I have been playing around with a Nikon D700 on a Takahashi P2Z mount taking pics from inner suburban Brisbane. Here are my first (IMHO) halfway reasonable attempts at Crux and Omega Centauri.
For the Crux pic I used an 85mm prime at f/4 and for Omega I used a 300mm prime also at f/4. Camera ISO was 400. Exposures were all quite short because of light pollution and a very slack polar alignment procedure (just point it roughly south...) I did some darks and stacked everything using ImagesPlus.
I thought I'd set the bar fairly low to start with and give myself lots of room to improve
I have certainly learned a lot in my first couple of nights...
Cheers,
Rick.
