Description

NGC 7752-53 was the last Arp galaxy pair I drew during the 2014 summer astro-week at Ágasvár. It was a little disappointment because the interacting pair looks pretty much like M 51 in the photos.

In the telescope both components of Arp 86 are relatively bright. There are two stars superimposed on the main component NGC 7753. Their brightnesses are 14.6m and 15.6m. This galaxy is a beautiful, tightly wound textbook spiral in the photos. I could not detect the spiral structure in the 16" Dobsonian. I could see brighter spots and irregularities which can quite well be match with the photos. And I had a feeling which direction the spiral goes. But I didn't see it. Unforunately the tidal tail / arm connecting the two galaxies remained hidden as well. A few details were visible in the smaller NGC 7752 as well. But to see its irregular spots visible in th photos one probably needs a much bigger telescope and very good seeing.

The SDSS (Sloan Digital Sky Survey) photograph of NGC 7752-53 can be seen to the left made with the 2.5m telescope. I rotated and cropped the photograph so that it can directly be compared to my inverted drawing.
