Hi all.
As you may, or may not, be aware, I am working my way through the Herschel 400 list and I am currently wandering around Ursa Major, galaxy country, galaxies are my least favourite objects to observe.  There are a good number of galaxies in Ursa Major that are faint and would be impossible to view from my back garden, therefore, I ventured down to Wicklow, to Glendalough, to be precise.  In about four hours I bagged 11 galaxies.
NGC 2742 and NGC 2768 sit in the same field of view.  2742 is small and elliptical, difficult to observe.  2768 is an elliptical of similar size and showed a typical elliptical face.
NGC 2787.  Averted vision showed a faint halo surrounding a small core.
NGC 3198.  Large and elongated.  The faint nucleus spreads out gradually to the edge of space.
NGC 3184.  A circular galaxy that is very tricky to view.  The core appeared and disappeared with the seeing.  No details seen in the halo.
NGC 3675.  Very elongated galaxy with a bright nucleus.
NGC 3665.  Circular in shape, the outer arms spread out from the core.  No increase in magnification could show any features.
NGC 3619 and NGC 3613.  In the same field of view.  3619 is small and dim, looking like an out of focus star.  3613, slightly elongated and displaying a very faint core.
NGC 3610.  A circular galaxy that appear star like at lower magnifications.  Upping the power shows the nucleus and averted vision the halo.  No details in the halo seen.
NGC 3631.  Averted vision showed a star like nucleus surrounded by a large halo of material.  Higher magnifications showed a slightly darker halo surrounding the core.  Some mottling in the halo.
It was past three o'clock by this point and very cold, there was some frost on the scope.  Time to call it a night.
I am a cowardly creature by nature, but once I got over my initial trepidation of being out there alone, I soon forgot there was no one around.  There were the sounds of animals.  I have a tendency to talk to myself when observing, perhaps I scared them off.
There are so many faint objects on the list that they require a dark site to be seen.
I started the Herschel 400 last March, I have logged 194 objects, just 206 to go.  I still have to tap into Virgo, Coma Berenices and Canes Venatici, that means lots more galaxies, (GROAN).

I regularly talk to myself while observing, Paul.
The Bible encourages us to do so!
Check out the Psalms.

And even those guys did not have telescopes.

What a truly sensational night of observing you had in Glendalough!

I know completely none of these NGC galaxies.
Which one would you say is the most well known?

Clear skies are here again,

Aubrey.

None of them are well known, Aubrey, they are all dim and obscure, if they were not on the Herschel list, I would not observe them.  NGC 3631 was the best of the bunch, a face on spiral.  As I said, I doubt if any of them are visible from an urban sight, unless observing with a large dob.

That's okay, Paul.
Isn't it just marvellous to see this website is buzzing once again with people observing throughout southern Ireland?
My special thanks to you all.

Excellent report Paul. As a matter of interest, the faintest galaxy discovered by the Leviathan telescope at Birr is also in Ursa Major. That's NGC 2689. Various magnitudes are quoted but according to a recent Lord Rosse biography, it's mag 16.4

Well done Paul, I’ve been out there many times on my own also, it won’t be long until you get into Virgo, you’ll get much closer to 300 before you know it, it’s crowded with galaxies !

Hi Paul, 

Sounds like you had a great night (and morning) down in Glendalough. What instrument(s) did you bring with you? 

Very well done - keep going!

Darren.

Hi Keith, where do you observe from?  I went to the upper car park and stayed on the road, observing Ursa Major and it being high in the sky, the trees were not a problem.

Hi Paul, I nowadays just observe from home here in east cavan, it's safer ;-)

I used to observe around isolated lakes nearby, and by the seaside doing astrophotography for many years, at all hours of the early morning when most sane people are tucked up in their beds ;-)

Hi Paul.
There are loads of images on Google on NGC 3631.
It seems reasonably easy to find in Ursa Major.

If you complete the Herschel either in 2020 or 2021, I reckon we could recognise you as Ireland's leading amateur astronomer.
Who else has achieved such a feat?

Sunday night 22nd March promises to be clear again.

Kind regards from Aubrey.

Thanks, Aubrey, Ireland's leading amateur astronomer?  I don't think so, there are so many out there more qualified to hold that title.  I don't think I will have the list finished before 2022 at the earliest, there are single tricky objects to be observed, even two in Pyxis, I had to look up Pyxis, it's a good distance south and may need a site with a good view of the southern horizon, Wexford, Cork or Kerry.
There's no hurry.

Pyxis is a winter constellation, Paul.
It's below Hydra's head right now.
Way too low and difficult for me in my back garden.
But guess what?
There are 2 carbon stars within its boundaries.
YY Pyxidis and UZ Pyxidis.
The latter is quite bright varying between 7 and 7.6.

Maybe in 2021, you and I can hunt these down somewhere with a low southern horizon, We can only live in hope!

Clear skies,

Aubrey.
