Mark Johnston
This OR will be a posting of my reports for the night of March 13 and 15th where I was given the keys to the Mark Oliphant and Reginald Sprigg observatories that are next to each other and on top a tall hill just north of the Arkaroola Resort in Southern Australia.
I am going to write a lot then present the 2 ORs (separated by double lines) because I want to drop tips for those who follow so they learn from my lessons/mistakes. First off I read MANY ORs from lots of TACos as part of my HUGE number of up-front prep/research and this if nothing else is highly recommended. Make your time at the eyepiece count, it is gold.
Doug Sprigg is the generous and very friendly owner of this resort and encourages astronomy with local southern sky party every year as well as regular star tours to his guests at the resort who sign up for such tours. Many thanks go to Doug who is an expert in local Geology and plantlife but also very much a lover of the South Skies. Location is 139 20 East, 30 18 South The use of his scopes was to prove beyond my expectations and I am grateful he allowed me to use these instruments from such a wonderful site he has by his resort.
My wife and I went from San Francisco to Sidney and then a direct hop to Adelaide. I highly recommend anybody doing this not just accept Orbitz schedules and be very sure to leave 3 hour stopover in Sidney, you may ask me offline why but there are great delays in the stopover. Once in Adelaide we drove up through Clare valley to wine country much like California hill country and stayed at Port Augusta the 1st night. I recommend driving out to Horrocks Pass for your 1st night with binoculars or visual OR a scope if you brought one. It is not entirely level but a site much like Lone Rock with very little traffic but great wide open south sky. I took binoucular OR which is not posted as of yet.
My wife, Maggie, and I went all over the place by day (for a FANTASIC set of day trips) so I had VERY VERY little time to 'regroup' for observations. Instead I spent literally a few months getting ready with tons of detailed lists and charts and telrad patterns and my pc and so on and so fourth. HIGHLY recommend serious prep as your time at the eyepiece is priceless. Also HIGHLY recommend getting real nice very wide full-field sky pictures like from Starry Night Pro and study them like crazy (with and without constillation lines) This allowed 1st time under the south sky to recognize things with comfort (EXCEPT PAV with is a huge and extremely dim suckka and where I had a few difficulties in recognition)
Drove up to Arkaroola well up north that involves 100km of fairly well graded dirt road but I suggest you drive over the road oscillations (due to grater) that happen every once in a while 60-70km/Hr because if you go slow it just gets worse. You will get where you are going much faster AND that is what ALL locals do. Get past the natural frequency of the bumps and your suspension.
This OR covers 13th and 15th because the 14th was a bit of a skunk and I gave up with full blanket of clouds still around 12:30am on the 14th. The 13th started with complete clouds and then opened up to a wonderful sky but only after around 11:30pm. 15th was open the entire night and absolutly amazing but I was a bit dehydrated so quite about 1am (yes that was painful to leave then but the next few days made up for it). Conditions varied from very nice on the 13th (21.6 ish on 13th by 11pm with extreme steady seeing and very good transparency and 6.6+ NELM to fantastic on the 15th (21.74 mag/ArcSec, 6.8NELM, fantastic seeing).
Below are my 2 ORs that are written to date and I have 2 more to go so will post both of those as final post later. Sometimes I used a Celestron 14" SCT with a focal reducer to bring it to f/7. This is on a real nice pier and EQ mount. It has tracking that I only used a little as I was very happy with push-to and it's telrad. I shifted to the BinTel 12" f/5 dob (very very much like Orion 12") and used no Paracor till later nights (left it in room this night as I was going to use 14" but shifted to dob once I saw the dob was very nice. I need to research what mirror was in the BinTel 12" because it was very nice.
When I had no number for objects within the LMC or SMC you will notice I say MysteryObject. I will try to figure out what these are once I find a better LMC/SMC reference. At more than one point in the LMC, WHICH I had spent TONS of time trying to get ready for with detailed pictures, I on tape say things like 'Cripes, there are objects all over the place'. Most are dim, tiny 20-30" clusters but there are tons of nebulous regions with no numbers in MegaStar with DSS and megaStar has a huge number of catalogs. Also many Ngc numbers in the LMC cannot be found with MegaStar and may be labeled with other designations or not labeled at all. Refer to NGC/IC Project and do mini-chart dumps of those to paper before you go for the 'interesting' multi-object packed regions in the LMC.
I did not take down sizes in many cases as this was my 1st real LMC night and I wanted to 'stop and smell the roses' so I am very happy with that approach even though observations were 'minimal' on many of these objects.

Clear all this night but observatory in use till 9:30 Southern sky never seen objects with this night the my first real good but general LMC run. For the LMC objects I did not take super detailed descriptions on the most part but kept to general brief observations because LMC is just frankly a lifetime project so I wanted a broad overview more than clinical detail. On 3-17-2010 a few nights later I went back to focus on a few areas I had felt were nice and had detailed DSS printouts of for a closer look.

Below the chin there are dark round areas below and to right of chin and two dark areas below and to left of the chin. so 3 across. Now to below chin is dark area then to right is another dark circle to the right. Nebulous area below the dark circle below right of chin has bright nebulous lower (E) boundry with dark area farther E and faint nebulous far E boundry to this dark area. The goblin's big ear goes out to the left then turns up, W, before it splits to 2 prongs and the whole ear as tall as the head. Moving north of the ear is a dark channel parallel to the ear then light again. Then above the head is a bit of a hump in nebuloscity with another dark area above the eye to the right and nebuloscity extending up twice the height of the head. There is a separate area of nebuloscity around a fair sized grouping of stars that is distinct and round and as big as the large mouth of the goblin.

I had done a long hike this day and think I may have been a bit dehydrated at this time as well.
