Abell 37

Elevation 800 m, telescope D = 508 mm, F = 2000 mm. Sky 21.80 mag/sq arcsec, seeing 2-3 arcsec. Abell 37, planetary nebula, Vir. Easily seen in a 13-mm ocular with an OIII filter. Round with little concentration and soft edges.

Hickson 35

Elevation 800 m, telescope D = 508 mm, F = 2000 mm. Sky 21.80 mag/sq arcsec, seeing 2-3 arcsec. Hickson 35, galaxy group, Lyn. Visible already in a 26-mm ocular as a N-S streak. Starting to be resolved in 13 mm. In 5.5 mm, component B is the brightest, round. Component A to the N is elongated NW-SE. C to its NW is round. D much fainter, elongated EW. Component E is essentially starlike immediately S of B. [It does not appear on the sketch.] F not seen. An extended triangle of stars is NW of the group.

Abell 22

Elevation 800 m, telescope D = 508 mm, F = 2000 mm. Sky 21.42 mag/sq arcsec, seeing 1 arcsec. Abell 22, planetary nebula in CMi. Ocular 13 mm, OIII filter. The nebula is a puff of light immediately NNW of a faint star.

Hickson 29

Elevation 800 m, telescope D = 508 mm, F = 2000 mm. Sky 21.42 mag/sq arcsec, seeing 1 arcsec, transparency 7/10. Hickson 29, galaxy group, Eri. Ocular 5.5 mm. At culmination. Component A visible immediately NE of a star; small, compact. A similar galaxy [not a Hickson member] is NW of a similar star to the W. Two fainter stars to the SE are just visible [mag 15]. Other [galaxy group] components are not seen.

VV 254

Elevation 800 m, telescope D = 508 mm, F = 2000 mm. Sky 21.42 mag/sq arcsec, seeing 1 arcsec. VV 254, interacting galaxies in Peg (UGC 12914, 12915). The two roughly parallel extended galaxies are immediately visible in a 13 mm ocular. The inclined spiral form of each, with facing arms on the NW ends, is visible best in 8 mm. 5.5 mm brings out the bright nonstellar nucleus of A (the W component).
