NGC 4038 Antennae Galaxies with a smart telescope
NGC 4038 Antennae Galaxies is a galaxy about 5 arcminutes (0.09°) across, magnitude 10.2. It is highest around midnight in March, best placed for the southern hemisphere, and faint and spread out; it really benefits from a dark site and a long total exposure. It is larger than every native frame we track, or too small to fill one, so plan a mosaic or a crop.

Imaging tips
Galaxies shine in broad starlight, so light-pollution filters help little. What helps most is a darker site and a long total exposure: plan on one to three hours of stacking for the faint outer parts. Antennae Galaxies is a target for your darkest nights.
