NGC2259
About this celestial object
A compact NGC target just above the horizon—quiet and demanding.
Such inconspicuous NGC objects stem from the great 19th‑century sky surveys—in the telescope they appear small and low‑contrast.
641 x 10 seconds add up to just over 107 minutes; at 58% humidity and only 2.5° elevation, patient integration was essential.
The 250 mm F/5 wide field helps isolate the delicate target against the brightened horizon.
