Hickson 49

Elevation 800 m, telescope D = 508 mm, F = 2000 mm. Sky 21.72 mag/sw arcsec, seeing 1-2 arcsec. Hickson 49, galaxy group, UMa. A 5.5 mm ocular shows elongation in A and component B readily. D is seen with effort; it is small and amorphous. 3.5 mm reveals elongation in B and a small, round C next to it. Faint star is S of the group, brighter star WSW.

Hickson 39

Elevation 800 m, telescope D = 508 mm, F = 2000 mm. Sky 21.72 mag/sw arcsec, seeing 1-2 arcsec. Hickson 39, galaxy group, Hyd. Ocular 3.5 mm. Component D and an unresolved streak of A-C. On a side of a long triangle of star, brightest to the N. Faint stars E and W also seen. Galaxy next to the star at the triangle vertex to the S not visible.

Hickson 41

Elevation 800 m, telescope D = 508 mm, F = 2000 mm. Sky 21.72 mag/sw arcsec, seeing 1-2 arcsec. Hickson 41, galaxy group, UMa. Components A and B strongly elongated at different angles with a 13 mm ocular. With 5.5 mm, C comes into view as a small amorphous patch. Bright Uranometria star N, less bright star SW, two faint stars NW, similar star E, threshold star inwards from it. D and the MCG galaxy SW of A not seen. [As sketched, the threshold star is in the position of the nearly starlike component D, USNOA2 Vmag 16. An actual star lies more than 1 arcmin - the length of component A - to the W and has Vmag 17.]

Hickson 45

Elevation 800 m, telescope D = 508 mm, F = 2000 mm. Sky 21.72 mag/sw arcsec, seeing 1-2 arcsec. Hickson 45, galaxy group, UMa. Core of components A, D and extensions of A can be glimpsed in a 5.5 mm ocular. Faint star S [interpolated Vm 15.85], B small and amorphous SW of it. Double star at the NW end of the asterism involving A and D is cleanly resolved. [Separation 8.3 arcsec.] C is invisible next to bright star at the S end of the group.
