What is your most difficult observation you've made? It would help to mention your scope's aperture and sky conditions. This year I'd have to say that glimpsing the galaxy between M13 and NGC 6207 was my most difficult. I believe it's IC 1296 if I remember correctly. Also the crab pulsar is right up there. Both times were with my 18 inch under dark Illinois skies.

NGC40 took me about two seasons (probably about 5 or 6 nights of observations. It looks so much like the reflection of dew on the lens. Not really faint, but still a little tough.
The globular clusters in M31 have proven a nice challenge.

NGC 40, 7292 were tough with my 8in. Dob.

I think IC 1296 is a little galaxy in Lyra near the Ring Nebula?

Whoops! Should have said:
with 4.25" refl, 14 years old, 1969 - Ring Nebula (at least most fulfilling find!)
Good seeing! You have an absolutely AWESOME scope there ! ! !

Horsehead nebula in 25x150 binoculars at GreatPlainsStarParty in 2002. Sky was excellant. It took about 1 1/2 hour to view, check charts to confirm accuracy for me and neighbor at the star party.
(I would not have tried, but for a binocular review in Cloudy Nights big binocular section that reported this possible)
Thank you CN for the inspiration,

Yes novbabies I just came back to correct my error. It was IC 4617. Thanks

To date Barnards Galaxy was my toughest challenge. I use a 10" SCT and had tried many times to see this faint extended object. I had to wait until I had a night of uncommon transparency to spy its subtle glow.

Hi Darren,
Those are nice observations with any aperture under Midwest US skies. During the 10+ years I observed with my 10-inch Starfinder, the most challenging observations were probably made at the 2003 All-Arizona Messier Marathon. I didn't marathon that year. Instead, I worked on some galaxy clusters, including NGC 5077 & Co. and the NGC 4281 grouping. The principle members weren't challenging but, when I returned home and checked the observations against Megastar, it turned out a couple of the threshold objects I'd seen were MAC galaxies. These have been catalogued by Larry Mitchell in his Mitchell Annonymous Catalog (MAC). Many do have listings in the more obscure professional catalogs but some, including MAC 1219+0515, appear to have no other designations.
Regards,

I'm still struggling to see M101 and M33 from my light-polluted observing patio. Even my 12-inch f/4.9 Newtonian, with LPR filters and 31mm Nagler, doesn't pick up either. Yet it easily reveals many other galaxies that have been reported difficult.
Any suggestions for the next dark-of-the-moon; at least for M33? M101 is now probably too low these October evenings.

Dar,
M33 may be hopeless in your skies BUT with an OIII filter you should be able to pick out it's best HII region NGC604. I've done it in my light polluted back yard but did not see the galaxy. That should come as some consolation if you don't get the galaxy itself.

I think I am going to be embarassed, but under my light-polluted skies, how about M78. Tricky little reflection nebula in a 10" Dob.
I am still hunting for M1 - one of these days...

OOPS! When I said NGC40, what I really meant was NGC7023, the Iris nebula.

I tried again for NGC 40 tonight and it still eludes me. The direction I'm looking in has a LM of 3.3. What should I do?

I'm using a 6" f/8 newtonian.
I'd say my toughest observation was Barnard 33, followed last week by Hickson 92.
Bill, do you recall trying to discern the faint filaments of a huuuge supernova remnant surrounding Taurus with your 18" Obsession? I don't remember the designation of this object, but it seemed like it was a pretty tough/iffy observation. I was only casually observing with you, so I don't recall your final assessment.

Jeremy, that was Simeis 147, on the "Holy Grail" list of visual observing challenges. Looking through Parker, et al's "An Emission-line Survey of the Milky Way," this ultra-faint supernova remnant is barely visible. So, I'm not ready to include that observation as a definite positive. The brightest portions of Simeis 147 are on my short list for this coming winter. We'll see what happens.

Hi Zack
Imo your best bet is to wait for a night when the Bay is socked in fog. Then take hwy 9 over the Saratoga Pass and park at the roadside pulloff ... I think 2 miles or so W of summit. Skies can be excellent in winter. Good enough to see any M, inc. M74. Jmo and good luck!
I used this method to see 20 degrees of Hyakutake's tail back when.
So far my toughest observation is NGCs 184 and 147 in the same field of my 130mm refractor...
cheers aporigine
