March 17, 2010: Arkaroola in Southern Australia

Mark Johnston

Arkaroola Tue 17Mar2010 Observations from 10:00pm till 3:10am. 21.7 Mag/ArcSec2

Observers: Mark Johnston, solo trip.
Arkaroola Location: 139 20 East, 30 18 South

Conditions better tonight than yesterday but got a late start due to late dinner. Seeing was great and transparency was really good but I am not sure just when to rate transparency as a 5 so leave it as 4 out of 5. My seeing number is also on a scale of 1-5.

VERY busy night with Focus on Eta Car area and nearby object, the tiny yet amazing Homuculus nebula around Eta Car itself, the keyhole dark nebula next to Eta Car star, Galaxies of Dorado, The oddly nammed Dark DooDad (dark nebula in Musca), LMC Revisited key areas, More Southern Sky Astronomical League targets, DeepMap 600 low targets and Caldwell objects.

I started off trying to catch 1365 but it is fairly low so not much better than a good north-sky observation.

10:15pm 7mmNag 220x 5' size. 45dPA with main core at about 160dPA. Arms rotate CCW. Arm out on W side of bar shoots to N CCW and is the more distinct arm. The other arm comes off the E side and rotates CCW out from the bar but is less apparent but shoots quite a ways out from bar. The arm that heads north appears to have a knot on it near it's turning point that bends to the east.

This section is a wide area of fairly bright galaxies with Ngc1566 as the best of the group as a face-on medium sized galaxy.

Arm seems to be out 2' from core off in the NW and W of the object. Off to SE and East I see a dark area 1.5' from core but it gets brighter all along that side as if an arm is there. 1' Core dia. Slight PA of 20dPA on the bar. A field star trails the core just outside of the core glow. I suspect this rotates CCW because I see arm out of N side curling in that direction. Other arm comes out SSW and near the core seems to be CCW. The arm out of the S is the thinner of the arms but is the most obvious as it moves N out from the West of the core.

AGCS 463 cluster. Decided to try for what I may be able to detect in this very dim cluster. Because I was using the 12" all these were only detections and I was unable to detect the 'dumbell' characteristics of IC 2082 although at the time I was not aware it was so 'special' so was not focused on that specific characteristic.

1:44am 35mmPan 44x OIII Filter. Lambda Cen to left of view. A couple small clumps of stars are in the center from right to left orientation. These are the top and the 'high' cross member of a an upper case A with the top pointing to the left [NW]. This is a very tall A [16']. Starting above the high central cross member of the A which points up [1.6' cross-bar of this A] is the start of a very broad nebulous area that forms a large triangle with one tip pointing to the left [NW]. This nebulous triangle has ended before we get to the base of the big A to the right. It is dark above [SE] the base of the A which is vertical in the view for the base. Below the base of the big A there is a big elongated section of nebuloscity with a width about the size of the base of the A [5'] running along what would be the left side of the big A but down at a 45 degree angle [North] for at least half the height of the A [8']. There seems to be more nebulous area even farther off to the right of the base of the A. [I described this in reference to a big letter A with the open base to the right which would be south-east. The description was in terms of my view, never with actual directions but the field of view would be a 90' field size and North would have been 7:30pm sort of area. I insert lengths and dimensions if I mention lengths relative to the characteristics of this big 'A']

1:46am 35mmPan 44x OIII Filter. Completely fills field [+90'] for an absolutely huge and gorgiously complex field. Giant dark V cuts through this entire area where the width of this channel is about 1/5 field [18'] as it stars from the left [NW] and thins down as it approaches the center where it is lighter due to some nebuloscity in that area but the lane is still apparent. Once past Eta Car star the thinner dark channel breaks to mostly down direction [NE] and as it leaves the area fans out to a much broader dark channel. A third dark lane of about 1/4 thickness of the main 'V' is as if it is on a radius from the central bottom of the 'V' and is first only some nebulous area but then as we move up at 45 degrees to the right [South] this dark lane starts up and to the right [South] out to empty into a large dark area where nebuloscity stops. A 4th obvious dark lane starts 1/6 Fov [15'] above the end of the 3rd radius of darkness as if this 4th line of dark channel is also on a radius from the central point of the main V but it does not start getting dark till the other side of a large cluster/nebulous area [Cr228] or about 1/3 FOV [30'] from the central point of the big V. [I mention I am going to describe clusters but get distracted below then get back at 2:20am only to say that all the stars in Eta Car nebula IMHO do not really seem to stand out as distinct clusters but there are some tiny groupings of more dense areas. So since none were really distinct, I did not bother but only stated the stars in general add a wonderful effect of contrast with many different magnitudes all over within the varied intensity of the nebuloscity. Really too impressive to desribe in words.

My best look at the Homunculus nebula was a 3rd attempt as the other nights I discovered I needed extremely careful collimation so I did that tonight just before this observation.

2:05am 5mmNag 305x What is striking at first glance is this area has a distinct yellow-orange sort of color, especially close in to Eta Car itself. Star itself sits within a small dark disk before main brightness starts in. The two lobes look as if a big peanut with the bottom one [more East] being a brighter lobe. The trailing lobe is more difficult to see and may be smaller. The edge of the peanut on the brighter lobe is fairly sharp in cutoff of the light. In the brighter lobe I detect from time to time 1 or maybe 2 different darker spots along the main axis of the peanut but they are only mildly sharp in moments of good seeing. There are two stars on the other side of the dark disk that are tiny points of similar mag that when taken in with the Homunculus Nebula as a whole add a nice touch to this tiny but unusual field. I detect from time to time a small spike comming off perpendicular to the peanut. [This object requires EXTREMELY accurate collimation and this I learned after 2 earlier attempts]

Now the focus is back to individual objects gathered from assorted lists as targets for this trip

Triangular in general in appearance of an EQ triangle due to the Tier1 main member and corners made with other Tier2 stars.

Off to south is brighter section that looks like a headless bird flying ot the East because of 3 sections of this part of the overall area. Wingspan around 12' and body (with no head) is about 8' in size.

Almost forgot to detail keyhole Dark nebula so a quick trip back to Eta Car area then on with individual targets in that area afterwards

2:20am 16mmNag 95x Above EtaCar star [W] there is a broad dark region that thins as it runs runs in parallel [NW] with the real big horizontal dark leg of the V [NW direction of big V]. Then to left of EtaCar [NW] is a nebulous area but on the other side the DarkChnl1 breaks to the north for DarkChnl2 which is fairly thin [Neck of guitar]. This hits a little nebuloscity but continues on N and hits more nebuloscity. Then I describe another dark patch farther along [This I think is body of guitar]. I go on to describe that from EtaCar we drop down [NE] and I note 3 darker areas of nebuloscity separated by lighter areas as we move North but they are not as dark as the main V or the keyhole. [Second time in this area for this night]

Finally leave the Eta Car amazing complex and many surrounding objects to finish off with some objects far away that are now available at this late hour.

[From here I had 9mm lens in and stated sizes in fraction of FOV but then stated minutes in terms of 16mm lens so tape has to be adjusted for sizes. ]

A line of 3 distinct stars shows up which I suspect are forground or perhaps the main cluster stars. One area that only just stands out is about 1/10 field of view [5'] where just above it is the line of 3 stars horizontal [mostly N-S]
