Notes:

Had to take a week off from imaging NGC 7479 ... the nearly full moon was in such a position that it illuminated the inside of the tube, causing a tremendous 'gradient' on the subs. See the 8" version.

17.5": this is one of few northern barred spirals in which the structure is 
clearly visible. A bright bar is oriented N-S with a bright core and nearly 
stellar nucleus. A mag 13 star is off the N edge 1.4' from center and a fainter 
mag 14 star is 47" SW of center. A thin curving spiral arm attached at the south 
end curves to the west and then north beyond the mag 14 star SW of the core. 
This arm parallels the bar along the west side about 90?. At the Sierra Buttes, 
the spiral arm was held almost continuously with averted vision. Located 3.3' 
NNE of a mag 10 star.

13" (11/5/83): fairly bright, elongated N-S, bright core.  Two faint stars are W 
and N.
