NGC 2903
Barred Spiral Galaxy in Leo

This image of barred spiral galaxy NGC 2903 was captured by Mike Lancaster on the 17th March 2026. Both close-up and wide-field versions of the same image are shown. The faint dwarf galaxy UGC 5086 lies to the left of NGC 2903 in the 8 o'clock position, and appears as a faint fuzzy patch. The image comprises 120 x 30 second exposures taken using an Altair Hypercam 26C at 300 gain (plus darks, flats and flat darks), through an Orion Optics UK AG12 Astrograph mounted on an EQ8 mount. A 0.95x Wynne Corrector and IDAS LPS-D3 filter were also employed. No guiding was required due to the relatively short exposures. Images were acquired using SharpCap, and the processing was entirely performed in PixInsight. Image Credit: Mike Lancaster.
