]]> Astrophotography JAICOA http://www.bautforum.com/astrophotography/96932-ngc210-11-19-09-a.html Ngc 2340 / wbl 133 http://www.bautforum.com/astrophotography/96908-ngc-2340-wbl-133-a.html Thu, 19 Nov 2009 21:12:12 GMT Taking a break from Arp galaxies:

NGC 2340 is the largest and brightest member of the WBL 133 galaxy group located about 275 million light-years away in the constellation of Lynx and not far from the far larger Abell 569. The group contains some 13 members though not all are withing my image. I should have moved 2340 from the center to capture more of them but this was taken automatically as I slept so the scope just obeyed my instructions to center on 2340. As with most groups the members are mostly elliptical and S0 galaxies and thus showing the golden color of old stars due to the lack of new star formation. Apparently these galaxies have so interacted with other members of the group that the dust and gas needed for star formation has been stripped from them leaving them to slowly redden and fade away.

The spherical galaxy to the upper left of NGC 2340 is IC 465 and maybe also NGC 2334. Why the "maybe"? Seems there's lots of problems with the visual observations that created the NGC catalog. This is one of them. Since the catalog is numbered in RA order (at the time of the catalog, precession has changed things somewhat since then when looking at galaxies today on opposite sides of the sky) it should be west of NGC 2340 not east. This is the first hint that something may be wrong. For further information I'll refer you to Dr. Corwin's discussion at the NGC catalog. http://www.ngcicproject.org/dss/dss_n2300.asp Scroll down to NGC 2334 and click on the data button then scroll down that window for the lengthy discussion.

The large elliptical near the right edge nearly directly west of NGC 2340 is NGC 2332. Below it is IC 457 which may or may not be NGC 2330. This problem is included in the lengthy discussion of IC 465/NGC 2334 in the above link.

I've made an annotated image showing member galaxies as well as a few non member ones. If they are a member no distance is given. If a non member the distance in millions of light-years is appended to the name. Some have no red shift data so are noted with a ? for distance.

There are some other ID problems in this image. IC 462 is just a blue star. Could it be the observer saw the nearby galaxy but got the position of the star by mistake? I can't find anything on this one.

Then there's the blue object I've identified as [VCV2001] J071006.8+500245 at almost 2 billion light-years. NED shows many different catalog entries for it. One, the one I used, says it is a quasar, one of the closest known. Another calls it a galaxy (RX J0710.0+5002 ID) as well as an X-ray source. It's shown as an IR source in the 2MASS catalog (2MASSi J0710068+500246). It is also listed in several radio catalogs. It certainly is using most of the spectrum. Due to its strong blue color, typical of "nearby" quasars I chose to go with the quasar designation.

Seems my ISP screwed up my connection. I could send tiny text messages but anything larger would stop mid transmission. They seem to have it fixed. Unfortunately this is not one of Arp's more interesting galaxies from a visual point of view.

Arp 187 is classed under Arp's Galaxies (not classifiable as S or E): Narrow filaments. It is otherwise known as MCG-02-13-040A, a radio galaxy about 550 million light years away.

Arp's image, inverted from mine, shows a faint narrow filament going south east from the galaxy. It is best seen in my image if the image size is reduced. On the other hand I show a large filament to the NW out of the frame of Arp's image. It shows on the DSS plates so is real though only slightly above my noise level. I do need to add time to this one. Arp apparently saw the NW filament as shown by his comment: "Faint filament points to dense nucleus. Possible fainter filament toward compact galaxy to NW." The galaxy is located in the northeast corner of Eridanus not far from Rigel. This is likely a somewhat obscured region due to dust in our galaxy. It's also too far south for good seeing from my location.

This field is rather barren of other galaxies. Nor do I see a certain candidate for interaction with Arp 187. It might be that it is the result of a merger that has already happened. The northern filament passes right by a possible candidate. It's just right of the filament and appears like a slightly distorted star. It is the IR galaxy 2MASX J05045039-1013535. Little information is available for it. One note at NED says; "Interacting with compact galaxy to the northwest? Radio-source. M 05-10, 6 arcmin to the north." Is this the galaxy the note refers to? I don't see it being massive enough to have caused this much disruption if at the same distance. It appears to me more likely it is far beyond it. As to the radio source NED doesn't list it or show any source 6 minutes north of Arp 187.

The obvious galaxy west and a tad south of Arp 187 is 2MASX J05044617-1015169, another IR galaxy with little information available.

The large galaxy near the top right of center is IC 401, an SB(rs)b? and possible LINER galaxy about 150 million light years distant. Far too close to have anything to do with Arp 187. There are a few other IR galaxies in the image but none with much information.

This image shows the Orion Constellation in its natural environment. It’s a widefield vista showing all the major components, including Betelgeuse, Rigel, the belt stars, M42, the Running Man, the Horsehead and the flame, parts of Barnards Loop and a faint display of IC 2118.

It’s only 35 minutes exposure, with no flats calibration, so it’s not as smooth as I’d hoped, but like all of my IISAC2009 images, it’s given me a glimmer of hope and something to aim for next time.

The image was taken at IISAC2009, on the Friday night when my USB hub was playing up and I couldn't control the camera from the laptop. I mounted my Canon 20D and my new 24-105mm L IS f/4.0 lens on top of my ED80 and pointed it at the Orion Constellation.

