21 May 09
Off to a slow start with passing cloud making imaging almost impossible cleared at about 3am till dawn
22 May 09
Just getting one hours worth of normalising data

C14 Dew Sheild

Finally got the dew sheild installed today. It looks fantastic, bright yellow! It is made from three 4mm thick MDF rings 398mm ID and 450mm OD then skinned in a 2mm balsawood sheet outside. The sheet was made with ten 100x600mm sheets glued side by side to form a massive sheet. The outside coating is Solarfilm made for model aircraft, it is easy to apply and a nice shiney finish. Inside is matt black paint. Yet to get clear skies to test it out but it looks real black looking down the barrel.

12 May 2009
Lots of passing cloud and rain, needed to use 120 sec because of close moon and close to peak at mag 11. Got several good runs through the night.
13 May 2009
Just five normalising images taken as MB204 was doing an exit crossing so was more important
14 May 2009
Finally some clear skies without rain. Did about one hour normalising data at two minutes to keep it standard.

Optec TCS focuser installed

Installed last night with no issues. ASCOM driver downloaded and MaximDL is happy. Autofocus routine in MaximDL seems OK time will tell. Temperature compensation will be a big help once we get a co-efficient worked out. Many thanks to Ohio State University Astronomy Dept, who have provided this unit to us for help with microlensing events.

May 04 2009
Lots of passing cloud and rain.
May 13 2009
Again a poor night but managed to catch a caustic crossing exit that will help nail this one down, only 16 five minute images through the night.

Painting

Finally after years of talking about it I painted the dome last weekend over a few days. It had two coats of white Wattle Solarguard. There were a few places that I did repairs on the fibreglass first with west system epoxy resin and glass cloth. The top of the hatch is rotting and needs repair still. Also a coat of Forestwood stain was put on two sides of the Wasp Observatory

Moa 2009-BLG-048

Day 1: UTC 23-03-09 1430 to 1745 hrs
This is the first target for the year. Easy and bright, perfect evening clear, good seeing.

Day 2: UTC 24-03-09 1300 to 1730 hrs
Another good run till dawn. Perfect skies one break due to a computer issue so autoguiding on different star at about image 10?

Day 3: UTC 25-03-09 1200 to 1300
Just a few images to be able to calibrate our results

File naming and directories

So we can easily find files and know instantly what they are, when they were taken, what temperature, which darks and flats to use for calibration etc. we are going to use the following file naming conventions. This fits easily into MaximDL's auto sequence system. The names also allow easy sorting of images when put into a common processing directory. Also the calibration masters needed for each dataset will be placed in the dir with the raw images.
