Corwin's Notes

===== NGC 6437 is a star cloud in the Milky Way centered about 0.6-0.7 minutes preceding JH's approximate position. There is no nebulosity associated with it; the numerous faint stars in the area gave the impression of nebulosity at the eyepiece during sweeping. Here is JH's description in full: A very decided, tolerably defined semi-nebulous mass in milky way [sic], with abundance of vS sts, forming altogether a telescopic magellanic cloud. It fills about a field, and has branches and sinuses, and is altogether a very remarkable object. The position and size are not well defined on the DSS images, but the cloud appears to be defined by the surrounding and superposed absorption patches. I've tried to take JH's description into account as I look at the field. I suggest caution in adopting any of the positions I give in the table, including JH's own (from a single sweep).

Steve's Notes

===== NGC 6437 18" (8/19/09): at 73x (31mm Nagler) appeared as a very large group or star cloud of over 100 stars, mostly mag 10-13, in a 30'x15' region elongated NW to SE. The mass of stars is just west of mag 7.3 HD 161855 and is fairly well detached in the Milky Way field except on the NW side where a stream of stars extends to the north and the spreads out into another rich star cloud. The brightest star within NGC 6437 is mag 7.6 HD 161561 on the NW side with a faint companion 25" N. The background glow of the Milky Way surrounding the group is bright, patch and overall very striking in the entire 67' field.
