Hey, tonight, I think I'll do some Galaxy-hunting. I want to try and find the Galaxy Cluster near M5 ( Is this hard to view, and will they fit in a 1.14* FOV? ), and I want to try 891 again. How big is NGC 891, and is it bright? Should I wait 'til around 2 Am when it's high? Myabe I'll also take a look into the Cat's Eye, 6891 in Delphinus, and maybe attempt the Bug Nebula again.

NGC 891 is faint, and has a low surface brightness, it is best to see this galaxy when it is very dark, and the sky has high transparency. The magnitude of this galaxy is 10, but it is so spread out, that it appears very ghostly, and difficult unless you are under dark skies. I managed to see this galaxy a couple times, once through my 16", and another time through my 12", and it was not easy, my notes are, faint, low surface brightness, highly elongated 10'X 2' NNE-SSW, mottled, dustlane only suspected at higher magnifications. A 10" will do the job, but you need very dark skies, and high magnification to see any detail in this galaxy...clear skies

NGC-891 is not an easy object, even in a 12-inch unless you have very dark skies. You need a dark, clear and moonless night to bag this one because it's large and it's dust lane makes a dim galaxy even dimmer. A length of 13 arc-minutes makes the light of this 10th magnitude galaxy very dilute indeed. When sky conditions are favorable, I have seen this galaxy a number of times with my 10-inch F/4.5 Dob. As for the galaxy group near M-5, you'll have to look for it as soon as darkness falls, and even then it might be out of range. Several members are bright and the fifth one is very small, faint, and involved in the halo of one of the brighter galaxies. I've had no trouble getting all or most of them in a 1 degree field of view.

Yep, NGC891 is faint. It should be easier to see when high. My observation with the 18" at 195x on a night with good transparency is: Faint, 6' long, hint of dust lane, N-S, star at each end.
The Cat's Eye is a nice bright planetary that can that a lot of magnification on good nights.
I looked at NGC6891 last night. My observation is: 334x, Bright, C-star when looking start at it. Kind of blinks. UHC doesn't help.
good luck

Last weekend with dark west Texas skies and a 30" f/4.5, 891 looked pretty spectacular through my 13E. It still looked nice through the 18" f/4.5 as well with a strong, well defined dark lane. In both cases, though, it almost has a "ghost" appearance with respect to its accompanying field stars. It is an interesting case of where the surface brightness is somewhat low (there are many things far lower in SB), yet you can see a lot of definition in the structure. A comparative view in a 6" AP refractor nearby (at much lower power, I should mention) showed its edge-on appearance, but structural details like the longitudinal dust lane were pretty obscure at best, which is a lesson of where higher magnification can be especially helpful (not to mention aperture).

I stopped counting the number of times I attempted to snag 891. By all data (magnitude, high location, etc), I should be staring right at it, but never had any luck until I went to a dark sky site. Once sighted, the dust lane was very easy to make out, but I'll second Bic's above description of a 'ghostly' feel to it. There are no definite edges to it; it just kind of fades out to nothing. Averted vision helps.

I'll try it from the Yellow Bortle Poconos instead. Tonight, I'm just looking at some old favorites in Saggitarius, and Neptune, Juniper, Uranus, and many differant Nebs, and may attempt the Bug Nebula, but maybe not...

My observing notes recorded that NGC 891 was "very faint, at the borderline of visibility" in my Saturn III Binoculars (39x100mm) - I have very good dark skies here - often as good as 21.40 on a moonless night. I also recorded that in the 15" Dob, the central dust lane was 'very obvious' - again, under good seeing conditions...

Regarding the galaxies west of M5, we are starting to run out of time - as it gets really dark, they are starting to get low. However a 10" should show some or most of them.
A good chart of the area helps a great deal (I use Triatlas "C" from Jose Torres). Out of the 8 shown in the old Skalnate-Pleso I have seen 6 in a 10" - one I missed, one I forgot to look for. The brightest is NGC 5846. None of them are larger than 4 minutes.

I've detected NGC 891 with an 80mm achromat from Cherry Springs State Park. It was a rather easy target for Sue French's 130mm apochromat at Stellafane earlier this month.

The smallest scope I have picked up NGC 891 was my 80mm f/5 "short tube" refractor, but it was quite marginal. At my dark sky site (ZLM 6.5 to 6.8 typically), I have little trouble seeing it show some detail in my Nexstar 9.25" SCT. The dark lane extends down most of the length of the galaxy, although the object remains somewhat dim. However, nothing topped the view I got in a 25 inch Obsession at the Nebraska Star Party, as the darn thing looked about like a dim black and white photograph, with tons of detail all along its length. It seems to look somewhat "fatter" than it does in some images, although I imagine that this is due to the fainter halo which flanks the central disk section of the galaxy. Clear skies to you.

I took a peek at NGC 891 with my 6" refractor under NELM 6.9 skies last Saturday. It was very NICE. The dust lane was obvious.

With my 5-inch under mag. 6 sky using 53X it was ghostly and slender, center lane was there with averted vision.

Hey Jake - The galaxy cluster you are trying for west of M5 will not fit into a 1.1 degree f.o.v. The cluster is about 4 degrees long (NE/SW) and about 21/2 degrees wide. The cluster is to the left and below the star 110 Vir. Keeping the glare of 110 (5th mag.) out of you view is a big help in detecting the brighter of these galaxies.
A few nights ago I tried these EGs with my 10" (between clouds) and was only able to detect the 4 brightest (at 10-11th mag.) only as faint small smudges of haze with my 6-6.5 VLM at the zenith (about 5 at Ser Cauda) so without dark skies, these will be a challenge for you. The other 4 are at 12th mag. I also tried NGC891 in And and only seen it as a faint patch of haze probably because it was about 25 degrees above my NE horizon 1/2 hour after dusk. When it gets higher in the sky with no Moon out, you may just detect it in your sky conditions.
Last night while out observing the Perseids, I was able to see the Lagoon near the 1/2 moon, M11 in Scu, M13, with 10x50 binos and could make out the M.W. from Cygnus down to Aquila naked eye. Not bad for having a 1/2 moon fairly low in the southern sky! Finally a break in my cloudy skies Did you see the Helix at an earlier time? Its a very low surface brightness object due to its size and I'm looking forward to trying for it with binos soon. Latter, Mr Q

When the experienced observers on this forum call it dim, take note. I found it difficult in a C9.25 even at a dark site (blue). Required averted vision at first. It's very big, maybe 1 degree off the top of my head, and very dim.
Forget about it in the city or if the moon is up at all.

I copied a good astro photo oriented to my scope view reversed it to white & black for a real 891 contextual map and I still couldn't see it although the location is easy enough. I didn't realize how faint it really is. M33, M1 and M101 are extroverts compared to the sneaky 891.

As for the galaxies in Virgo west of M5, don't give up on ngc 5746 this time of year. Its an edge on stunner, in a league with 4565 and 891. I've seen it through an 8" under fair skies, but it explodes in a 30" under west Texas darkness like Bic Parker describes.

NGC891 is one of those objects that seems to respond better to darker skies than increased aperture. Here's what it looks like with moderately large aperture under moderately dark skies:

I finally bagged this one last fall,dim but still impressive.I love edge on galaxies,the dust lane pops in and out but it is there.
