Hoag's Object

I think I may have glimpsed the central core of this fascinating object just once this week after a few years, on and off, of trying, and wondered if any IIS members had attempted this elusive DSO type.

Wiki link here at https://en.wikipedia.org/wiki/Hoag's_Object

These galaxies are stunning and not the usual target perhaps. Hoag's object located in Serpens at RA 15 17 14 and Dec +21 35 08 has a core at around 16th magnitude. I attempted with a 12" Dob under pristine sky a few days ago and thought I saw the core.

For those interested, there is a lovely pdf detailing the location and charts for others at http://www.faintfuzzies.com/Files/RingGalaxies%20v4.pdf

I hope this pricks your interest in these beautiful, faint galaxies.
Let me know how you get on and any tips etc..

Stu

That's some fine observing to pick up Hoag's Object in a 12". My research puts it at magnitude 15.2, no wonder it took many attempts to see the galaxy core in your 12".

I have started dipping my toe into ring galaxies and Hoag type objects, and find them a nice challenge.

PGC 19481 in Volans is brighter at magnitude 13.2 and in a tight group of several galaxies ranging from mag 14.3 to 17.5. It has a beautiful ring that was apparent in the 32", though it appeared and disappeared around the galaxies circumference, so still a threshold object in the 32".

Hi Allan.

It required a limiting naked eye magnitude of about 6.5 and near perfect seeing. I have heard tell of someone viewing Hoag's object with a 10"!

As you say, the ring galaxies are fascinating but I think I'll need a bigger mirror to make life easier, perhaps glimpse some of the ring, not just the core. I'd love to hunt some down with a 32" glass!
I'm picking you could see many of the more favourably culminating ones listed in the faintfuzzies.com lists Allan.

Clear skies!

I’m certainly keen to explore the ring galaxies more. The ‘problem’ with the 32” telescope is the vast number of objects it opens up for observing. I already have enough observing projects lined up to last me for about the rest of my life. I do like Alvin Huey’s work though and intend to follow in his footsteps as he has very similiar interests to mine.

Cheers N1!

I'd like to have the "problem" Allan has though

The faintfuzzies site has some great downloads available but I reckon I've got some major catching up to do to reach your sightseeing list mate
