Best of AOP - Galaxies

NGC 1530

Located in Camelopardis, this barred spiral galaxy is one of the largest in the northern sky and has a visible mini-spiral core, thought to be comprised of either hot red super-giants or glowing dust. The bar has driven a high fraction (approximately 25%) of the total gas of the galaxy into the center. Two strong, curved shock fronts curl around a nuclear feature in ring or unresolved spiral arms. The narrow dust lanes along the bar are created by shocks in the interstellar gas due to the potential of the bar.

LRGB color production was used to create this image.

The winds exceeded 30 mph during this exposure (shaking the pier), and the seeing was poor. The extra exposure

time for the luminance image was an attempt to make up for these deficits.

The AO-7 unit was used to acquire this image.

Two iterations of L-R deconvolution (sharpening) algorithm using CCDsharp were applied to the luminance image.

Digital Development (DDP) via Maxim/DL was also used in order to display the very dim and very bright details of

the image simultaneously.

Luminance = 220 minutes binned 1x1

Red = 30 minutes binned 2x2

Green = 30 minutes binned 2x2

Blue = 30 minutes binned 2x2
