Hi All,

Based on the advise from Brendan and finding out how to change the F setting on my camera (not easy having to hold 2 buttons down at the same time) I managed to get what I feel are 2 good shots. I went to a local dark area in Jarrahdale as I used to live there although seeing was quite poor but no cloud. Massive dew problem my glasses fogging up within 15 minutes of arriving. I liked the pitta patta of Kangaroo feet around me as well.
  • First image is 10 shot at 2 minutes F4 ISO 400
  • Second image 6 Shots at 3 minutes F4 ISO 400, The timer shut down unexpectedly limiting to 6 shots.
Both look similar, I will investigate next deep sky night to try lower ISO setting with longer exposures to find a balance.

My wife came with me but without hearing it is difficult and got bored very easily so I didn't stay long. It was also getting cold and forgot to bring jumpers.

Just before we went, I manage to point the camera to the Milky Way and got a few 30 second shots F4 and ISO 400 again.
  • The first image shown is unprocessed basic what the camera saw
  • The second image was modified using Registax as I like the Histogram feature.
  • The Third image was procesed using GIMP as I like the "Levels" feature on that.
I really dont know if they are realistic at all and if brightening the image truely represent the colours in the image. The maybe a few hot pixels although I took a few dark frames DSS turned the whole image grey so I couldn't get the colours (still working on that).

Anyway was more a fun excercise than anything else and I suppose and education run for myself.
