What is your challenge object for this winter...
      #5503786 - 11/04/12 11:35 AM

Right now, mine is the Cone Nebula. Always wanted to see it, but for one reason or another, it never made it on an observing list.
It will this year!

What's your challenge object for the upcoming winter observing season....

Oh, maybe Gyulbudagian's Nebula (in Cepheus). I haven't see it for a number of years (and it is a variable nebula), so I may have to go back to it with my 14 inch (I first glimpsed it in a 10 inch). I have picked up the Cone a few times before, but other than the challenge of actually seeing it (needs a good narrow-band filter and excellent conditions mostly), it wasn't much of challenge to find. Clear skies to you.

For me there's a number of Palomar globulars and Abell planetary nebulae I have on my observing list. Above all, I'm going to look for the Sculptor Dwarf Galaxy this winter. That one will probably be the most challenging one yet for me given the skies that prevail along the Gulf Coast.

Actually seeing it is the reason I'm calling it a challenge.
There are several other objects that can fall into the challenge object category.

Any more of the Herschel 2500 I can get for starters. All of the upcoming Las Vegas Astronomical Society Observer's Challenge objects, and whatever else comes up. I revisit the Horsehead every year so it's nothing new. The Cone? That would be a good one. Don't remember if I've seen it before.

I can never seem to nail the Witch Head or any part of it either.

If I really thought about it, I could probably come up with quite an expansive list.

The horsehead is easy to find but actually seeing it is harder. An H beta filter does help. I have picked it up twice and whenever I have the opportunity I try for it. It needs to be clear transparent skies for sure! Good luck to you all!

My only view of the Horsehead was with my 4-inch TV-102 refractor from a blue zone in the mountains of western NC. It seems like any light pollution at all kills it here in the southeast. Like so many here my next great challenge would be either the Witch Head or the Cone Nebula. Both are easy to find but very hard to see. Here again I think it has a lot to do with light pollution.

I curious to see if my 16" pumps enough light through various filters to help overcome my local light pollution (red zone). I've also got a realy nice black towel that I wear like a scarf in the winter. When I look through my eyepiece I pull it up over my head like a cowl. It's a big help in blocking out stray light, at least until my eyepiece fogs over.

Technically, the Witch Head IC 2118 is in Eridanus not Orion but it does get its reflective light from Rigel.

I've attempted the Witch Head 2 years in a row without success. I guess it's a better bino object than with a large aperture because the thing is so big. I've tried every filter I have and looked for an edge I could follow, somewhere along the brightest parts of it, but no go. I'll try again this year.

Fred, If I am remembering correctly, the Witch Head is a reflection nebula and no filter really works well on it. I think that a wide field-of-view low power refractor or binoculars will work best from a dark sky site so try without a filter and use low power. You may get lucky from your desert location. I would love to hear about any success you have.

Ladies and gentlemen no more calls we have a winner!!!!

Really I just want to get back at my Herschel 2500 project. It's those low down to the horizon late autumn winter objects I need to get to. It's the sky to the south that's the challenge not the actual object.

I've got 2 more Palomar globulars to observe but spring will do fine for those.

The brighter parts of IC 405 should be doable under a fairly dark sky in a 12 inch if you use an H-Beta filter and at least possible using a narrow-band nebula filter. It isn't much, but the H-Beta at least should give you a fighting chance at seeing it. I can see several of the inner filaments in IC 405 in my 14 inch with the H-Beta (52x), but they are pretty darn dim. On a really dark night in an 8 inch f/5 equipped with the H-Beta, I have occasionally seen the very faint band of nebulosity that is west and extends well south of AE Aur (1.3 degrees in length). Good luck and clear skies to you.

Buddy,

You are right. Filters don't do a thing for the Witch Head. With my 16", the field is way too narrow, that's why I went for just a chunk, an edge at one of the brightest spots but no dice. Too close, too small an area, even at 38X, my field of view just isn't wide enough to grab enough sky. This is a case where smaller may be better like you say.

Well, actually a good broad-band LPR filter has been known to help enhance the Witch Head nebula in rich-field telescopes. It isn't much of a boost, but every little thing can help here. I have seen the Witch Head (barely) in a good pair of 10x50 binoculars under a very dark winter sky, but it wasn't all that prominent. All I could really see was a brightening of the sky background rather than something with detail. It was a tad easier to notice in my 100mm f/6 refractor at 15x with the Lumicon Deep-sky filter than it was in the binoculars, but it still was kind of a marginal object. Clear skies to you.