The exposures were guided through my 80mm refractor and the DMK21AU04, using PHD Guiding. The camera was controlled using the timer remote. The lens was at 47mm f/5.6, and each exposure was 5 minutes. Dark frame subtraction was done in-camera. 7 exposures @ ISO800, 35 minutes total data. No flats.

I'm really pleased with how the 24-105mm lens is performing - it's a definite keeper and will definitely make a return to this part of the sky in the future.

This image of M7 (Ptolemy's Cluster) was taken at IISAC2009, early on the Saturday night before it clouded over. The Milky Way was setting in the West, and I captured 50 minutes of data on this object before it set behind the mountain.

This image is my first real deep space (prime focus) image in some time (since January this year!!), so while it’s not in the league of Louie’s beautiful version of M7 that appeared on APOD last week (congrats Louie!), I’m reasonably happy with the image given the lack of data, no flats calibration and the guiding problems I was having at IISAC2009. It really needs to be much deeper and longer to get the golden star field of the Milky Way.

I recently started a new project called The
Legacy Project. This is the first of many in what may be the waning days of
film astrophotography (I hope not of course) and as one of its few remaining
practitioners will be taking special care in planning, processing and displaying
these images.

Description from my flickr page and link to image:

This image is the results of a 75 minute exposure on Kodak E200 transparency
film.

The Cygnus and Cepheus region rides high in the Summer and Autumn sky in the
heart of the northern Milky Way.

The camera and lens used for the image was a Pentax 67 medium format camera and
165mm f/2.8 lens stopped down to f/4.8. The camera was mounted to an equatorial
mounted telescope which tracked the stars by compensating for the Earth's
rotation.

This one is in the geostationary satellite belt as seen from my latitude. Only by waiting for it to get low in the west could I move the belt's perspective such that it fell below the object. But that put it down in lousy seeing. Also it meant the star colors wouldn't align well as they are displaced by the prism effect of our atmosphere. Blue moved so much during just a 10 minute frame I couldn't get it to align very well so stars have a blue fringe. Another problem of viewing through our atmosphere. A few trails can be seen above the main belt. I tried to reduce them as much as possible but couldn't eliminate them completely. I didn't try with those below Arp 292. The trails squiggle back and forth thanks to our unsteady atmosphere.

Arp 292 is a very strange spiral galaxy. It looks much like M104 seen a bit more edge on except the dust lane is skewed a bit from the plane of the disk carrying the spiral arms. At the SE end it seems to suddenly curve down even more. I don't see this in Arp's image, just a straight tilted dust lane. The difference appears one of color. Arp's rather monochromatic blue image does resemble my blue image quite closely. When red and green are added the shape changes. Compared to M104 it is much redder and the halo much bluer besides the tilted dust lane.

In any case it wasn't the dust lane that interested Arp. He classes this under "Group Character: Wind effects. I'm not sure what he's seeing here. There is a large halo of stars around the main galaxy, again much like M104. Though in this case it appears slightly offset to the southeast. Maybe that's what he is referring to. I've attached my image of M104 reduced to how it would appear if at Arp 292's distance. Notice the similarity. Though its halo is more symmetrical than that of Arp 292.

Arp 292 is also known as IC 575, an SA pec spiral in Sextans. Some sources consider the disk a ring. Considering the viewing angle I'm not sure that's known for sure. It's red shift puts it about 285 million light-years from us. This puts it over 9 times further away than M104.

While Arp classes it under "Group Character" those right around it are of unknown red shift so may not form a group. The galaxy down and right is MCG -01-25-057, no red shift data. The one above it is 2MASX J09543313-0650143 and the one down and to the left is PGC 1027592. No redshift data on either.

Going further away down below Arp 292 in the geostationary satellite mess is IC 0574 also at about the same distance as Arp 292 so we can say they are partners. It is classed as SA0. I find no red shift data on the other galaxies in the image. The spiral to the NE (upper left) of Arp 292 is PGC 028586. The one west and slightly north of Arp 292 with an orange core is 2MASX J09540184-0649353. Directly above 292 at the top of the frame is APMUKS(BJ) B095203.23-062758.2. The fuzzy comet like galaxy just below the geostationary satellite trails to the SW of Arp 292 is PGC 1026068. Many other galaxies are cataloged but non carry any useful, to us, information so I'll stop here.

For those wondering where the RGB satellite trails went, all were in the background which when set to gray then vanished for the most part. A couple can still can still be seen if you look closely. With only 4 sub frames usable I didn't have enough for both good satellite rejection and good a good noise level so settled on a good noise level and left them in without trying to clone them out.

This is the first image where I used the ToUCam in optimized color mode, which disables the sharpening in the camera firmware, allowing for higher quality raw data. Looks like a blue cloud on the terminator below the North Polar Cap. Here is an image of Mars that I took this morning.

Taken from my driveway. Scope is 190 mm Mak Newt, Camera is Rebel Mod. 15 x 400 iso 1600, plus 1x1000sec. Guided with ED80, PHD and a Starshoot 1. Skies were a rare 7 out of ten. Generally we are fogged or clouded out by 10 pm, but they held till the moon rose. I hope to have some fun with this filter this winter. Regards, always welcome comments and clear skies all.
