suppress the stars. In my case I was working with a 5nm filter, which did not reject the stars as much as I wanted, so I had to resort to other measures of star filtering.