After about a 5 year hiatus of not doing so much observing due to not having my scope with me, I'm getting started back up again and my challenge for this winter is to revisit the Messier Objects. I figure that will be a good start to get me back into the groove. Bagged 27 on the first night out with the scope last night. Looks like M74 is going to be my short term challenge, no luck with it last night, will probably need a darker site to have a chance.

We spied the witch's head last winter, and it is a unique, faint object. We encountered it in a 30" reflector on a good night in west Texas, and were surprised to also see it through binoculars as well. I would describe it as a streak of brightness, with no form and difficulty defining the edges of it. Einstein's cross is on my to see list.

11/16/12. Mid-Ohio, temp 35 degrees, clear, transparency poor/fair, dew getting heavy.

Tried for Einsteinss cross in the club's 36" last night. We located PGC 69457 without issue. First eyepiece was a 17mm Nagler at 336x - nothing. Next up was a 12mm Nagler at around 500x - nothing. The galaxy was looking better. Next was a 5mm Nagler at 1,143x. Just maybe saw something - a brightening on the southern edge of the galaxy with averted vision - probably 60-70% of the time.

We had the telescope about 20 minutes east of the meridian so this was almost as good as it was going to get for the night. If this object is visible at all in amateur instruments, then transparency has to be just about perfect.

John,

I have seen all four components of the cross at the same time once after many many attempts with my 48" F/4. It was two years ago and what I did was to keep at it till I got a dry transparent night with Sub Arc seeing. I used A ZAO II 6MM eyepiece at 813X. Most people do not realize just how small the core of CGCG 378-15 is. Good luck and keep at it I am sure your night will come around.

Einstein's Cross is located almost dead-center in the lensing galaxy, so you won't see it if you are looking towards the galaxy's edge. The galaxy is a barred spiral with a faint star-like nucleus and it is that nucleus which you should be looking at all the time at as high a power as the seeing will permit. In a 25 inch Obsession at the Nebraska Star Party, we did manage to get about three of the components, but it took great seeing to do this. Much of the time, all we saw was a blobby fuzzy version of the galaxy's star-like nucleus, as the seeing never fully settled down consistently. All the components are somewhat fainter than the central one (the nucleus of the galaxy). Below is a sketch I did of what we saw when the seeing settled down. Clear skies to you.

I'd be doing amazingly well just to see the galaxy, I think. Anyone know a minimum aperture for PGC 69457 in a green zone with typically mediocre seeing? (Loaded question, perhaps.)

12.5" from essentially the conditions you describe except good seeing. I located the galaxy with my 12.5" on the observing pad at the school observatory before going into the dome and giving the Cross a shot with the totally manual eq mounted 25". With the 25" at 635X (5mm T6 Nagler) I had strong suspicions of one component so I put a 10mm eyepiece into a 2,5X Powermate (793X) and was clearly able to detect 2 dots about 75% of the time. With my 20" in early Sept I was able to replicate this feat under better conditions using a 7mm UO HD in the 2.5X Powermate for 688X I think this is totally a seeing dependant object. If you don't have the ability to up the magnification then it won't happen.

Thanks, Bill--I'm currently using a borrowed 12.5, so I'll have to give this a shot. I know I won't pick up the Cross, but seeing the galaxy is still a worthy goal, especially since I've mentioned Einstein's Cross at a club meeting and I'd be able to say I'd seen the "host" galaxy.

Thanks for the comments on Einstein's cross gentlemen. I really appreciate the experienced guidance you offer up to those of us that are new to this hobby.

My buddy and I have the tools to nab this object. The only variables seem to be the transparency and seeing. Sooner or later we'll get this.

I re-read some of your comments and mine about the core of that galaxy. My thought is that, this is what I was catching with averted vision. Neither the seeing nor the transparency was very good that night. Thanks again.

I've seen three of the arcs of Einstein's Cross through a 32" ATM Dob at a very dark site. A few other observers saw all four. The magnification used was around 800x.

I would welcome reports from observers who have seen the G and H stars in the trapezium and what atmospheric conditions they feel are necessary to see them, are they more seeing dependent or transparency dependent (or both.) Thanks. Steven, with regard to the waterfall feature of HH 222, is this something one can realistically have a chance of seeing with large aperture amateur Dob? Are there any filters that would be of value for this target? Thanks!

