NGC 2633, NGC 2634 and IFN

This is a wide field image of an interesting region in the constellation Camelopardalis with many galaxies and some Integrated Flux nebula (IFN).

The image is a pure RGB combination with almost 48 hours of accumulated exposure.

The first image on the right is a crop of the central part and shows the spiral galaxy NG C2633 at the top and the elliptical galaxy NGC 2634 at the bottom. The image also clearly shows two interesting dust lanes of IFN (in this image, north is up). 

NGC 2633 is the largest in a group of galaxies that carries its name. The average distance between this group and the Milky Way is about 110 million light-years.

The second image is the full widefield view (this image is rotated 90 degrees), covering a field of almost two degrees (at 1.69 “/pixel). This field includes a large number of galaxies.

To facilitate the identification of the galaxies, the third image is an annotated version of the second image.

Looking through all these galaxies, I found a few so interesting that I decided to do a specific processing of them (in this case with drizzle x2, i.e. 0.846”/pixel).

The fourth image on the right is a collage with four crops (in this image, again, north is up).

The first one (top left) shows NG C2633 and below it, the smaller PGC 213530. 

The second crop, to the right of the previous one, shows NGC 2634 and PGC 24760.

In the third crop, lower left, we have IC 520 and above it, PGC 24978.

The last crop shows NGC 2646.
