Abell 31 in Cancer
17.5: this giant planetary was best at 83x using an OIII filter. Fairly faint, easy with averted vision, almost round but edges not sharply defined. Two mag 10 and 11 stars either involved or just off edges, three other mag 10-11 stars nearby form a parallelogram enclosing the planetary with sides 11'x8' oriented N-S and WSW-ENE. Located 30' N of O_195 = 7.5/8.0 at 10".
17.5: at 105x with an OIII filter appears fairly faint, very large, diffuse, slightly darker center (partially annular). This planetary has a mag 7.2 star (
13: faint, very large, slightly elongated ~N-S. There is a bright mag 7.2 star at the SW edge and a faint star at the NW edge. Has a brighter rim at 62x to 79x using an OIII filter. Visible
with direct vision.
13: at 62x with UHC filter; unusually bright mag 11 central star surrounded by a fairly faint, fairly large, round, diffuse halo. Slightly better contrast with UHC filter than OIII.
17.5: faint but easily picked up at 100x without filter as a moderately large, round disc less than 1' diameter. Nicely enhanced with OIII filter and appears moderately bright,
crisp-edged and slightly elongated N-S, 45"x40". Also nice view at 100x with UHC filter. Located 6.7' S of mag 9.4
13: at 79x and OIII filter appears fairly faint, fairly small, round, with an even surface brightness and sharp edges. Faint but visible without filter. Easily takes 166x with a UHC filter.
No central star seen with or without filter.
17.5: large but little-known 3' planetary in Hercules. Picked up 100x using an OIII filter sweeping the field. Once identified it was visible continuously with direct vision as a round,
sharp-edged disc which was slightly brighter on the following edge. The planetary was even faintly visible without a filter and several faint stars were seen to be superimposed.
13: faint, fairly large, round. This planetary can just be held steadily with averted vision using an OIII filter which provides a superior view to the Daystar 300.
17.5: nice view at 100x with OIII filter where it is easily visible continuously with direct vision. The disc is at least 1' in diameter, appears slightly elongated and has crisp edges.
At 220x , faintly visible without filter and quite noticeable are two superimposed mag 13 stars oriented ~N-S with one at the N edge (check) and second star near the center. A very faint
star is also visible near the (SE) edge. Estimate V = 14.0.
13: at 79x and OIII filter; faint, moderately large, almost round, estimate V = 14.2. Can barely hold steadily with direct vision but easier with averted. Located 4' SE of a mag 9.5 star.
Collinear with a wide pair of mag 11.5-12 stars about 3' SE.