I've caught the G and H stars in the Trapezium in my 16-inch. Nights were very stable, but can't remember transparency. I think it was the stability above all that was key because magnification was up there. When it's in the 220X to 390X range which is when I saw it, if the atmosphere is not cooperative, it spreads the stars out and blurs everything. Those tiny dots blend into the background nebula and they disappear. That one night I remember, it was stable, super clear and I just spotted them but even then it was tough. The background brightness of the nebula makes it harder. There is no black background for contrast.

How dark were your skies when you picked out G and H? Do you think dark skies are necessary since it is already in bright nebulosity??

I don't remember if darkness was as much an issue as clarity. However, darkness goes hand in hand with that as if there is a lot of junk up there to affect the darkness and scatter light, the clarity won't be there either. A little haze might help for settling down planetary viewing but for seeing something like this, I don't think so. Since I'm not really a planetary guy, I wouldn't swear by that though I've seen some of my best views of the planets when there was a slight haze.

hmmmmm, my challenge is a bit lamer than most Ive read here. Mine is to finish what I started 3 years ago.
I began the Astronomical leagues Messier Club.
I managed to knock off 73 in a year, and at the time was certain it would be done by the following summer.
Well life just seemed to bring this project to a halt.
But to bring this back to the topic, I have 6 items for the winter/early spring groups left. M79 in Lepus , M46-47-93 all in puppis, and M63 and M94 in Cnanes Venatici .Modest goals I admit, but I really hate leaving projects unfinished.

Andy, nothing at all lame about your challenges.
I think for nearly all of us, the challenge is getting time to observe and even more of a challenge to get that really good night!

The Cone Nebula, yes. But there are also a lot of galaxies I need to bag in Ursa Major to finish up the H400. Those aren't really so much of a challenge to see, just to be out there to see them at a dark site when UMa is well positioned and the sky is transparent.

Getting my 1.3" diagonal and 8" primary recoated. Then springtime galaxies look out. Ill have my 6" act to tide me over.

A hypothetical deepsky winter challenge if I were to do one would be high-power observing and sketching of the Eskimo and a color drawing of the trapezium region with associated nebula and dark intrusion.

My last view of M42 was a couple weeks ago through my 10" Dob at a dark site. My Baader Zoom allowed me to dial in various levels of magnification, exit pupil and perceived contrast to pull in and emphasize different structures and aspects of the nebula, Trapezium, Fish's Mouth, and Wings.

For the life of me, I do not understand why more observers don't use a good Zoom eyepiece for deep sky. I - or they? - just don't get it.

From a dark sky site: The Horsehead with a 10" dob and Lumicon UHC, the Witch Head with the 10" dob.

From my my local area: Sirius B, and Ngc 2359 - Thor's Helmet.

Never really made a real assault on any of these before.

NGC-2359 - Thor's Helmet responds really well to an OIII filter. I first saw this with my 8" dob years ago. Saw it again later in our club's 31" - magnificent object. You'll like this one.

Stefan's Quintet. I've seen this before a few times, and under dark/transparent enough skies it's readily do-able in my 12". The real challenge around here is being able to travel to a dark-enough site on a good-enough night of transparency uncompromised by too-much humidity. But as with the quest for the Horsehead (which I've also bagged several times in my 12"), you don't always know for sure if the night is good enough until you put in 15-30 minutes trying. In general, travel to a dark-enough site around here means being fortunate enough to have both weather and situational opportunity on a new-moon weekend night, of which there aren't really all that many in a calendar year.

Same for me, to finish the Messier objects as I only seriously started observing in March of this year.

The Cone Nebula is a true challenge object. It's far more difficult than B33.

The only time that I've been able to catch a glimpse of it was through a 30" Tectron Dob at New Mexico Skies (magnitude 7 skies at an altitude of 7,000 feet).

I have seen the Cone a couple of times in my 10 inch Newtonian with a narrow-band nebula filter, but that was on a few exceptional nights. Like the Horsehead, its visibility is highly dependent on conditions. I did see it without a filter in my 14 inch f/4.6 Newtonian one night last winter, but it was very vague and the filtered view was a bit better. This is one object where the H-beta filter proved useful, although it was still a little easier in my DGM Optics NPB filter. Clear skies to you.

Fornax Dwarf Galaxy, plus a few of the Fornax globulars besides NGC1094.

Sirius B star.

Trapezium G and H stars.

Ongoing challenges to try again: Cave Nebula, Palomar 13.
