What to image in May with the Unistellar eQuinox 2

The last of the galaxies with the first of the summer globulars: Hercules, M3 and M5 are bright, small and forgiving of a bright sky. Darkness is short north of about 50°, so short, bright targets suit the month.

Moon in May 2027: new on 6 May, full on 20 May. Broadband targets (galaxies, clusters) want the week either side of new; emission nebulae behind a dual-band filter tolerate the rest.

51 targets transit near midnight in May. From a suburban sky the eQuinox 2 gets a solid image of 33 of them in under an hour each; 18 need longer, or a darker sky, or several nights. Times below use the recommended filter and 4 s subs.

Solid image with the Unistellar eQuinox 2, sorted by the Bortle 6 figure. Each link opens the full Bortle 1 to 9 table with sub-length and filter comparisons.
