From memory an OIII might tease it out a little better.

Yes, that's it - IC 5148. Until it saw it at Glen's I had been
looking for that thing for months.
It's amazing that I can now see it from here,
now that I know what it look like.
Funnily enough, it looks like the Helix through the eyepiece,
about the same degree of brightness - not much!!!
The Argo Navis email list sounds good,
I'll check it out. Cheers, Paul.

That is a good point to turn on Auto Adjust and might solve a lot of your
probs. Sorry I forget
these things since it has been a while since I set up mine. Also might be worth
having a look
at turning Refraction on. I have both turned on you can read up on Refraction
on page 143 of
the user manual. Occasionally I'll look at object close to the horizon but not
often and seem
to remember the Refraction feature helped in pointing accuracy
Have you joined Argo Navis email list? if you haven't you should consider
joining.
"Ghost ring thingy in Grus" do you mean the spare tyre? IC 5148.

Thanks Glen and Rob,
I think the relatively high surface brightness of the galaxy cores,
plus the use of the 12mm EP helped make them visible. The fainter
bits were only visible averted. Lots to see in Eri/Fornax.
Transparency must have been good because I saw that
faint ghost ring thingy in Grus. Argo took me right to it,
the UHC filter helped, but is still twice as faint as at Glen's.
There's been some good advice on IIS from Les D, astroron as the
others, as well as Gary. Auto-adjust on is one thing that will help,
plus aligning on 1 star and Jupiter also - guide stars are few
and far between from my location.
Good luck with the wheelbarrow handles,
I've already barked my shins on mine.
Might have to find some fluorescent labels
so I see the damn things in the dark.
Cheers, Paul.

Second that! some interest and challenging objects there Paul. The Argo does
take a little getting used
to but it won't take long before you'll be an expert. I have the boy's this
weekend but I do intend
on having some scope time this weekend if the opportunity arises. I want to at
least try out my
new wheel burrow handles lol
Cheers,CS

Excellent Paul, especially considering the light pollution.

Hi all, the first report for a while. I didn't keep any notes for the first
sweep around with the Argo. This is only a start as I'm
still getting used to the Argo, trying to minimise positional errors. Notes are
a bit scanty, quickly jotted down.The celestial
river is a good hunting ground for galaxies. If the weather gods are kind I
will be back looking for more. Thanks for reading.
NGC 1386 ERIDANUS
RA 03 36 45.42 DEC -35 59 56.7
CLASS Sa, Sy2
SIZE 3.1X1.5
MAG 12.84v 12mm Nagler (125X)
This is a spiral seyfert galaxy, part of the Fornax cluster. I saw a bright
concentrated core but averted vision revealed the
elongated outer regions.
NGC 1269 - NGC 1291 ERIDANUS
RA 03 36 45.22 DEC -36 15 28.2
CLASS SBa(S)
SIZE 89"x67"
MAG 14.2 12mm Nagler
(125X)
Very small, almost stellar core with a suggestion of a oval shaped fainter
outer envelope in averted vision. The bright centre
revealed this one, normally a magnitude this faint would give me problems. When
looking for galaxies I always scan around the FOV,
looking for other objects, but also giving averted vision a chance to pick up
something that direct vision did not reveal. Now you
see it, now you don't! Concentrated cores and ellipticals are easier to spot
than diffuse, face-on spirals. I'm not sure how this
one object had two NGC classifications.
NGC 1389 ERIDANUS
RA 03 37 11.7 DEC -35 44 46
CLASS SB0 (5)
SIZE 2.1X1.4
MAG 11.5 17mm
Nagler (88x)
Another member of the Fornax cluster, a lenticular galaxy, but just looked like
an elliptical. This one was an oval shaped glow with
no discernable core. The fainter outer region visible in averted vision.
NGC 1404 ERIDANUS
RA 03 38 51.7 DEC -35 35 36
CLASS E2
SIZE 2.5X2.3
MAG 11.7 17mm
Nagler (88x)
This elliptical member of the Fornax cluster was in the same wide field as NGC
1389. It appearance was almost circular. Even
illumination.
NGC 1395 ERIDANUS
RA 03 38 29.6 DEC -23
01 40
CLASS E3
SIZE 3.2'X2.5'
MAG 13.2 12mm
Nagler (125X)
Small round galaxy with a tiny bright core, averted vision suggested a faint
round outer region.
I did log some other galaxies during the session but didn't keep any notes.
